The material comparison of different types of vacuum drying oven

 The material comparison of different types of vacuum drying oven

Product Comparison Presentation.



1.For the construction and material differences between the KZ, DZF  vacuum drying oven models, described below.

  The inner cavities of KZ and DZF-S series are made of SUS304 stainless steel, which is very suitable for research laboratories with acid and alkali resistant and corrosion resistant environments. Only the inner cavity of the DZF series without S is made of cold-rolled steel plate, which can be selected by users according to actual needs.

The KZ series adopts the international advanced preheating technology of the inner cavity. The three-sided annular stainless steel heating tube preheats the inner wall of the inner cavity first, which makes the temperature rise faster and the temperature stability better (picture). The KZ-G high-match model is equipped with laminar heat transfer technology, which transfers the heat directly to the sample through the aluminum laminar, and solves the problem of weakened heat transfer in a vacuum state better (with diagram), and is also equipped with valve electric control technology, vacuum degree automatic control, without manual control, more convenient operation and higher vacuum accuracy (with diagram).   DZF series can be divided into three kinds of heating structure, respectively, the 50 series of four-sided inner wall heating, 60 series of two-sided heating, and 30 series of layered independent heating (with the picture). The four-sided heating is more uniform than the two-sided heating, and the 30 series can realize the function of controlling the temperature of each laminar area separately. Therefore, customers should choose a suitable series according to their needs when selecting a model.

2. Insulation

KZ series use imported environmentally friendly aluminum silicate insulation cotton, and the use of isolation insulation technology: the inner liner and shell hollow isolation design, to avoid the loss of energy due to heat transfer (with pictures).

DZF series use the traditional rock wool filling, providing effective insulation.

3. Manufacturing process

   The KZ series uses thicker plates, and the sheet metal parts are all laser cut and CNC shaped (picture), which makes the production process and precision better than DZF.

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
