SP Scientific Offers Controlled-Rate Freezer
The Bio-Cool controlled-rate freezer from SP Scientific is suitable for a variety of clinical, commercial and research applications. The freezer does not require expendable liquid nitrogen and avoids the associated pumping, re-filling and storage challenges posed by a cryogenic liquid. The Bio-Cool plugs into a standard electrical outlet and quietly provides low-temperature cooling to either -40C or -80C.
Unlike liquid nitrogen systems, which surround samples with a cold vapour phase, the Bio-Cool immerses samples into a well-circulated cold liquid bath. The circulating liquid enables more efficient heat transfer to the samples and maintains a consistent temperature profile at all locations.
Typical applications that have benefited from the operation of the Bio-Cool include the cryopreservation of human and animal embryos and biological tissue and cell lines. The Bio-Cool comes as standard with a programmable microprocessor controller that enables the programming and storage of up to eight different protocols, each with up to eight distinct segments specifying ramp rate, hold temperature and hold time.
