The endotoxin detector developed by our company is a specialized experimental equipment designed specifically for the bacterial endotoxin test method in the 2002 edition of the Chinese Pharmacopoeia. The instrument heats up quickly and can reach a constant reaction temperature of 37 ± 1 ℃ within 10 minutes at room temperature. The temperature has been precisely calibrated before leaving the factory, and users do not need to set it separately. The instrument is equipped with a convenient timing device that supports arbitrary adjustment from 1 to 999 minutes, and is operated through a touch screen. It can simultaneously perform three independent timed cultivation groups to meet diverse experimental process requirements. Its unique dust cover design eliminates the need for sealing the test tube during the reaction process, effectively avoiding the risk of contamination caused by water vapor or water droplets entering the traditional constant temperature water bath, significantly improving operational convenience and experimental accuracy. In addition, the device is equipped with a triple over temperature protection mechanism, supplemented by a buzzer and dual alarm reminders on the touch screen to ensure safe and reliable use; The whole machine has a compact and simple appearance, which is very suitable for daily use in the laboratory.
