High temperature box muffle furnace is one of the laboratory equipments used in laboratories, industrial and mining enterprises and scientific research institutes for element analysis and determination as well as heat treatment and heating of small steel parts such as quenching, annealing and tempering. High temperature furnace can also be used for sintering, dissolving and analysis of metals and ceramics. 1. When the muffle oven is used again after the first use or long-term shutdown, the oven must be baked first. The baking time should be four hours at room temperature of 200 and three hours from 200 to 600 respectively. When in use, the furnace temperature shall not exceed the rated temperature in order to avoid burning down the electric heating elements. Statically pouring various liquids and soluble metals into the furnace, the muffle furnace is recommended to work below the maximum temperature of 50 C, so as to maintain a longer service life of the furnace wire. 2.

There are two types of purification workbenches: horizontal flow and vertical flow. According to the functions used, they can be divided into desk type and vertical type, single-sided (double-sided) and double-sided (double-sided). It is one of the indispensable basic equipments for biotechnology research and experiment. It is mainly used in medical and health, colleges and universities and other industries for air purification in operating areas. The air filter is the core equipment and an important component of the air purification system for the purification workbench. The resistance of the filter to air will increase with the increase of dust deposit. When the filter accumulates too much dust and the resistance is too high, the air flow through the filter will decrease, or the filter will be partially penetrated, so when the resistance of the filter increases to a certain extent, the filter will be discarded. Therefore, when using the purification workbench, the filter needs to be

Biosafety cabinet is the main clean equipment of biological experiment. It can effectively prevent the harm of toxic and harmful air suspended particles to the experimental operators, so as to ensure the safety of operators and environment in the process of experiment. When carrying out some high-risk experiments, biosafety cabinets need to be operated according to the specified instructions. Otherwise, it will lead to unsatisfactory use effect or danger, thus threatening the personal safety of operators and environmental pollution. Generally speaking, our operators need to read the instructions for the use of biosafety cabinets in detail before using biosafety cabinets. Only in this way can we ensure that there will be no errors in the use process, if the experienced operator teaches, it will greatly increase the safety of the experiment. Secondly, when choosing biosafety cabinets, we also need to choose products with national security certification. If there are a variety of certific

Digital thermostat water bath pot is one of the common laboratory equipments used for constant temperature auxiliary heating in medical and health, medical colleges, laboratory tests, industrial and mining enterprises and scientific research units. Digital display constant temperature water bath pot uses temperature sensor to convert the water temperature into resistance value. After amplification and comparison of the integrated macro-controller, the output control signal can effectively control the average heating power of the heating tube, so that the water in the tank can keep constant temperature, which can be displayed once through high-precision temperature control. The use method of constant temperature water bath pot is very simple. As long as it is regularly maintained in peacetime, it can not only maintain work efficiency, but also improve service life. 1. It is better to use purified water in a constant temperature water bath to avoid subsequent scaling. 2. When water is in

As we all know, the constant temperature and humidity box is not used directly after purchase, but can be used only after maintenance and cleaning, so as to remove impurities in the box, but also to check the normal use of equipment. Because the equipment will inevitably have some vibration in the process of transportation, which will lead to the impact of some parts inside the equipment, so it is necessary to test and test the equipment after receiving the equipment. And after we receive the constant temperature and humidity box, how should we detect it and where should we detect it? Kangheng Instrument Laboratory Equipment Manufacturer tells you that you can test the following three points. 1. Keep the inside and outside of the constant temperature and humidity test box clean: The test box needs to be cleaned up before operation. The laboratory also needs to be cleaned regularly. The dust in the room can be cleaned by vacuum cleaner. In addition, the outside of the box body also need

A vacuum drying oven is called a vacuum drying chamber because of its vacuum pump. It can reduce the boiling point of liquid to be expelled in a vacuum environment. It is very practical for thermal-sensitive substances. Some powder or granular samples can also shorten the drying time when using a vacuum drying chamber. A vacuum drying chamber can completely eliminate the possibility of thermal explosion of oxides in vacuum environment. Compared with an ordinary drying chamber relying on air circulation, powder samples will not be blown away during drying. But what should we do when air leakage happens in the process of using? In fact, it's not difficult to solve. Kangheng Instrument Laboratory Equipment Manufacturer tells you how to do it. When the vacuum degree of the drying box reaches the required vacuum degree, the vacuum degree decreases in a short time. After replacing the new vacuum valve and electronic tube, it is still the case. So how to check the remaining? It is difficu

Carbon dioxide incubator can create a simulated environment similar to natural growth in incubator, provide stable temperature, professional infrared CO2 sensor, so that the detection of CO2 concentration is more accurate. An advanced instrument suitable for cell, tissue and bacterial culture is the essential key equipment for immunology, oncology, genetics and bioengineering. It is widely used in the research and production of microorganisms, Agricultural Sciences and drugs. Because the CO2 incubator is often in contact with water and drinking gas, impurities in the gas may enter the gas pipeline, resulting in the machine can not work properly. At this time, we need to do some routine maintenance work. The following are several maintenance points put forward by Kangheng Instrument Laboratory Equipment Manufacturer: 1. Check the water level of the water jacket regularly and add water when the water level is low. 2. Regular inspection of carbon dioxide cylinders should not allow carbon
