Advantages and application of vacuum drying oven

Method of use

1, items into the oven, the need for drying will shut the door and tighten the door shake handshandle, close valve, open the vacuum valve, the vacuum drying oven side airway with vacuum rubber hose connected to the vacuum pump, turn on the vacuum pump power, began to smoke gas, when the vacuum degree of vacuum gauge instructions to you need, first close the vacuum valve, then close the vacuum pump, the oven in the vacuum state.

2, after turning on the power supply, open the power switch, indicator, the said work is normal, the instrument shows studio temperature, and then adjust to the set temperature control instrument, studio began to heat, green light on the control instrument said electricity to heat up, when the temperature of the instrument display instrument constant temperature 60 minutes should set temperature.

3. Choose different drying time for different articles and different temperatures. If the drying time is longer and the vacuum degree drops, then the vacuum pump should be opened first and then the vacuum valve should be opened.

4. After the drying of the vacuum drying oven, the power should be turned off first, and the return air valve should be rotated to remove the vacuum in the oven, and then the door should be opened to take out the items.

5. Under vacuum condition, the control temperature shall not be lower than 50℃. If below 50℃, the standard thermometer test value and the instrument display value is not consistent, is a normal phenomenon. This phenomenon does not affect temperature control and temperature above 50℃.

Advantages of vacuum drying oven:

1. Vacuum environment greatly reduces the boiling point of liquid to be expelled, so vacuum drying can be easily applied to heat sensitive substances.

2. For samples that are not easy to dry, such as powder or other granular samples, vacuum drying method can effectively shorten the drying time.

3. All kinds of mechanical parts with complex structure or other porous samples are cleaned and then vacuum dried, leaving no participating substances after they are completely dried.

4, safer use -- in vacuum or inert conditions, completely eliminate the possibility of oxide thermal explosion.

5. Compared with normal drying, which relies on air circulation, the powdered sample will not be blown or moved by flowing air.

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
