Laboratory Freezer ZLN-T 200

POL-EKO Laboratory Freezer ZLN-T 200
The ZLN-T 200 is a high-performance 210-liter laboratory freezer engineered for secure storage and research applications.3 Operating with a temperature range of 4$-40^{circ}C$ to 5$0^{circ}C$, it utilizes natural air convection to provide a stable, vibration-free cooling environment.6 Managed by the Smart 4.3-inch touchscreen (or the 7-inch Smart PRO), it features multi-segment programming, an “Alarm Bar” for status monitoring, and integrated data logging via USB/LAN.7 Its acid-proof stainless steel interior and robust insulation make it a reliable solution for clinical, pharmaceutical, and industrial laboratories.8

Description

The POL-EKO ZLN-T 200 is built for laboratories that require consistent sub-zero temperatures without the air turbulence of forced-air systems. Its 210-liter chamber (180-liter working capacity) is ideal for storing easily decomposing materials, biological samples, and pre-freezing tasks.9 The Natural Convection system ensures a quiet operating environment and prevents the dehydration of samples that can occur with high-velocity airflow.Intelligent Monitoring & Data Security:The ZLN-T 200 is equipped with advanced controllers to ensure sample integrity:10Smart Controller (Standard): Features a 4.3-inch color touchscreen, 5 user programs, and a built-in event registry.11Smart PRO Controller (Optional): Designed for strictly regulated environments, providing a 7-inch touchscreen, 40 user programs, and Wi-Fi connectivity.12 It is 21 CFR Part 11 ready with a full audit trail.Visual Safety: The signature “Alarm Bar” light strip allows you to check the freezer’s status (Cooling, Stable, or Alarm) from across the room.13Industrial Build and Safety:The interior is crafted from acid-proof stainless steel (DIN 1.4301) for maximum chemical resistance and easy decontamination.14 The unit uses eco-friendly R290 refrigerant and features high-density polyurethane foam insulation to maintain temperature even during short power outages.15 Safety features include an open-door alarm, a physical door lock, and an access port (16$emptyset$20 mm) for external temperature validation probes.17+2Primary Applications:Life Sciences: Long-term storage of samples, biological materials, and plasma.18Pharmaceutical: Storage of vaccines and temperature-sensitive chemical reagents.19Industrial Testing: Frost resistance tests for building materials like concrete and wood.20Medical: Pre-freezing biological components before specialized processing.21
