Thermo Scientific Precision Water Bath 12 L Microprocessor Controlled 280 Series

Thermo Scientific Precision Model 2837 (280 Series) 12-Liter Microprocessor-Controlled Water Bath

The Thermo Scientific Precision Model 2837 is a 12-liter, general-purpose laboratory water bath designed for precise thermal incubation, sample warming, and temperature maintenance across biological, clinical, and biopharmaceutical workflows. Part of the trusted 280 Series line, the Model 2837 utilizes a microprocessor-controlled digital system to deliver high thermal uniformity and stability ranging from ambient plus 5 degrees C up to 99 to 100 degrees C. Constructed with a seamless, corrosion-resistant 304 stainless steel interior chamber and a rugged epoxy-coated cold-rolled steel exterior, this water bath eliminates internal hotspots and resists chemical spills. The unit incorporates dynamic temperature control, over-temperature safety protection, and an easy-to-clean interior reservoir with a perimeter gable cover support ledge, ensuring dependable operation for sensitive cell culture media preparation, enzyme reactions, and analytical sample warming.

Technical Performance & Structural Attributes

• Microprocessor Digital Controller: Provides precise temperature calibration and LED digital readout for clear monitoring of setpoint and actual bath temperatures.
• Seamless Stainless Steel Chamber: Deep-drawn 304 stainless steel interior chamber features rounded corners to prevent corrosion, scale accumulation, and bacterial harborages.
• Uniform Heating Element Layout: Concealed heating elements located beneath the chamber floor prevent direct chemical contact while maintaining homogeneous thermal convection.
• Dual Thermostat Safety System: Independent primary microprocessor controller paired with a secondary safety limit sensor protects samples from thermal overshoot and dry-burn conditions.
• Durable Chemical-Resistant Exterior: Tough powder-coated exterior finish resists harsh laboratory disinfectants, organic solvent splashes, and physical wear.
