Astor 900/d – Waterbath for Gerber tests and general uses

The Astor 900/d is a laboratory water bath with digital thermal regulation designed specifically for food industry testing, particularly for Gerber fat analysis. It is used for heating samples, culture media, and other containers.
Key features and uses include:
Gerber Fat Determination: Used in dairy testing to hold butyrometers (fat-analysis tubes) at specific temperatures.
Temperature Range: Operates from 5°C above room temperature up to 100°C.
General Laboratory Use: Suitable for melting and thermostating culture media, samples, and other containers.
Microbiological Applications: The deep stainless steel tank allows for the immersion of bottles and tubes below the water level.
Precision: Features a digital controller, typically with a resolution of 0.1°C.
Construction: Compact design, often featuring a stainless steel tank.

It is also sometimes referred to as a thermostatic bath in lab equipment catalogs, designed for precision in food safety and quality control, particularly in dairy, as indicated in materials relating to the Gerber method.
