Kenton laboratory vacuum drying oven original inner cavity preheating technology and heat transfer technology of the partition plate, increase the contact area between the partition plate and the preheating cavity so that the temperature of the partition plate and the preheating cavity remain the same. the temperature uniformity in the vacuum drying oven 1, The number of the heating surfaces is an important reason to decide the temperature uniformity. The effect of heating on four sides is definitely much better than that of heating on two sides, and the temperature uniformity at various points inside the cavity is higher. 2, The partition comes with its own independent heating tube, which is heated inside the cavity and the heat is conducted through the laminate. This method can heat up quickly and the temperature is more uniform, the disadvantage is that it is slightly more expensive. 3, Part of the heat is conducted by the partition, so increasing the contact area between the partit

 In order to use the biochemical incubator more safely, the following points should be noted 1. If you need to use the device again after stopping for a long time, carefully check the water source, power supply, and all components, and then start the device after confirming no error. 2. In the test stage, the time of opening the chamber door should be reduced as much as possible. 3, the sensor device in the working room, does not suffer from strong impact. 4. During the operation of the equipment, adequate water must be maintained. 5. Non-full-time operators shall not operate at will. 6, the equipment can not troubleshoot their own, please contact the company. 7, because ultraviolet radiation to personnel (especially the eyes) has strong harm, so the operator should minimize exposure to ultraviolet light (contact time should be < 1min). It is recommended that operators wear protective goggles and jackets. Kenton instrument is a powerful manufacturer in China with a history of more

Illumination incubator（ light incubator ）, on the market, there are three types of illumination: the first type is partition illumination, that is, the illumination device is located in the partition, and each layer of the partition with illumination can receive illumination evenly. The second kind of lighting is to bring lighting function to each layer of doors. The third is the top light, that is, on the top of the chamber on the light function, but the KENTON instrument does not recommend this way of light, oh, the reason is very simple, because each partition will place objects, so it will lead to the bottom of the object can not be uniform by the light. When we are in choose and buy, ask ourselves to need above all what kind of illumination means, what illumination means that asks the manufacturer to use next. light incubator

Pay attention to the use of mold incubator : 1. Do not use the instrument when the battery indicator indicates that the power is exhausted. If the device is not used for a long time, please remove the battery and store it. 2. Do not store or use the instrument in high temperature, high humidity, inflammable, explosive, and strong electromagnetic field environments. 3, use a wet cloth or detergent to clean the instrument shell, do not use friction or solvent. 4. When the instrument is wet, it should be dried before storage.

Biochemical incubators are most common in laboratories. Biochemical incubators are widely used, such as seed germination rate determination of compost extract. The extract of the compost sample was extracted, and the germination rate of seeds was measured. According to the literature, a piece of filter paper was spread in a 9cm petri dish, 20 seeds (radish seeds were used) were placed, and 5ml extract was added (I added 10ml). The seeds were cultured in a biochemical incubator at 25 oC for 5 days. Calculate the formula to calculate the speed germination index can be. The ions were removed as a blank control. Calculation formula: F= (A1×A2) /(B1×B2)×100% F: seed germination index; A1: germination rate of seeds cultured infiltrate of compost samples; A2: Root length of seeds cultured infiltrate of compost sample; B1: germination rate of seeds cultured in deionized water; B2: Root length of seeds cultured in deionized water.

 It is completely possible to avoid the phenomenon of vacuum pump oil return caused by improper operation. When there is no need to vacuum, you can pull out the linked rubber hose on the oven body. It should be noted that the vacuum degree is not enough in the drying process, and when the drying is ready to vent, it should be linked back to the vacuum pump. Or replace the oil-free vacuum pump, do not need to worry about this problem. Kenton Instrument professional vacuum drying oven manufacturer, its production of vacuum drying oven widely used in biochemistry, chemical pharmaceuticals, medical and health, agricultural research, environmental protection, and other scientific research applications, used for powder drying, baking, sterilization and disinfection, especially suitable for drying heat sensitivity, easy decomposition, easy oxide Quality, and complex ingredients are quickly dried. vacuum drying oven

The pre-heating technology of the inner liner is to distribute the heating elements evenly in the inner liner to pre-heat the inner wall, then through a heat transfer and fan convection, the more the heating surface is distributed, the better the effect. The circulating air duct is a reasonably designed air transport system combining fan and impeller, air inlet, and outlet, which enables a uniform and constant temperature and humidity in the inner liner. The duct design can be divided into single-sided, double-sided to four-sided circulation convection, the more convection surfaces the better the effect. drying oven:https://en.kentonchina.com/list/Drying-oven.html

What is the difference between the C series and the A and AS series of industrial ovens ?   The "A" series comes standard with an aluminium housing motor, the "C" series with an iron housing motor (the aluminium housing dissipates heat faster and is more durable than the iron housing). "A" standard with high-temperature silicone door seal, "C" asbestos fibre door seal (silicone door seal is more effective and no contamination) "A" standard with progressive locking hinges and thicker hinges. "C" spring-loaded latch (progressive latch for better sealing) "A" has a thicker construction and steel plate material. "A" is made of high-temperature-resistant heating tubes and electrical components of well-known brands, more durable. The AS is the "A" series with a stainless steel liner. Therefore, in terms of configuration, AS is the highest, A is the second, C is the last, of course, the price is also fro

 Anaerobic incubator case: bifidobacterium culture The culture medium formula of bifidobacterium can refer to the national standard of Microbiology test Methods for food hygiene GB/T4789-2003, which is the latest version in 2003, and the culture and identification of bifidobacterium and lactic acid bacteria are newly added. I have made a culture medium with reference to the NATIONAL standard, but it is not BBL. I am sorry that I can not remember the name at that time. The ingredients in the formula are simpler than BBL, and there is no need to do a tomato extraction solution. In addition, the culture needs at least 72 hours, if the experimental conditions are simple, it is best to use pyrogallic acid and anhydrous sodium carbonate reaction method is better, simple operation, good effect. Focal gallic acid and anhydrous sodium carbonate 2 grams each said (says good in advance, standby), to prepare than to use a dish of AGAR (say good medicine can be put on the above, do not mix), and r
