The VWR Cooling Thermal Shake Touch Cat. # 89232-904 delivers precise temperature control and reliable shaking performance for demanding laboratory applications. It features a speed range of 300 to 3,000 RPM (300 to 2,200 RPM with standard block) with ±2% accuracy, and temperature control from 17°C below ambient to 100°C. The intuitive 4.3" color LCD touchscreen enables rapid, simultaneous adjustment of speed, temperature, and time, while clearly displaying real-time status. A PID temperature controller maintains accuracy within ± 0.5°C between 20°C and 45°C, and ± 2°C beyond this range. Heating rates up to 5°C per minute and cooling to 3°C ensure efficient operation, complemented by user-programmable memory for automated, multi-step processes. Compact footprint (10.25 x 9.75 x 5.2 in.) optimizes bench space, and advanced safety features - including cool-touch housing, limit controls, and audible alarms - ensure secure, consistent operation.
All of our equipment is fully tested to perform at factory specifications before being shipped.

Thermo Mixer Inspection and Recertification Checklist
- Confirm stability and accuracy of power supply and PCB voltage outputs
- Inspect display integrity, ensuring pixel clarity and replacing any degraded or non-functional elements
- Verify complete functionality and responsiveness of all control buttons, switches, and knobs
- Conduct thorough inspection of internal wiring and all electrical connections for continuity; replace or secure any degraded or substandard components
- Examine block holder platform for alignment, obstructions, or error-inducing irregularities
- Perform detailed inspection of motor bearings, assessing for wear or misalignment, and replace if performance deviates from specifications
- Calibrate rotational speed precisely using a NIST-traceable tachometer for compliance with operational standards
- Calibrate temperature accuracy using a NIST-traceable temperature probe, validating readings across the operational range
- Ensure timer precision by validating functionality and consistency against set parameters
- Conduct a comprehensive cosmetic inspection, verifying all surfaces and external components meet quality standards
