Laboratory Freezer ZLN-T 300

POL-EKO Laboratory Freezer ZLN-T 300The ZLN-T 300 is a professional 310-liter laboratory freezer engineered for high-capacity sub-zero storage and material testing. Operating within a temperature range of $-40^{circ}C$ to $0^{circ}C$, it utilizes natural air convection to ensure a stable, vibration-free environment ideal for delicate biological samples. Managed by the Smart 4.3-inch touchscreen (or the 7-inch Smart PRO), it features advanced data logging, an “Alarm Bar” for status monitoring, and integrated USB/LAN ports. Its acid-proof stainless steel interior and robust construction make it a premier choice for pharmaceutical, medical, and industrial research facilities.

Description

The POL-EKO ZLN-T 300 is the flagship of the ZLN-T series, offering a massive 310-liter internal volume (262-liter working capacity).8 It is specifically built for laboratories that require the storage of large quantities of sensitive materials, such as plasma, vaccines, and chemical reagents, or for conducting large-batch freeze-thaw cycles for building materials like concrete or wood.9+1Natural Convection for Stability:Unlike forced-air systems, the ZLN-T 300 uses Natural Convection.10 This design is critical for laboratories where air turbulence must be avoided to prevent sample dehydration or to ensure a vibration-free environment for ultra-sensitive biological materials. The high-density polyurethane foam insulation ensures that even at 11$-40^{circ}C$, the unit maintains exceptional temperature stability.12+1Smart Control & Data Integrity:To meet the requirements of modern quality management systems (GLP/GMP), the ZLN-T 300 is equipped with the latest controller technology:13Smart Controller: A 4.3-inch touchscreen that manages 5 user programs and logs up to 10,000 data points.14Smart PRO Controller: A 7-inch touchscreen designed for highly regulated environments.15 It offers Wi-Fi connectivity, 40 user programs, and is 21 CFR Part 11 ready with a full audit trail.16+1Security: Both models feature an “Alarm Bar” for immediate visual status checks, a physical door lock, and an open-door alarm to protect valuable inventory.17Robust Industrial Build:The interior is manufactured from acid-proof stainless steel (DIN 1.4301), providing maximum resistance to corrosive substances and ensuring an easy-to-clean environment.18 The unit utilizes the eco-friendly R290 refrigerant (GWP=3), aligning with modern sustainability standards.19 For heavy industrial use, a reinforced version (W) is available, doubling the total unit workload capacity from 80 kg to 160 kg.20+2Primary Applications:Bio-Banking: Long-term storage of large batches of biological samples and research materials.21Pharmaceuticals: Storage of vaccines, enzymes, and reagents at strictly controlled sub-zero temperatures.Civil Engineering: Standardized freeze-resistance testing of concrete, wood, and other building materials.22Clinical Labs: Reliable storage of blood plasma and other human-derived components.23
