Hot air disinfection box (dry heat disinfection box) - LCD display

Scope of application

Using high temperature and dry heat to oxidize microorganisms, denature proteins, and dielectric concentration, causing poisoning

use. It mainly destroys cell protoplasm through oxidation and causes microorganisms to die, so

All microorganisms can be killed within a certain heating time.

Structural features

>Accurate: High-precision microcomputer LCD display temperature controller, accurate and reliable temperature control.

>Rapid: The heat rises quickly, forced convection, the dry and hot air passes directly through the heated object, drying, and disinfection time is significantly shortened.

>Safety: Adopt two sets of overtemperature protection systems. Automatic interruption is automatically achieved after exceeding the limit to ensure the safety of personnel and instruments.

>Convenient: It can be controlled regularly, and the partition can be freely moved and convenient for cleaning in the box, making it convenient for operators.
