Air bath shakers (also known as thermostatic shakers, constant temperature shakers, or benchtop air bath shakers) are laboratory instruments that combine temperature-controlled incubation with mechanical agitation. They are used to cultivate microorganisms, mix samples, and conduct biochemical reactions under controlled temperature conditions.
Unlike water bath shakers, which use heated water for temperature control, air bath shakers use forced air circulation to maintain temperature, eliminating the need for water maintenance and reducing contamination risks. Hawach air bath shakers offer orbital, reciprocating, or combined shaking modes with precise temperature control from ambient +5°C to 60°C and speed control from 40 to 300 rpm.
Air bath shakers operate by combining temperature-controlled air circulation with mechanical agitation. An electric heating element warms the air inside the chamber, which is circulated by a fan to maintain uniform temperature. Simultaneously, an electronically controlled drive system moves the platform in orbital, reciprocating, or combined motion patterns.
