Gas chromatograph refers to a chromatographic analysis instrument that uses gas as the mobile phase. Mainly used in: environmental protection, food fermentation, petroleum processing, organic chemistry and other industries analysis and research.
The 721\722\722N\722S visible spectrophotometer is an economical analytical instrument with optional RS232 interface output. The excellent photometric accuracy is higher than that of the general instruments of the same grade. Widely used in testing, food, petrochemical industry, environmental protection and monitoring and many other fields.
Nitrogen blowers are mainly used for the concentration or preparation of large batches of samples. Through microcomputer control technology, high-purity aluminum material is used as heating medium to achieve more accurate temperature control and wide temperature control range. The working principle is that by blowing nitrogen gas into the surface of the heated sample, the solvent in the sample is quickly evaporated and separated, so as to achieve the purpose of anaerobic concentration of the sample and keep the sample more pure. Features 1. The blowing needles are independent of each other to avoid cross contamination. 2. The height of the air cavity can be adjusted, and the standard air needle length is 150mm. 3. The nitrogen blower has 12 airway control switches, which does not waste gas. 4. When concentrating toxic solvents, the entire system can be placed in a fume hood. 5. Built-in over-temperature protection device, automatic fault detection and alarm function. 6. LED display, temperature synchronous display, time decrement display, simple and convenient operation.
1. Using new electronic circuits, equipped with high-speed CPU and special chips, it can quickly obtain accurate weighing results. 2. Multi-level digital filtering and compensation technology to optimize the weighing performance of the balance under different weighing conditions. 3. Dynamic temperature compensation, real-time correction of the impact of ambient temperature fluctuations on the measurement results. 4. Green and environmentally friendly design, using environmentally friendly and safe materials, the power consumption is reduced by 50%, and the standby power consumption is 1W. 5. The standard five-sided glass windshield and anti-static base plate design can effectively avoid the influence of static electricity on the weighing results. 6. The clear and bright digital backlit display makes it easy to read in all working environments. 7. Front level adjustment feet and level indicator are convenient to observe and adjust the level, and ensure the level state at all times. 8. The large tare key is designed to facilitate the user's weighing operation. 9. SmartTrac dynamic graphic display, which directly displays the weighing range used by the balance. 10, 1/10d readability reduction function, quickly obtain stable weighing results. 11. Key-triggered automatic internal or external weight calibration to ensure accurate weighing results are always obtained. 12. The balance frame is equipped with a plastic protective cover as standard to avoid corrosion of scattered samples and damage to the balance surface. 13. Customer fine-tuning function (ADJ.CF), which enables you to adjust the built-in calibration weight value with your own calibration weight. 14. Hereinafter referred to as the hook design, to meet the special application requirements of customers. 15. Built-in RS232 communication interface, which is convenient to connect peripheral devices such as printers and computers.
MJ80/150/250 mold incubator is a test equipment suitable for cultivating mold and other eukaryotes. It is mainly used for cultivating and planting. Corresponding temperature and humidity are set in a closed space, which is used for artificially accelerating the propagation of mold and evaluating electrical and electronic products. Anti-mildew ability and mildew process. 1. Product structure This product is a vertical structure, the shell is made of high-quality cold-rolled steel plate, and the surface is electrostatically sprayed. The studio is made of mirror stainless steel plate.
