GLASS AND PORCELAIN

GRADUATED CYLINDER

 graduated cylinder -(or measuring cylinder) is a piece of laboratory glassware used to measure the volume of liquids. It is used to accurately measure the volume of chemicals for use in reactions.

Often, the biggest graduated cylinders are made of polyethylene or other stiff plastic, making them lighter and less fragile than glass, but more difficult tosterilize.

                                           

BEAKER

A beaker is a simple container for stirring, mixing and heating liquids commonly used in many laboratories. Beakers are generallycylindrical in shape, with a flat bottom.^[1] Most also have a small spout (or "beak") to aid pouring as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres.

TEST TUBE

A test tube, also known as a culture tube or sample tube, is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top, usually with a rounded U-shaped bottom.

FLORENCE FLASK

A Florence flask is a type of flask used as an item of laboratory glassware. It is used as a container to hold liquids. A Florence flask has a round body with a flat bottom and a single long neck. It is designed for uniform heating, boiling, distillation and ease of swirling; it is produced in a number of different glass thicknesses to stand different types of use.

ERLENMEYER FLASK

An Erlenmeyer flask or conical flask^[1] is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer, who created it in 1860.

WATCH GLASS

A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, and so gas exchanges still occur. It is also used for heating small amount of substances. When used as an evaporation surface, a watch glass allows closer observation of precipitates or crystallisation, and can be placed on a surface of contrasting colour to improve the visibility overall.

CRUCIBLE

A crucible is a container that can withstand very high temperatures and is used for metal, glass, and pigment production as well as a number of modern laboratory processes. While crucibles historically were usually made from clay,^[1] they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents.

BURRETE

A burette (also buret) is a device used in analytical chemistry for the dispensing of variable, measured amounts of a chemical solution. A volumetric burette delivers measured volumes of liquid. Piston burettes are similar to syringes, but with precision bore and plunger. Piston burettes may be manually operated or may be motorized.^[1] A weight burette delivers measured weights of liquid.

MEDICINE DROPPER

Medicine droppers are tools usually made from a long piece of glass or plastic with a flexible rubber handle that is used to suction liquids in and out of the device. Medicine droppers have other uses outside the medicine field and can be handy household items.

FUNNEL

A funnel is a pipe with a wide, often conical mouth and a narrow stem. It is used to channel liquid or fine-grained substances into containers with a small opening. Without a funnel, spillage would occur.

STIRRING ROD

A Glass rod, stirring rod or stir rod is a piece of laboratory equipment used to mix chemicals and liquids for laboratory purposes. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, with rounded ends. Like most laboratory glass, stir rods are made of borosilicate(commonly known as pyrex).

MORTAR AND PESTLE

A Pestle and mortar is a device used since ancient times to prepare ingredients or substances by crushing and grinding them into a fine paste or powder. The mortar (/ˈmɔrtər/) is a bowl, typically made of hard wood, ceramic or stone. The pestle (/ˈpɛsəl/) is a heavy club-shaped object, the end of which is used for crushing and grinding. The substance to be ground is placed in the mortar and ground, crushed or mixed using the pestle.

EVAPORATING DISH

An evaporating dish is a piece of laboratory glassware used for the evaporation of solutions and supernatant liquids,^{[note 1]} and sometimes to their melting point. Evaporating dishes are used to evaporate excess solvents - most commonly water - to produce a concentrated solution or a solid precipitate of the dissolved substance.

THERMOMETER

A thermometer is a device that measures temperature or a temperature gradient. A thermometer has two important elements: the temperature sensor (e.g. the bulb on a mercury-in-glass thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer).

PETRI DISH

Petri dishess a shallow cylindrical glass or plastic lidded dish that biologists use to culture cells^[2] – such asbacteria – or small mosses.^[3] often used to make agar plates for microbiology studies. The dish is partially filled with warm liquid containing agar and a mixture of specific ingredients that may include nutrients, blood, salts, carbohydrates, dyes, indicators, amino acids or antibiotics. Once the agar cools and solidifies, the dish is ready to be inoculated ("plated") with a microbe-laden sample. Virus or phage cultures require a two-stage inoculation: after the agar preparation, bacteria are grown in the dish to provide hosts for the viral inoculum.

PIPET

A pipette, pipet, pipettor or chemical dropper is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes. Many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid. Measurement accuracy varies greatly depending on the style.

MAGNIFYING GLASS

A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object. The lens is usually mounted in a frame with a handle (see image).

METAL EQUIPMENT AND ACCESSORIES

IRON STAND

A metal rod attached to a heavy metal base. The heavy base keeps the stand stable, and the vertical metal rod allows for easy height adjustment of the iron ring/clamp. (A tripod can sometimes be used in place of an iron stand.)

IRON RING

An iron ring, sometimes called an epic ring of coolness,^[1] is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder.^[2] Iron rings are commonly used in chemistry laboratories for supporting apparatus above the work surface.

TRIPOD

A laboratory tripod is a piece of three-legged equipment commonly used to conduct experiments in laboratories. It is used as a platform to hold and support glassware, such as beakers and flasks, during experiments and when the glassware is not in use. A tripod’s height is easily adjustable to fit varying individual requirements.

CLAY TRIANGLE

A clay triangle is a piece of laboratory equipment used in the process of heating substances. It is used in conjunction with other lab equipment to create a stable framework in which to place a substance -- usually a solid chemical -- while it is heated to a high temperature.

DEFLAGRATION SPOON

A deflagration spoon is used in chemistry experiments when the burning of phosphorus, sulfur or another substance is required. It is capable of withstanding high temperatures and is equipped with features to facilitate working in this environment, such as a long handle angled to keep heat away from the hand.

BUNSEN BURNER

A Bunsen burner, named after and invented by ^[1] Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion. The gas can be natural gas (which is mainlymethane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.

UNIVERSAL CLAMP

Multipurpose clamp may be used to hold plates, secure tubing, or grip equipment. Constructed of nickel-plated steel for strength. Extra-robust, tempered-steel springs provide continuous pressure when loaded. Sixteen-pound gripping force prevents slippage.

BURETTE CLAMP

They are made from corrosion-resistant metals. Single burette clamps hold one burette, test tube or flask, and double clamps hold two. Double burette clamps also accommodate flasks and test tubes.

PINCH COCK

A clamp used to regulate or close a flexible tube, especially in laboratory apparatus.

COPPER WIRE

Copper has been used in electric wiring since the invention of the electromagnet and the telegraph in the 1820s.^[1][2] The invention of thetelephone in 1876 created further demand for copper wire as an electrical conductor.^[3]

Copper is the electrical conductor in many categories of electrical wiring.^[3][4] Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment.^[5] Copper and its alloys are also used to make electrical contacts. Electrical wiring in buildings is the most important market for the copper industry.^[6]Roughly half of all copper mined is used to manufacture electrical wire and cable conductors.

TRIANGULAR FILE

A triangular file is any file that has a triangular cross section. The file has three tapered sides, which are used to file the internal surfaces of objects with acute angles. Triangular files are typically used by carpenters to sharpen the teeth of hand saws or to smooth various surfaces.

TEST TUBE HOLDERS

Test tube holders are used to distance a person from potentially dangerous tasks when using chemicals in test tubes. They not only extend a person's reach, they protect the user from harm while performing basic lab tasks.

TEST TUBE RACK

 Test tube racks are commonly used in laboratories to keep test tubes upright so that the equipment does not roll away, spill or become accidentally cracked.

TEST TUBE BRUSH

Test tube brushes are great for cleaning test tubes and other lab ware including tubing. Constructed of quality bristles mounted on a twisted galvanized wire the brush is tufted at the end for cleaning the bottom of a test tube.

RUBBER TUBING

Rubber tubing is used in flow lines for fluids and gases in a variety of hydraulic, pneumatic, process, medical, and specialty applications. Rubber tubing is flexible and resilient due to its natural or synthetic rubber construction.

GLASS TUBING

Glass tubes or glass tubing are hollow pieces of borosilicate or flint glass used primarily as laboratory glassware. Glass tubing is commercially available in various thicknesses and lengths. Glass tubing is frequently attached to rubber stoppers.

CRUCIBLE TONG

Crucible tongs are tools that can be used in either a laboratory setting or an industrial setting. In both cases, the tongs are used to safely move a piece of equipment called a crucible that contains potentially dangerous materials that must be handled very carefully.

RUBBER STOPPER

Stoppers fit tightly to prevent chemical leaks. Our 5 mm glass tubing fits in the one- or two-hole rubber stoppers. For small test tubes use #00 stoppers. Use #0 for large test tubes, and #1 for extra large. Use #6.5 stoppers for 250 ml flasks. Use a cork borer to drill holes in the corks.

CORK

Cork is an impermeable^[ buoyant material, a prime-subset of bark tissue that is harvested for commercial use primarily fromQuercus suber (the Cork Oak), which is endemic to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobicsubstance, and because of its impermeable, buoyant, elastic, and fire retardant properties, it is used in a variety of products, the most common of which is for wine stoppers. The montado landscape of Portugal produces approximately 50% of cork harvested annually worldwide, with Corticeira Amorim being the leading company in the industry.^[1] Cork was examined microscopically by Robert Hooke, which led to his discovery and naming of the cell.

CORK BORER

A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing.^[1] Cork borers usually come in a set of nested sizes along with a solid pin for pushing the removed cork (or rubber) out of the borer. The individual borer is a hollow tube, tapered at the edge, generally with some kind of handle at the other end.

RUBBER BULB ASPIRATOR

Made of rubber for resistance to most solvents and oils. Single bulb, for pressure only. Consists of 105 mm x 53 mm diameter glossy black rubber bulb with metal valves and 4 inch length of 3/16 inch I.D. black tubing. For use on wash bottles, etc. Capacity is approximately 75 mL.

WIRE GAUZE

In a laboratory, wire gauze is used to hold stuff on a ring stand; for instance, if you want to boil some water in a beaker using a Bunsen burner, you put a wire gauze on a ring stand, then put the flame under it. 

NICHROME WIRE

Nichrome wire has a unique characteristic: It heats up when electricity is applied. Manufacturers and hobbyists use nichrome wire in many applications where wire must get hot or must withstand high temperatures.

PLATFORM BALANCE

The platform balance is a form of equal-arm balance in which two flat platforms are attached to the top side of the beam, one at each end. Such a balance has a rider, or weight, mounted on a bar that has a calibrated scale, is parallel to the beam, and connects the supports of the two platforms. This rider is moved along the bar, its edge marking decimal fractions of the unit weight. 

SET OF WEIGHTS

weights of various masses used to determine the mass of bodies by weighing. A set of weights can determine the mass of a body whoseweight does not exceed the total weight of the weights in the set.All sets of weights produced characteristically have, with respect to each order of magnitude mass, four weights whose masses are in theratio 1:2:2:5. Four is the minimum number of weights permitting the reproduction of any mass from one to ten within a given order ofmagnitude. Thus, weights whose masses are 1, 2, 2, and 5 kg are sufficient to reproduce masses from 1 to 10 kg. A set of weights usuallycontains weights that cover two or three orders of magnitude, for example, from 1 to 500 g.

PLASTIC WASH BOTTLES

A wash bottle is a squeeze bottle with a nozzle, used to rinse various pieces of laboratory glassware, such as test tubes and round bottom flasks.

Wash bottles are sealed with a screw-top lid. When hand pressure is applied to the bottle, the liquid inside becomes pressurized and is forced out of the nozzle into a narrow stream of liquid.

CALCIUM CHLORIDE TUBE

The drying tube, is usually used during mositure sensitive operations.

It is usually filled with Cacl2( A dessicant), and connected to your reacions, allowing positive pressure to escape, without sucking in any moisture, to the reaction.

THISTLE TUBE

A thistle tube is a piece of laboratory glassware consisting of a shaft of tube, with a reservoir and funnel-like section at the top. Thistle tubes are typically used bychemists to add liquid to an existing system or apparatus. Thistle funnels are used to add small volumes of liquids to an exact position. Thistle funnels are found with taps or without taps.
