COMMONLY USED LABORATORY EQUIPMENT
Aspirator
An aspirator is also known as an eductor-jet pump ,or a filter pump. T his is a device that is able to produce a vacuum by using the venturi effect. In anaspirator there is a fluid (either liquid or gaseous) that flows through a narrowing tube. Once the tube starts narrowing, the fluid's speed is able to increase. This is because of the aforementioned venturi effect. The pressure eventually decreases and from her onwards, the vacuum is taken from this point.

Crucible with Cover
A crucible is a small container that is used to hold reactants during heating at higher temperatures. The crucible lid covers it to ensure that nothing enters it during the reaction and that nothing also leaves during the reaction.

Crucible Tong
Laboratory tongs are large pincers for grasping and lifting vessels of heat-resistant material used in high temperature chemical reactions. They can be used to hold or pick up many items, but work best as tongs for picking up a hot evaporating dish.Crucible tongs are welded steel tools used to lift a hot crucible from a furnace or for other items you may not want to handle with your hands. Crucible tongs may also be used to prevent any inaccuracies regarding mass measurements as any moisture or oil will affect the readings and accuracy.

Iron stand
A ring stand is used to provide support for other equipment and a means of raising equipment above the work surface. Often times an iron bar screwed into an iron base makes up a ring stand; however, the holes you see in the lab desk surface are receptacles for aluminum rods that can be used in much the same manner as a ring stand.

Litmus Paper
Litmus paper is used for measuring the pH of a liquid. The pH is a measurment of how acidic or basic a liquid is. Red or blue litmus paper contains a compound that changes colors at a certain pH. There are a variety of different litmus papers which change colors at a specific pH. Generally, red is associated with an acidic solution (pH < 7) and blue with a basic solution (pH > 7). By dipping a litmus paper in a solution and watching for a color change, you can determine if the pH is below or above a certain threshold.

Mortar and Pestle
A mortar and pestle is a tool used to grind and mix substances. The pestle is a heavy small bat, made from porcelain, wood or other materials, whose rounded end is used for pounding and grinding. The mortar is a bowl, which can be made from porcelain, wood, carved stone or other materials. The substance is ground between the pestle and the mortar by rubbing or pounding the substance with the pestle against the wall of the mortar, thus turning it into a fine powder.

pH meter
The pH meters measures the activities and not the concentrations of hydrogen ions. The meter works like a voltmeter by measuring the voltage that is produced by the solution. A typical pH meter consists of two parts: one special measuring probe (a glass electrode) or two measuring probes that are inserted into the solution whose pH is required and an electronic meter that measures and displays the pH reading.

Rubber Stopper
The primary purpose of a rubber stopper is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the contents of laboratory glassware from air. Last, the use of rubber stoppers allows experimenters to shake or mix solutions without spilling them.

Rubber tubing
Rubber tubing is often connected to a condenser, which is a laboratory tool used in the process of distillation. The rubber tubing helps cool water to flow in and out of the condenser and helps the heated water vapour in the condenser return to its liquid state.

Separatory Funnel
Separatory funnel also known as separation funnel, separating funnel, or colloquially sep funnel, is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture between two immiscible solvent phases of different densities. Typically, one of the phases will be aqueous, and the other a non-polar lipophilic organic solvent such as ether, MTBE,dichloromethane, chloroform, or ethyl acetate. Most organic solvents float on top of an aqueous phase, though important exceptions are most halogenated solvents.A separating funnel takes the shape of a cone with a hemispherical end. It has a stopper at the top and stopcock (tap), at the bottom. Separating funnels used in laboratories are typically made from borosilicate glass and their stopcocks are made from glass or PTFE. Typical sizes are between 50 mL and 3 L.

Sets of Weights
Laboratory weights are used for two-pan balances. The object to be weighed is placed on one pan, and weights are placed on the other pan until the scale is balanced. The weights add up to the weight of the contents of the other pan. Weights are also used to calibrate and/or check the accuracy of other weighing instruments.

Spatula
Laboratory spatulas are tools that resemble small paddles, teaspoons or shovels. These spatulas are typically made out of stainless steel, rubber or plastic. Many laboratory spatulas are disposable, while others are reusable. Laboratory spatulas are ideal for removing chemicals or compounds from small bottles, and for applying cultures or other substances to slides for microscope viewing. It is also use to scrape away samples of biological materials, or chemical precipitates and residues. Many brands are resistant to acids, bases and solvents, which makes them safe for use in a broader spectrum of compounds.

Stirring rod
The function of a stirring rod is to mix or stir liquids. Mixing will speed up any reaction that takes place in the test tube or flask. A glass stirring rod can also be used for decanting (pouring off) a liquid from a precipitate or sediment. The rods are thicker and longer than a drinking straw and made from a special laboratory glass called borosilicate. The thickness of the rod makes it unaffected by cold or heat.

A test tube is a relatively slim glass or plastic vessel with a rounded bottom. They are designed to hold small quantities of chemicals and feature a flared lip to make pouring easier. Test tubes can hold liquid or solid chemicals and can be used to contain small chemical reactions. The slimness of the test tube reduces the spread of any vapors that may be produced by the reaction.

The test tube holder is a piece of laboratory equipment that is used to hold test tubes. They are made out of metal and are used by squeezing the handles to open the other end, and inserting the test tube. Test tube holders are typically used when heating the test tube is necessary, or for when caustic materials are being handled. Test tube holders are a staple in most commercial and student laboratories.

Laboratory tripod is a three-legged equipment, generally used as a platform of some sort. The word is derived from Greek word tripous, meaning "three feet". A tripod stand has three legs and is widely used in laboratories to conduct various experiments.
This lab equipment is used to support and hold various flasks, beakers and other glass ware when not in use and also during experiments. The stands are specially constructed using light metals for light weight and ease of carrying. The height of laboratory tripod can also be adjusted according to individual requirements.

Wire gauze can be used to support a container such as a beaker or flask during heating. When the Bunsen burner flame is beneath it, with a tripod, the wire gauze helps to spread the flame and heat out evenly over the container. It is frequently used in combination with an iron ring and ring stand with a Bunsen burner underneath it.
