Precise Temperature Control from -10°C to 100°C: Refrigerated Bath Circulator DWR110
Maintain exact thermal conditions for demanding laboratory applications with the Refrigerated Bath Circulator DWR110—a high-performance, recirculating chiller-heater engineered for viscosity testing, chemical reactions, sample cooling, distillation, and material stability studies. Combining active refrigeration with heating capability, the DWR110 delivers exceptional temperature stability (±0.05°C) across a wide range of –10°C to 100°C, making it ideal for ASTM, ISO, and pharmacopeial methods requiring precise thermal control.
Engineered for Stability, Uniformity, and Laboratory Integration
The DWR110 Refrigerated Bath Circulator features a hermetically sealed compressor, PID temperature control, and a high-flow centrifugal pump (up to 15 L/min) that ensures consistent temperature delivery through an external circuit or internal stainless-steel reservoir (10–20 L capacity). Its corrosion-resistant stainless-steel bath and PTFE-coated coils support use with water, glycol mixtures, and mild solvents, while the digital interface enables programmable ramps, holds, and remote monitoring.
- Temperature Range: –10°C to 100°C – Covers sub-ambient cooling to high-temperature heating in one unit.
- High Stability: ±0.05°C – Meets requirements for kinematic viscosity (ASTM D445), stability chambers, and reaction control.
- Circulation Flow: Up to 15 L/min at 0.8 bar – Supports external jackets, viscometer baths, or reactor coils.
- Digital PID Controller with Timer – 10-program memory, ramp/soak profiles, and RS232/USB connectivity.
- Low Fluid Volume Design – Minimizes coolant use and speeds thermal response.
- Compact Benchtop Footprint with Casters – Easy to move; includes drain port and overheat protection.
Trusted in Quality Control, R&D, and Standardized Testing
From conditioning lubricants before viscosity testing and cooling exothermic reactions to maintaining sample integrity in chromatography or simulating environmental conditions, the DWR110 ensures repeatability and compliance. Its ability to both heat and cool eliminates the need for separate water baths and chillers—saving space, cost, and setup time.
Whether you’re running ASTM D445 viscosity tests or developing temperature-sensitive formulations, the Refrigerated Bath Circulator DWR110 delivers the precision, reliability, and flexibility your lab requires.
Control temperature. Ensure reproducibility. Accelerate your workflow.
