QM210WC Precision Constant-Temperature Water Bath

The QM210WC precision water bath serves constant-temperature sample soaking, reagent conditioning and material pre-treatment, achieving uniform, stable bath temperature via high-accuracy closed-loop PID control and a built-in circulation pump.

Low temperature fluctuation and a uniform bath eliminate local temperature drift in soaking conditions, ensuring repeatable constant-temperature pre-treatment and chemical/biological tests.

The stainless-steel bath with a centralized control panel suits constant-temperature soaking and sample preheating in polymer, pharmaceutical, food and chemical labs.

Key Product Features

Closed-loop PID · built-in circulation · stainless bath · uniform temperature field, for constant-temperature sample soaking

High-accuracy PID control

Digital closed-loop PID gives small fluctuation, low overshoot and stable, reproducible temperature.

Built-in circulation pump

Forced liquid circulation makes every point the same temperature, eliminating local differences.

Stainless-steel bath

Corrosion-resistant and easy to clean; suits water and common bath media.

Uniform temperature field

Small top-to-bottom difference keeps multiple specimens under uniform soaking conditions.

Multiple bath sizes

Configured by sample batch and bath depth for different soaking processes.

Constant-Temperature Water Bath
Specimen Soaking Pre-treatment

The QM210WC pairs a high-accuracy PID controller with a built-in circulation pump to give specimens a uniform, stable soaking environment. A consistent bath with small fluctuation prevents drift, and the stainless bath resists corrosion and cleans easily.

From polymer specimen pre-treatment to reagent conditioning - materials often need soak equilibration in constant-temperature water before testing, and bath uniformity directly affects pre-treatment consistency. The built-in pump keeps the whole bath uniform; precise PID control makes it a foundational lab device.

Designed for constant soaking - PID control plus built-in circulation for specimen pre-treatment.
