Water Bath Shaker - Reciprocating Shaking Water Bath - 31 L, 20-180 rpm - RT to 100°C, ±0.1°C

The Master Science Reciprocating Water Bath Shaker shakes and mixes samples steadily while holding them at a constant temperature. It is used for cell culture, hybridization, molecular biology assays and other incubations that need both gentle agitation and precise warming.

The 31 L mirror stainless steel tank operates from ambient to 100°C with ±0.1°C stability, and a crankshaft and double-link drive moves the basket back and forth at 20 to 180 rpm with a 16 or 24 mm stroke. A large backlit LCD and PID control make the Master Science Reciprocating Water Bath Shaker easy to set, and it can also be used as a plain water bath.

Problems the Master Science Reciprocating Water Bath Shaker Solves

Separate shakers and baths waste space and give less control. The Master Science Reciprocating Water Bath Shaker helps with:

• Temperature drift during incubation: PID control keeps ±0.1°C stability.
• Splashing at start-up: Slow-start shaking protects flask contents.
• Lost runs after power cuts: Settings are remembered and operation resumes.
• Low water damage: Water level protection safeguards the heater.
