GlowZone Etna

Infrared Loop Sterilizer - using IR-HotSpot Technology


High-Speed Annealing and Sterilizing the Smart Way

Are you looking for a fast, efficient and flameless product to anneal or sterilize

your inoculation loops and delicate micro instruments? Then our electrical

GlowZone Etna should be your first choice.


Smart Infrared Light – Instantly Ready to Work

Specifically focused infrared light generates an IR-HotSpot in which your 

inoculation loop is sterilized at temperatures from 750 to 1000°C after only 

5 to 10 seconds. The GlowZone Etna just needs to be plugged in and will 

be immediately ready to use, without any unnecessary warm-up period. 

Our highly sophisticated annealing tube is based on many years of experience. 

It is made of special quartz glass. The tube is closed at one end preventing 

any risk of contamination with pathogenes. 

The annealing tube can be slid out in a matter of seconds for easy cleaning.


Smart Operation – Touchless Working

GlowZone Etna allows you to fully focus on your core task. Hardly any attention 

is needed for inserting your inoculation loop into the annealing tube – which is 

easily accessible from the front of the flat glass panel.


Smart Design – Outstanding Features

GlowZone Etna comes in an elegant stainless steel housing with a touch safety 

glass control panel designed for extreme laboratory environments with many 

unique features.
