How to evacuate the Vacuum drying oven?

 There are many models of Vacuum drying ovens, but the basic structure is similar, generally consisting of three parts: the Vacuum drying oven, electric heating system, and automatic temperature control system.

Connect the vacuum pump with the vacuum valve, open the vacuum pump and the vacuum valve in turn, and pump the vacuum.

Caution.

①According to the performance of the vacuum pump, the pressure gauge shall be the limit value of the vacuum pump.

When the vacuum degree is reached, close the vacuum valve first (if the vacuum valve is not tightly closed, it needs to be replaced in time), and then turn on the power of the vacuum pump. (a) Closure or removal (to prevent back drafting).

③ Observe the vacuum pressure gauge to ensure that the value is stable without significant fluctuations.

④If the vacuum degree is lower than the requirement of dry goods, open the vacuum pump power and vacuum valve again and continue to evacuate. Vacuum pump lifetime.

The vacuum drying oven KZ series can correct the measurement error of the sensor, PB = actual vacuum degree - measured display value. When the measured value does not reach the set value of ±0.50KP (5.0Mb) in continuous vacuum alarm minutes, the alarm light flashes. The buzzer sounds and can be silenced by pressing any key. The vacuum drying oven DZF series can be fully adjusted to correct the error caused by the sensor (high temperature) measurement. PK=1000 * (actual temperature value - laboratory measured value) / laboratory measured value.

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
