At the laboratory

Life threatening injuries can happen in the laboratory. For that reason, students need to be informed of the correct way to act and things to do in the laboratory. The following is a safety checklist that can be used as a handout to students to acquaint them with the safety do’s and don’ts in the laboratory.

Conduct

• Do not engage in practical jokes or boisterous conduct in the laboratory.

• Never run in the laboratory.

• The use of personal audio or video equipment is prohibited in the laboratory.

• The performance of unauthorized experiments is strictly forbidden.

• Do not sit on laboratory benches.

Apparel in the Laboratory

• Always wear appropriate eye protection (i.e., chemical splash goggles) in the laboratory.

• Wear disposable gloves, as provided in the laboratory, when handling hazardous materials. Remove the gloves before exiting the laboratory.

• Wear a full-length, long-sleeved laboratory coat or chemical-resistant apron.

• Wear shoes that adequately cover the whole foot; low-heeled shoes with non-slip soles are preferable. Do not wear sandals, open-toed shoes, openbacked shoes, or high-heeled shoes in the laboratory.

• Avoid wearing shirts exposing the torso, shorts, or short skirts; long pants that completely cover the legs are preferable.

• Secure long hair and loose clothing (especially loose long sleeves, neck ties, or scarves).

• Remove jewelry (especially dangling jewelry).

Every research centers, schools, colleges, universities in the country have their own chemistry equipment in their laboratory. A standard chemistry laboratory has all the essential chemistry equipment which includes a wide range of apparatus like glassware, thermometers, distillation equipment, sterilizers, and so on. These lab equipments must be of high quality, durable and safe to use. They should also be resilient and has the ability to withstand chemical reactions and temperature and pressure fluctuations. High quality chemistry equipment in these laboratories must be manufactured from quality materials. Laboratories that require a large quantity of chemistry lab equipment should approach established laboratory equipments suppliers who can offer them competitive prices for their purchases.

Laboratories need to be equipped with different kinds of chemistry equipment to function efficiently and perform various research applications. Here are some of the various chemistry lab equipments and their respective uses. Beakers refer to the large, glass sized cups used for holding large amounts of solution. These chemistry equipment are generally made up of plastic or tempered glass and have wide mouths for pouring the solutions easily.  Vials are the smaller versions of a beaker and are used for holding or measuring small amounts of liquids. These chemistry equipment are used when liquid is needed to be added in the form of small droplets. Pipets are tiny disposable chemistry lab equipments used for adding droplets of liquid in another vessel like a beaker, flask or vial. This chemistry equipment has to be discarded after each use as they are so small that they cannot be cleaned.

Test tubes are also chemistry equipment which refers to the long glass tubes used for observing reactions or heating chemicals. Glass burettes are cylindrical in shape and have volumetric markings on its outer surface. They have stop cocks at the lower end. These chemistry equipment are used to give out the required and precise quantity of liquid solutions in various experiments. Nowadays, the digital burettes are used and they have electronic dispensers which make the job easier. Another important chemistry equipment in the laboratory is the Bunsen burners which assist the observer in heating various solutions. They are also used to sterilize glass tubes. These chemistry equipment are vertical gas stoves connected to a gas source. They are a safe device which uses butane and propane gases. The Bunsen flames of this chemistry equipment can be adjusted according to the amount of heat required to conduct the experiment.

The plastic funnels are useful chemistry equipment in the laboratory. They are especially used to canal the liquid into beakers that have narrow openings. The lower end of this chemistry lab equipment is a cylindrical small tube which can be placed on the narrow opening of the beaker or container. Deflagration spoons are used to warm and burn different substances in the chemistry laboratory. This chemistry equipment is designed in such a way that it consists of a long handle, thus safeguarding the user’s hand from heat. Another chemistry equipment is the digital thermometers which are instruments used to measure the exact temperature in the chemistry laboratories.  The digital presentation of the temperature gradients is also helpful to the user as it provides faster and accurate temperature measurements.
