Application Profile
At 0 °C to -45 °C (-50 °F), the Scientemp 45-01C covers the *super-cold* band that many enzymes, competent cells, tissue samples and reagents require for stable long-term storage below the reach of a standard -20 °C freezer. Single-stage R-404A mechanical refrigeration reaches these set-points without liquid nitrogen or cascade complexity, and the CAL 9500 digital display provides closed-loop control suited to valuable inventories. The 1 cu ft chest format holds cold well during access because dense cold air settles into the cabinet rather than spilling out when the lid is raised (see cold-storage).
Every Super Cold is customizable: access ports (1", 2" or 4"), ramp/soak control, CO2 and LN2 back-up systems, stainless-steel interior, observation window, and internal heater/fan are brochure-listed options - so the freezer can be specified to a protocol rather than bought off-the-shelf. Choose capacity by sample volume and set-point by the coldest material you store; for -80 °C-class work, step to the Ultra Cold line (see low-temperature-freezer-selection).
