Auto-Cascade Ultra-Low Temperature Freezer MDF-86V188E, 408 L (CAT#: STEM-AL2-6936-ZJF)

The Auto-Cascade Ultra-Low Temperature Freezer is designed for long-term storage of biological materials such as blood components, microorganisms, and tissue samples. The model field lists MDF-86V188E, while the product introduction references MDF-86V408E, and both source identifiers are retained. The specification table describes a 408 L cabinet with an auto-cascade refrigeration system. The operating temperature range is stated as -40°C to -86°C. A 7-inch LCD touch display provides access to operating information, alarms, curves, and event records. The source describes VIP insulation with a thermal conductivity of 0.005 W/(m·K) together with multilayer sealing. The cabinet provides storage for 288 two-inch boxes or 28,800 samples in 2 mL vials. USB and RS485 interfaces, a 72-hour power-failure alarm backup, and optional recording or LN2 backup accessories are specified.
