Laboratory Freezer ZLW-T 300

POL-EKO Laboratory Freezer ZLW-T 300 The ZLW-T 300 is a professional 300-liter laboratory freezer designed for the secure storage of biological samples, reagents, and chemicals at temperatures down to -25?C. Utilizing forced air convection (fan-assisted cooling), it ensures rapid temperature recovery after door openings and excellent temperature uniformity throughout the chamber. Equipped with the Smart 4.3-inch color touchscreen controller, it features integrated data logging via USB/LAN, a robust alarm system, and a high-quality acid-proof stainless steel interior. It is an ideal solution for high-throughput medical, pharmaceutical, and research laboratories.

Description

The POL-EKO ZLW-T 300 is engineered for demanding laboratory environments where large volumes of samples must be kept under strict thermal conditions. Its 300-liter internal capacity provides a generous workspace, accommodating large batches of reagents or biological materials. The “W” in its designation indicates Forced Air Convection, which is a critical feature for high-traffic labs. By using a fan to circulate air, the freezer eliminates thermal gradients and ensures that the internal temperature returns to the setpoint almost immediately after the door is closed.Advanced Control and Sample Security:Managed by the Smart controller, the ZLW-T 300 prioritizes sample integrity and regulatory compliance:Real-Time Monitoring: The 4.3-inch touchscreen provides clear visibility of the current temperature and history. The “Alarm Bar” offers instant status updates?green for stable operation, and red for alerts such as temperature deviations or power failures.Traceability: Integrated USB and LAN ports allow for seamless export of data logs and event registries, making it fully ready for GLP/GMP audits.3Safety & Access: The unit includes an independent over-temperature protection system and a physical door lock to prevent unauthorized access to valuable or hazardous materials.Durable and Ergonomic Design:The interior is crafted from acid-proof stainless steel (DIN 1.4301), ensuring maximum chemical resistance and ease of sterilization. The unit is designed with thick polyurethane foam insulation to maximize energy efficiency. For specialized needs, the ZLW-T 300 can be customized with a door with a viewing window, internal LED lighting, or a dedicated access port ($emptyset$30 mm) for external validation sensors.Primary Applications:Life Sciences: Storage of enzymes, sensitive DNA/RNA samples, and proteins.Clinical Facilities: Large-scale preservation of plasma, serum, and other blood products.Pharmaceuticals: Storage of raw materials and stability testing of finished products.Industrial Research: Housing chemical reagents and materials requiring a stable -25?C environment.
