Fisher Scientific Thermal Mixer
The Fisher Scientific Thermal Mixer (Cat. #: 270600F) is a heating/cooling thermal mixer with digital microprocessor control and adjustable speed to provide gentle or vigorous mixing action. With a wide temperature range of 18°C below ambient to 99°C, the thermal mixer allows for greater functionality in the life science laboratory. The Fisher Scientific Thermal Mixer also features programmable control for standard operation, on/off mixing function, and on/off mixing function with heat/cool programmability, including up to ten programmable settings per set function. The Fisher Scientific Thermal Mixer is in excellent condition, and all of our equipment is fully tested to perform at factory specifications before being shipped.
The Fisher Scientific Thermal Mixer includes:
- > 1.5/2.0 ml Block
- > Operator's Manual
- > Power Cord
- > Full 180 Day Parts and Labor Warranty

- 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
