Refurbishment and Testing Process
At American Instrument Exchange, each refurbished dry block heater is inspected and evaluated by our technicians prior to shipment. Testing procedures may include temperature verification throughout the operating range, controller functionality testing, timer verification, calibration assessment, display operation, over-temperature safety testing, electrical safety inspection, and general operational evaluation. Components showing excessive wear are serviced or replaced as needed to help ensure dependable laboratory performance. Final cleaning and inspection are completed before packaging and shipment.
Shipping and Installation Considerations
The Thermo Scientific 88870003 should be installed on a stable, level laboratory bench with adequate ventilation around the unit. Buyers should verify electrical compatibility before installation and select interchangeable aluminum heating blocks appropriate for their sample vessels. Because heating blocks are removable, they should be installed securely before operation to ensure proper heat transfer and temperature accuracy. The instrument is carefully packaged to protect the controller, heating assembly, and electronics during shipment.
Related Laboratory Equipment
Laboratories purchasing dry block heaters often also require biosafety cabinets, PCR thermal cyclers, centrifuges, water baths, incubators, laboratory refrigerators, and analytical balances. American Instrument Exchange offers a wide selection of refurbished laboratory equipment to support molecular biology, pharmaceutical research, clinical diagnostics, biotechnology, and analytical laboratory workflows.
