What reason is oven leakage vacuum?

What reason is oven leakage vacuum?There are many reasons why vacuum ovens break down. Kenton will show you.

1. The oven body is not fully welded, and there is air leakage at the jointing joint. You can find the air leakage point by injecting washing powder water or aeration.

2. The door of the industrial oven is not properly connected, or the sealing strip is aged or damaged, so it cannot be sealed.

3. Air leakage exists in the vent (valve) of vacuum oven, which cannot be closed completely.

4. The solenoid valve in the suction hole position of the vacuum oven fails to suction normally. When the vacuum is finished, the solenoid valve fails to complete the suction port and leakage occurs.

5. There is something wrong with the connecting pipe in the oven (the rubber pipe is aging, damaged or leaking).

6. In addition, after the end of vacuum pumping, the vacuum meter will rotate slightly after heating, which is normal, because the vacuum degree of the vacuum oven is not absolute, but relative, and the tiny amount of air heated expansion will cause the vacuum meter to recover slightly.

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
