EziLab offers the -65°C Low Temperature Freezer EZL-HF164, a 358 L chest-style deep freezer for lab use that holds any set point from -25 °C to -65 °C in a 1080 by 500 by 660 mm stainless steel well. Direct contact cooling on a CFC-free mixed refrigerant pulls heat through the walls without a fan, draw sits at 480 to 500 W on 220 V, and noise stays near 60 dB. A separate inner lid cuts cold loss on each opening, adjustable racks sort samples, a handle and bottom runners move the 180 kg cabinet, a key lock keeps unauthorized hands out, and the galvanized shell measures 1810 by 895 by 1090 mm. Choose it over the 258 L sibling when intake outgrows a small chest but a 458 L unit would run half empty. Hospitals store plasma and reagents in it, blood banks keep frozen components, disease control centers hold specimens, and research labs bank cell lines. Daily contents include fresh frozen plasma, reagent kits, vaccines, and tissue samples. Retrieval from a 660 mm deep well is slow; ask how the racks lift out, because each long opening drains more cold at -65 °C than at -25 °C. Neighboring chest sizes sit where Laboratory Freezer meets -65°C Freezer.
