What details should we pay attention to when using vacuum dryer

Vacuum drying chamber is widely used in biochemistry, chemical pharmacy, medical and health, agricultural research and other research fields. It is used for powder drying, baking and disinfection and sterilization of various glass containers. It can also greatly reduce the boiling point of the liquid to be expelled in vacuum environment, so the vacuum drying box can be well used in the experiment of powder and granular samples. Compared with the ordinary drying chamber which relies on air circulation, the powder sample will not be blown away when drying.

Vacuum drying box whether in use or in place, there are several points to pay attention to, the following are the details of the vacuum drying box can not be ignored.
1. Vacuum drying box should not be installed in the place where sunlight can directly irradiate, otherwise the equipment will not achieve the expected performance.

2. Placing the environment space needs a bit larger. If a vacuum drying box is used in a narrow and closed space, it will cause the equipment to be unable to heat and affect the normal operation of the equipment. The distance between the equipment and the wall should be 10 centimeters.

3. High-temperature equipment such as boilers or heaters should not be near the equipment of vacuum drying box. Excessive external heat will affect the normal operation and control performance of vacuum drying box.

4. The humidity of the place near the vacuum drying box should not exceed 70%. Excessive ambient humidity will lead to leakage or electric shock of the equipment. Vacuum drying box should not be used outdoors.

5. Vacuum drying box should not be placed near flammable or corrosive gases. Otherwise, it is easy to cause leakage and electric shock due to corrosion, which may cause explosion or fire.

6. Vacuum drying boxes should be placed on a solid and flat ground, which is conducive to the normal operation of the equipment and avoids the shaking and noise caused by the wrong placement of the equipment.

Before the first start-up of the vacuum drying box, please follow the following procedures:
1. Open the door by pulling the door handle upward and pulling the door outward to the right.

2. Shield the shelf by hand, and then pull the push rod out of the shelf to loosen.

3. Remove the shelf accessories inside the equipment and wipe the shelf and the inner wall of the box with gauze for cleaning.

4. Put the shelf into the equipment according to the drying or experimental requirements, then press the push rod inward, and the shelf can be installed.

5. Access to vacuum pump and nitrogen cylinder (user-owned);

6. If you need to place items on the same shelf, leave space between them for drying.

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
