Laboratory and laboratory equipment and laboratory supplies When used?

Experiments and laboratories Ever since human beings thought of improving the quality of life in and around themselves, they felt the need for experiments and laboratories.

What laboratories and what kind of laboratory equipment were needed by humans?

These laboratories were established in various cases, including:

Food Industry Laboratory for quality control of food used by humans, animals and livestock.
Genetics laboratory to study human and animal health.
Agricultural laboratory to check the quality level of plants, grains and fruits.
Water and wastewater laboratory to test the quality of water used as well as wastewater and its cycle to nature.
Pharmaceutical laboratory to control the quality of the drug and its effects on the disease recovery process.
Oil and gas laboratory to test the quality of gasoline, diesel, gas and oil products as fuel and heat source.
Industrial laboratory for testing and quality control of all metal and polymer production items, etc.
Research laboratory for research and promotion of scientific level, etc.
Paint and resin laboratory to inspect and control the quality of paint and resin for various industries, including automobiles.
Laboratory of polymers, rubbers and plastics to test and control the quality and strength of plastics, rubbers and polymers.
Physics lab to observe physical phenomena to collect data for the world around us.
The nanotechnology laboratory is capable of producing new materials, tools, and systems by taking control of molecular and atomic levels and using the properties that appear on those surfaces.

The laboratories used take different forms due to the different needs of specialists in different fields of science and engineering.

The Food Industry Laboratory may have food quality control devices such as a caldera to measure food protein, a Soxhlet device to measure food fat, a crude fiber device to measure fiber in food, a gluten device to measure wet and dry gluten, and flour. Numbering device for measuring alpha amylase activity in flour, refractometer for measuring beverage concentration and refractive index of oils, polarimeter for measuring light rotation

Oil and gas laboratory may have quality control devices and analysis of petroleum products, gasoline, diesel, carosine, furnace oil, engine oil and hydraulic oil, including: flash point measuring device, sulfur measuring device, viscosity measuring device, device Drop and cloud point measurement, copper corrosion measuring device, water measuring device in petroleum and oil materials, CCS engine oil device, MRV device, Novak device, Timken device, Forbal or four ball device, Oil shear stability device and Carl Fisher Etc

The physics laboratory may have a particle accelerator or a vacuum chamber, while the metallurgy laboratory may be a device for casting or refining metals or testing their strength.

The agricultural laboratory can also have equipment such as photosynthetic measuring device, chlorophyll meter, plant leaf surface measuring device, promoter device for plant stomata resistance, soil moisture meter and so on.

A chemist or biologist may use a wet lab, while a psychologist’s lab may be a room with one-way mirrors and hidden cameras where he can observe behavior.

In some laboratories, as is commonly done by computer scientists, computers (sometimes supercomputers) are used to simulate or analyze data. Scientists use other laboratories in other fields.

Sometimes engineers use laboratories to design, build and test devices. Laboratory equipment and laboratory supplies can usually be found in science laboratories and research rooms, and in schools and universities, in industry, government or military centers, and even on ships and spacecraft.

Classic laboratory equipment includes instruments such as laboratory glassware and chemicals and microscopes, as well as specialized laboratory equipment including devices such as spectrophotometers and calorimeters, atomic absorption, FTIR, ICP, and ICP MS.

Chemical laboratories also include laboratory vessels such as human, Erlenmeyer, balloons, forgers, reagents, and analytical devices such as HPLC or spectrophotometers.

Molecular biology laboratories and genetics laboratories also include autoclaves, microscopes, centrifuges, homogenizers and mixers, pipettes, thermal cycling (PCR), photometers, laboratory refrigerators and freezers, incubators, bioreactors, cabinets, immuno cabinets, and safety cabinets. Chemicals, humidifiers, laboratory scales, reagents and laboratory kits.

Larger or more advanced laboratory equipment and laboratory supplies are commonly referred to as scientific instruments.

Standards and safety issues in laboratories

In laboratories, there are usually hazards that may include toxins, toxic fumes from chemicals, infectious and microbial agents, flammable materials, explosives or radioactive materials, extreme temperatures, lasers, strong magnetic fields or high voltages. Therefore, precautions are vital. There are rules to minimize the risk of people in the laboratory as well as safety equipment to protect laboratory users.

The Occupational Safety and Health Administration (OSHA) in the United States, by recognizing the unique characteristics of the laboratory workplace, has set a standard for exposure to hazardous chemicals in laboratories.

This standard is often referred to as the “laboratory standard”. According to this standard, the laboratory is required to develop a chemical health plan (CHP) that addresses specific hazards at the site.

In determining the appropriate chemical health plan for a particular business or laboratory, you need to understand the requirements of the standard, assess current safety, health and environmental performance, and assess hazards. It is worth noting that CHP should be reviewed annually. Training is essential for safe operation of the laboratory. Instructors, staff, and management should work to reduce the likelihood of potential laboratory adverse events.

There are three main factors that contribute to the organization of the laboratory :

Researchers’ educational backgrounds and their socialization process.
The thought process involved in their work, including the type of research and equipment they use
Laboratory History.
