Thermo Scientific 2825 Precision Water Bath Microprocessor Controlled 280 Series 1.5 L

Thermo Scientific Precision Model 2825 Shallow Water Bath (280 Series) – 1.5 L

The Thermo Scientific Precision Model 2825 (280 Series) is a compact, microprocessor-controlled shallow water bath engineered for precise temperature management of smaller sample volumes. Featuring a 1.5-liter fluid capacity, this dependable benchtop instrument is specifically optimized for applications using microcentrifuge tubes, small flasks, and fragile sample vessels. Its space-saving footprint, exceptional thermal uniformity, and easy-to-sanitize seamless chamber make it an asset for clinical, educational, and life science laboratories running routine heating protocols.

Technical Performance & Design

• Microprocessor PID Automation: Driven by an advanced digital PID temperature controller that monitors and stabilizes fluid parameters, delivering a tight uniformity profile of ±0.2°C at 37°C.
• Shallow Chamber Architecture: Designed with a reduced 2-inch chamber depth tailored to maintain stability for small-format tubes, preventing microcentrifuge vials from tipping over or becoming fully submerged.
• Seamless Stainless Steel Interior: The interior chamber is pressed from a single sheet of corrosion-resistant, heavy-gauge stainless steel, completely eliminating welded seams or corners that can trap biological contaminants.
• Over-Temperature Safety Interlocks: Equipped with an independent, user-adjustable thermal safety circuit that automatically cuts power to the heating element in the event of a low-fluid or runaway heating condition.
