Product Overview
Laboratory Infrared Inoculating Loop Sterilizer
A laboratory infrared inoculating loop sterilizer is a rapid sterilization device designed for microbiology laboratories. It is primarily used for the on-demand sterilization of metal inoculation tools, such as inoculating loops, inoculating needles, forceps, and scissors. It can replace a traditional alcohol burner, eliminating the risks associated with open flames while helping reduce cross-contamination. Its flameless design makes sterilization safer and more convenient.
Working Principle
The sterilizer uses an infrared heating element housed inside a specially designed 95 ceramic tube. Once powered on, the heating element rapidly reaches temperatures of 400–900°C. Metal inoculation tools are inserted into the heating tube, where the high temperature can sterilize them in as little as 3 seconds. After removal and cooling, the tools can be used again. This rapid process helps improve laboratory efficiency without the need to wait for an alcohol burner to cool or be relit.

Applications
Laboratory infrared inoculating loop sterilizers are widely used in microbiological culture, cell experiments, environmental monitoring, food testing, pharmaceutical research and development, and university teaching laboratories. They are particularly suitable for sterile operations on laboratory workbenches and inside biological safety cabinets, where inoculation tools require frequent sterilization. The flameless design provides an additional safety advantage in these environments.
Infrared Loop Sterilizer Selection Guide
When selecting a laboratory infrared inoculating loop sterilizer, several factors should be considered. An adjustable temperature range of 400–900°C accommodates different sterilization requirements. Two heating tube sizes are available: Ø14 × 150 mm for standard inoculating loops and needles, and Ø35 × 100 mm for thicker tools such as forceps. The specially designed 95 ceramic tube offers high-temperature resistance and a long service life. Rapid sterilization in as little as 3 seconds helps improve workflow efficiency. Other important considerations include overheat protection, a heat-insulated outer housing to reduce burn risks, and a stable base for safe operation.
