Basic knowledge of high and low temperature test chamber

First, the high and low temperature test chamber should be placed in a place with good ventilation, low humidity, and stable ground. There should be 60 ~ 70cm of maintenance space around.

2. The condenser should be cleaned once every three months. The condenser fan should be regularly inspected and the condenser should be decontaminated and dusted to ensure its good ventilation and heat exchange performance.

3. Cleaning and balance of circulating air blades and condenser fans: Similar to cleaning evaporators, because the working environment of the high and low temperature test chambers is different, many small particles such as dust and other particles will condense on the circulating air blades and condenser fans, which should be performed regularly Cleaning.

4. When working in the high and low temperature test box, the number of door openings should be minimized to reduce the overflow of cold air.

Fifth, the power supply voltage fluctuates greatly. If the power is repeatedly turned off, the use of the high and low temperature test box should be suspended, and the power supply should be turned off to prevent the compressor from being damaged. Do not turn on the compressor immediately after the high and low temperature test box is turned off. Stop the machine for 2-5 minutes before starting it.

Six, insist on taking out the test sample after each test, and wipe the inner wall of the high and low temperature test box to keep the inner box clean.

7. When long-term shutdown is not in use, the high and low temperature test chamber should be powered on regularly and monthly for at least 1 hour.

8. When transporting the high and low temperature test box, please pay attention to the body's inclination cannot exceed 30 °. During the transportation, keep the box vertical. Do not place it upside down or horizontally. Do not hold the doorknob or drag the condenser. To avoid damage.

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

图片
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
