Laboratory Freezer ZLN 85

POL-EKO Laboratory Freezer ZLN 85
The ZLN 85 is a professional 85-liter laboratory freezer providing a reliable temperature range of 2$-25^{circ}C$ to 3$0^{circ}C$.4 Utilizing natural air convection to ensure a stable environment without the risk of sample cross-contamination from high-speed fans, it is ideal for long-term storage in clinical and research labs.5 Managed by the Smart 4.3-inch touchscreen (or the advanced 7-inch Smart PRO), it features integrated data logging via USB/LAN, an “Alarm Bar” for instant status updates, and a robust acid-proof stainless steel interior.6 Its secure door lock and open-door alarm provide critical protection for sensitive temperature-dependent assets.

Description

The POL-EKO ZLN 85 is engineered for laboratories that need high-performance freezing capabilities within a small footprint. Its 85-liter chamber (with a 73-liter working capacity) is perfectly sized for under-bench placement or small workspaces.8 Unlike larger industrial units, the ZLN 85 uses Natural Convection, which relies on gravity-driven air movement.9 This is particularly beneficial for storing fine powders or delicate samples that might be sensitive to the air turbulence caused by fans.+1Intelligent Monitoring and GLP Compliance:The ZLN 85 is available with two controller options to suit different regulatory needs:10Smart Controller (Standard): A 4.3-inch color touchscreen that supports up to 5 user programs.11 It includes a built-in event registry and data logging, accessible via USB and LAN ports.Smart PRO Controller (Optional): Designed for highly regulated environments (e.g., 21 CFR Part 11). It features a larger 7-inch screen, Wi-Fi connectivity, multi-level user management (Admin/User), and expanded memory for up to 40 programs and detailed audit trails.12The Alarm Bar: Both models feature a high-visibility light strip that allows staff to monitor the freezer’s status from a distance?green for stable operation and red for any temperature excursions or alarms.13Industrial Build for Sample Integrity:The interior is crafted from acid-proof stainless steel (DIN 1.4301), ensuring maximum resistance to chemicals and easy decontamination.14 The unit comes standard with two stainless steel wire shelves (expandable to four) and includes a 15$emptyset$20 mm access port on the left wall for external temperature validation probes.16 For security, the solid door is equipped with a physical key lock to prevent unauthorized access to sensitive samples.17+1Primary Applications:Biological Research: Storage of enzymes, DNA/RNA samples, and proteins.18Clinical Labs: Preservation of reagents and medical samples.Chemical Storage: Safe keeping of temperature-sensitive volatile chemicals.Pharma QC: Stability testing and long-term storage of drug components.
