Laboratory equipment is essential in any chemistry lab. It would be difficult to carry out experiments and tests without proper equipment. This article has compiled a list of Chemical Equipment exporters you should consider buying for your lab.
Essential furniture
A typical chemistry laboratory has workbenches with a sink, water faucet and reagent rack. Base cabinets can be added to these workbenches to hold glassware, equipment, and other items. Chemicals are stored in special cabinets. Workbenches have the water and gas hookups required to undertake numerous experiments. Aside from these, a teacher’s table, first aid kit, safety chart, and fire extinguisher are also required.
- WORKBENCH
A workbench is the foundation of every laboratory. Especially in a chemistry laboratory where one is working with caustic chemicals, high temperatures, damp environments, glassware, and so on, the quality of tabletop material is critical to enduring the circumstances above while also being robust enough.
- REAGENT RACK
A reagent rack is a storage area for ready-to-use reagents and glassware. It clears the workable area and eliminates accidental spills or damage during the experiment. It is often installed on top of the workbench.
It is available in single and double-tiered styles.
- SINK
Sinks are required for garbage disposal. They are available in various materials, including stainless steel and polypropylene (PP). Most are resistant to acids, alkalis, and solvents. PP sinks are recommended because they reduce glassware breaking on impact.
- FAUCET/TAP
Taps are required for glassware washings, especially burettes and pipettes and experiments.
- BASE CABINET
Base cabinets are storage cabinets beneath the worktop. They are used to keep large lab equipment and supplies on-site. Pre-storage techniques should be implemented, and essential items should be stocked before the start of each session to ensure inventory stock accountability and regular breakage monitoring in any scenario.
They’re built of eye-catching materials, including CRC Sheets, MDF, Particle Board, and Ply-Laminate. Many institutions use Base Cabinets as distinct entities, while others use Base Cabinets that are joined to Work Tops.
- CHEMICAL STORAGE UNIT/WALL CUPBOARD
The Chemical Storage Unit is a wall cabinet designed to store small amounts of chemicals or dangerous goods safely. It may also be used to store glassware, equipment, and other items.
- FUME HOOD
A fume hood is a sort of local ventilation equipment used in laboratories to reduce exposure to dangerous or poisonous gases or vapours.
- LAB STOOL
Lab Stools are lightweight and take up little room. It has an adjustable height and provides a pleasant resting spot during investigations.
- Essential Equipment/Glassware
A chemical laboratory must contain the following equipment/glassware.
- BEAKER
A beaker is a container used to combine, stir, and heat substances. It comes in a range of sizes. Most beakers include spouts on the rim to aid in pouring. Furthermore, some of them include markings to quantify the amount of liquid in them, however, this procedure is not very reliable. A watch glass is typically used to cover the opening to keep it clean.
- ERLENMEYER FLASK/CONICAL FLASK
The form of a conical flask is an inverted cone with a thin neck protruding from the conical base. This form facilitates mixing without the risk of spilling. The short neck hole allows for a rubber/glass stopper, which avoids spillage and contamination during mechanical shaking. It may also be readily secured to ring support prior to heating. It is available in a variety of sizes to accommodate various capacities. It, too, has a marking on the neck but should only be used for estimation.
- BOILING FLASK
A boiling flask, also known as a Florence flask, has a round bottom and a long neck extending from the base. It, too, is available in a variety of sizes. It is used to contain liquids and can simply be heated and swirled. It can also be readily closed with rubber or glass stoppers. Again, safety requires that this flask not be heated when sealed. Pressure buildup and explosions are possible and do occur.
- TEST TUBE
A test tube is a glass tube with a round closed and open end. It retains little amounts and is used for qualitative evaluation and comparison. A rubber or glass stopper may simply be used to close the open end. They’re also simple to close with a rubber or glass stopper.
- WATCH GLASS
A watch glass is a concave spherical piece of glass. It can contain a small amount of liquid or material. It evaporates liquid and may also serve as a beaker lid.
- CRUCIBLES
A crucible is a tiny cup capable of withstanding high temperatures. They are used to heat items and have a lid. It can be made of any high-temperature-resistant material.
- FUNNEL
A funnel is a device that moves liquids or fine-grained particles into small-mouth containers. Its conical mouth and cylindrical bottom keep spills to a minimum. It is often constructed of glass or plastic.
- GRADUATED CYLINDER
A graduated cylinder, measuring cylinder, or mixing cylinder is employed to determine the volume of a liquid. It is slender and cylindrical in form. Each designated line on the graduated cylinder shows the volume of liquid poured into the cylinder. When someone stands in the center, the liquid at the borders will be higher than the liquid in the center, sloping down like the sides of a trampoline. This is known as the meniscus. To effectively read the volume, align the lowest point of the meniscus with the nearest marker while maintaining the cylinder level.
- VOLUMETRIC FLASK
A volumetric flask (also known as a measuring flask or graduated flask) is a circular flask with a long neck and flat bottom that is calibrated to hold a specific volume at a specific temperature. Volumetric flasks are used to make exact dilutions and standard solutions. They come with protective caps that prevent anything from getting in or out.
- DROPPER
The dropper is a tiny glass tube with one end having a narrow tip and the other having a rubber bulb. They can hold a little liquid by sucking it up and squeezing it out in small drips. These can be used to add an indication to a titrated solution.
- PIPETTE
A pipette is a device that is used to deliver a measured volume of liquid, most commonly as a media dispenser. It is available in various designs for various uses, with varying degrees of accuracy and precision. It works by establishing a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw liquid up and distribute it into another container.
- BURETTE
A burette is a graded glass tube with a stopcock at one end and a tapered capillary tube at the other. It is used for dispensing a variable amount of a chemical solution and measuring that amount simultaneously through markings along the length of the tube. The stopcock valve controls liquid flow from the tube to the burette tip.
- RING STAND
The ring stand supports burets, beakers, flasks, crucibles, and other containers or a Bunsen burner above other containers. Other elements are frequently required to complete the purpose when utilizing a ring on the stand. Wire mesh is put over the ring to spread uniform heat and support the beaker. Crucibles are suspended using a clay triangle with an open center.
- TONGS AND FORCEPS
Tongs and forceps are used to hold items that should not be handled by hand due to their size or heat. Aside from general-purpose tongs, others are designed to hold specific items such as beakers, test tubes, and so on. Forceps are used to grasp tiny objects, such as solid chemical pieces, so they may be handled and put in containers securely.
- SPATULA
The spatula is similar to a spoon and is used to scoop solid substances. They are primarily used to scoop a chemical from its original container and place it on a weigh boat to be weighed on a balance.
- THERMOMETER
A laboratory thermometer is used to precisely measure the temperature of liquids. It can be constructed of glass or a thermocouple composed of various metals. There are additional digital and infrared variants available.
- BUNSEN BURNER
A Bunsen burner is a mechanical device that, when linked to a flammable gas source, creates a single open gas flame that is used for heating, sterilizing, and combustion. A knob regulates the gas flow quantity, while a rotating collar controls the airflow. Both of these must be adjusted to provide an optimum flame for heating applications. A striker is used to light the burner. Natural gas (mostly methane), liquefied petroleum gas, propane, butane, or a combination of the two can be used.
- BALANCE
To weigh chemicals, a balance is employed. The chemicals are always kept in a container and are never placed directly on balance. It is critical not to shift a balance since it has been calibrated for its precise location. To use a balance to weigh a chemical, first balance the empty container the chemical will be in. After you’ve taken your reading, push the “zero” button on balance. Remove the container from the balance and replace it. Reweigh after adding the chemical to determine the weight of the chemical alone.
