What is the difference between a constant temperature water bath and a constant temperature oil bath?

Constant temperature water bath pot and constant temperature oil bath pot are used for medical and health, Medical College inspection and laboratory, industrial and mining enterprises, scientific research units for constant temperature auxiliary heating, and are one of the common laboratory equipment.

Constant temperature water bath pot is suitable for heating water at constant temperature. Because the water temperature is at standard atmospheric pressure, the maximum temperature is 100 C, and constant temperature water bath pot can also raise the temperature to 100 C, which can be used for constant temperature of samples in the temperature range.

Constant temperature oil bath pot is suitable for oil constant temperature, but there are many kinds of oil, different oils have different effects. This needs to depend on the flash point temperature of oil. Some oils have very low flash point temperature, such as paraffin oil, which is 163 C. This kind of oil is not suitable for oil bathtub. Because the temperature of oil bath can be set to 300 C, if the temperature of oil exceeds the flash point temperature, it will be very dangerous, and even cause the phenomenon of oil bath caught fire. So when choosing oil, we need to choose oil with relatively high flash point temperature, such as cottonseed oil, whose flash point can reach 321 C.

Can a constant temperature oil bath be used as a water bath? In fact, it is possible. The temperature range of the constant temperature oil bath pot is room temperature + 5 ~ 300 C. This range includes the temperature range of the water bath pot, so it can be used as a water bath pot. The difference between constant temperature oil bath pan and constant temperature water bath pan lies in the temperature range. The constant temperature oil bath pan is needed for high temperature and constant temperature, while the constant temperature water bath pan is enough for ordinary constant temperature.

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
