Atex Drawer Freezers

The StemAids ATEX Drawer Freezers SFFfg Series Version 740 are spark-free laboratory freezers designed for safe frozen storage of temperature-sensitive substances in closed containers. These upright drawer freezers are suitable for laboratories handling flammable substances, chemical samples, reagents, reference materials, pharmaceutical products, and research samples requiring controlled storage between -9°C and -30°C.

Product Description

The StemAids ATEX Drawer Freezers SFFfg Series Version 740 are based on professional laboratory freezer designs with spark-free interiors and ATEX-compliant construction. They are intended for controlled storage in laboratories where ignition-source reduction inside the storage chamber is important.

The Version 740 range is available in drawer-based configurations such as SFFfg 4001 Var 740 and SFFfg 5501 Var 740. The drawer arrangement helps users organise samples, bottles, packs, boxes, and closed containers efficiently while reducing exposure time during access. These freezers are suitable for chemical laboratories, pharmaceutical labs, industrial QC labs, research institutions, universities, medical laboratories, and controlled storage rooms.

Safety and Handling Guidelines

• Store only materials compatible with the freezer rating, temperature range, and laboratory SOP.
• Use closed, sealed, and chemically compatible containers for stored substances.
• Do not store open volatile liquids, leaking containers, unstable chemicals, or explosive materials unless explicitly permitted by safety documentation.
• Confirm whether the freezer classification matches the hazardous-zone and material-risk requirement before procurement.
• Do not modify electrical parts, thermostat, wiring, drawers, or internal fittings.
• Maintain adequate ventilation around the freezer to prevent overheating.
• Keep the door closed and locked when not in use.
• Use insulated gloves when handling frozen containers.
