Antech MRF-300 — combined laboratory refrigerator-freezer.
Separate refrigerated and frozen chambers provide two storage environments in one cabinet. Select the refrigerator and freezer volumes independently rather than relying on the model number.
Key features
- Two compressors serve the separate temperature zones.
- The refrigerator uses forced-air cooling and the freezer uses direct cooling.
- The refrigerator defrosts automatically; freezer defrost is manual.
Specification revision
The table describes the model revision in the existing product specification. The current manufacturer web catalogue does not confirm this exact revision. Confirm its data sheet, dimensions, electrical version and included accessories before ordering.

Installation and use
Confirm the electrical version before installation. Rated power is an electrical rating, not daily energy consumption. Storage temperatures and acceptance criteria must follow the material instructions and the facility’s approved procedure. The temperature display does not replace an independent monitoring and alarm response plan.
Frequently asked questions
How should storage capacity be selected?
Consider container dimensions, quantity, rack layout and space needed for air circulation or sample retrieval. Nominal chamber volume is not the same as usable loaded volume.
Does a 0.1 °C display imply 0.1 °C temperature uniformity?
No. Display resolution, stability over time and spatial temperature uniformity describe different properties. Validate the usable storage area through temperature mapping under the agreed protocol.
What should be confirmed before delivery?
Confirm the exact model revision, electrical supply, door arrangement, access route, ventilation clearance, shelves or racks, monitoring and backup provision. List optional accessories separately in the order specification.
Does the alarm battery run the cooling system?
An alarm backup battery in a stationary freezer does not power its compressors. Continued cooling requires suitable backup power or a compatible backup cooling system. Portable freezer run time depends on the actual battery and operating conditions.
