Where does the biosafety cabinet need to be inspected regularly?

As the main clean equipment of biological experiment, biosafety cabinet is one of the laboratory equipments to prevent toxic and harmful air suspended particles from harming laboratory personnel, thus protecting laboratory personnel and environmental safety.

A good biosafety cabinet can not only protect people and environment, but also improve service life and efficiency. As laboratory equipment, it also needs to be maintained regularly. The following are the key points of biosafety cabinet maintenance.

Daily maintenance:
Using 70% alcohol (other fungicides depend on the material used by the user) to thoroughly purify the surface, side wall, back wall and window of the working area inside the biosafety cabinet. Do not use chlorine-containing fungicides, as it may cause damage to the stainless steel structure of the safety cabinet. The surface of ultraviolet lamp and power outlet should also be cleaned. When cleaning the inside area of the safety cabinet, the operator can not enter the safety cabinet except by hand.

Weekly maintenance:
1. Check the residue at the hole of the captured paper.

2. Wash the drainage tank thoroughly with 70% alcohol (other fungicides depending on the material used).

Monthly maintenance:
1. Use wet cloth to wipe the external surface of the safety cabinet, especially the front and upper parts of the biological safety cabinet, to clean up the accumulated dust.

2. Check the reasonable use of all maintenance accessories.

3. The above daily work items.

Quarterly maintenance:
1. Check any physical abnormalities or faults in the biosafety cabinet. Check the fluorescent tubes to make sure they work properly.

2. MEK (methyl-ethyl-ketone) can be used when stainless steel surface is hard to remove. After using WEK, wash stainless steel plate with clear water and liquid detergent quickly, and wipe with polyurethane cloth or sponge. Regular cleaning of stainless steel surface will keep it smooth and beautiful.

Annual maintenance:
1. Qualified certification technicians conduct performance certification for safety cabinets.

2. Replace an ultraviolet lamp.

What incubator should I use for fungi?

图片
There are many different types of incubators and the choice of the incubator should depend on what is being cultured. If the microorganism to be cultured is aerobic, then a normal incubator is sufficient; if it is anaerobic, then you need to buy an anaerobic incubator; if it is algae or fungi, it is better to have a light incubator. A light incubator is a piece of high-precision constant temperature equipment with light function; a light incubator is a special constant temperature incubation device for the cultivation of bacteria, molds, microorganisms, and breeding tests, especially practical for biological engineering, medical research, agriculture, and forestry science, aquaculture, animal husbandry and other fields engaged in scientific research and production use of the ideal equipment.　 The main technical parameters of the fungal incubator in the microbiology room of the laboratory require 1: Temperature requirements: 2 ~ 48 c, the temperature inside the incubator temperature u

Laminar flow Cabinet architecture introduction

图片
Laminar Flow Cabinet Clean Bench, also known as laminar flow Cabinet, can be mainly divided into two- person single, single side double side, horizontal vertical, etc. The structure is divided into the box, table, bracket, support foot, exhaust pipe, HEPA filter, pre-filter, etc.   Laminar flow cabinet design should have sufficient strength and stiffness, the weight should be light under the premise of good stability, the joints should be tight, according to the needs of the support foot can be self-locking structure universal wheel, but for the high requirements of seismic workbench without support feet and universal wheel, the operating area of the working surface can be made independent of the box platform. The inner surface of the single table is made of three sides of the wall. The wall surface is smooth and the joint is sealed. The glass and metal connection parts should also be sealed. The negative pressure air duct should be designed so that the air duct, plenum, filter, and su

The Control system is the core of the constant temperature and humidity chamber

The Control system is the core of the constant temperature and humidity chamber , it determines the temperature rise rate of the text chamber, precision, and other important indicators. Now the controller of the test chamber mostly adopts PID control, but also a few adopts PID and fuzzy control phase combination control mode. Because the control system of the thermostatic oscillator basically belongs to the category of software, and this part in the use of the process, generally there will be no problems. In the constant temperature and humidity chamber refrigeration principle diagram, we introduced the temperature and humidity chamber refrigeration system several important components of the working path. So how do these components work? The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work is consumed to raise the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the refrigerant c
