Vintage PolyScience Model 900 laboratory refrigerated/heated circulating bath in good working condition.

Cooling and heating functions have both been tested and confirmed operational. The included listing video clearly demonstrates:

• active cooling operation
• heating operation
• circulation system functioning

This unit is designed for precise temperature control of liquids and can be used as:

• laboratory circulating bath
• recirculating chiller
• temperature-controlled immersion bath
• external cooling/heating source for scientific equipment

Common applications include:

• laboratory research
• chemical processing
• electronics testing
• calibration systems
• laser cooling
• industrial process temperature control
• viscosity and materials testing

The unit includes external circulation capability via hose fittings, allowing it to circulate cooled or heated fluid through external equipment.

Interesting use for PC enthusiasts / extreme overclocking:
This type of refrigerated circulator can also be adapted for chilled liquid cooling systems used in high-performance computer overclocking applications. The system may be used to cool immersion fluid or recirculating coolant for sub-ambient CPU/GPU cooling setups. Compared to standard PC water cooling, laboratory chillers like this provide much more stable and controllable coolant temperatures.

Possible enthusiast applications:

• immersion cooling experiments
• chilled water loops
• sub-ambient liquid cooling
• GPU/CPU benchmark systems
• retro and modern extreme overclocking projects

Please note:
Sub-ambient cooling can create condensation and requires proper insulation and experience when used for computer cooling applications.

Cosmetic condition:
Shows normal cosmetic wear consistent with age and laboratory use. Please review all photos carefully for condition details.

Included:

• PolyScience Model 900 main unit only
• exactly as shown

Sold as used laboratory equipment.

Shipping:
This is a heavy and sensitive instrument. It will be packed carefully for safe transport.
