GRAM BioPlus ER600D: a high-precision storage solution for sensitive biological materials
The GRAM BioPlus ER600D is a laboratory refrigeration unit designed specifically for the safe storage of extremely sensitive biomaterials. Its design ensures stable internal conditions, which is essential when even slight variations in temperature or humidity can alter stored samples. With an adjustable temperature range from +20°C to -2°C, this unit is particularly suitable for environments where strict control of climatic parameters is required, such as research laboratories, hospitals and pharmaceutical centres.
At the heart of the system is the intelligent electronic "Gram Control Unit", which not only monitors the temperature precisely, but also allows individual programming of audible and visual alarms, with alert recording and offset function. A potential-free output (dry contact) also allows the alarms to be connected to external monitoring systems, enhancing the safety of the installation. The BioPlus ER600D is therefore designed to minimise the risk of costly losses due to environmental failures.
The integrated BioLine air distribution system ensures even temperature distribution inside the chamber, keeping variations from one point to another in the storage volume to a minimum. Combined with 60 mm thick polyurethane insulation and no HFC propellants, the BioPlus ER600D combines high thermal efficiency with environmental friendliness. The refrigerant used, R290, offers excellent energy efficiency while meeting the most stringent environmental standards.
The cabinet is available in stainless steel or white lacquered steel finish, with a solid or glass door depending on access and visibility requirements. Its gross volume of 600 litres, with a net volume of 432 litres, allows a large quantity of samples to be stored in a flexible configuration consisting of 24 shelves or 12 modular drawers. This modular system is ideal for adapting the space to different formats of containers, tubes, vials or bags.
Ease of use is also at the heart of the design. The unit is equipped with a 24.5 mm access port for the integration of external monitoring probes. The automatic defrost function with condensation re-evaporation limits manual intervention and reduces maintenance. The noise level is kept to 46 dB(A), ensuring a quiet working environment. The cabinet is mounted on feet (or optional castors) for easy positioning in any type of laboratory.
The BioPlus ER600D complies with ATEX Directive Category 3, Zone 2, which allows it to be installed in environments where explosive atmospheres may occasionally be present. This compliance, both internal and external, underlines GRAM's commitment to safety and reliability.
