What should we pay attention to when using biosafety cabinet

Biosafety cabinet is the main safety protection equipment in biological laboratory. Unlike the purification workbench, biosafety cabinet can not only protect the safety of experimental samples, but also protect the safety of operators from pollution. It can effectively prevent the harmful and poisonous air suspended particles from harming the experimental operators. It is one of the important equipments for laboratory equipment to protect personnel.

Notes for the use of biosafety cabinets:
If the biosafety cabinet is not properly used, its protective effect may be greatly affected.

1. There is no need for ultraviolet lamp in biosafety cabinet. If the ultraviolet lamp is used, it should be cleaned weekly to remove dust and dirt that may affect its germicidal efficacy.

2. Open fire should be avoided in environments where there are few microorganisms in biosafety cabinets.

3. Lab operating rules on how to deal with spills should be posted in the laboratory. Every member who uses the laboratory should read and understand these rules.

4. At the time of installation and after a certain period of time, qualified professionals shall certify the operation performance and integrity of each biosafety cabinet according to the manufacturer's instructions to check whether it meets the national and international performance standards.

5. Because the remaining culture medium may cause microorganisms to grow and reproduce, at the end of the experiment, all items in the biosafety cabinet, including instruments and equipment, should be removed from the surface contamination and removed from the safety cabinet.

6. Biosafety cabinets must be cleaned up before moving and replacing filters.

7. Individual protective clothing should be worn when using biosafety cabinets.

8. One of the two alarms can be selected to equip the biosafety cabinet.

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
