Laboratory Freezer ZLW-T 200

POL-EKO Laboratory Freezer ZLW-T 200
The ZLW-T 200 is a 210-liter forced-air freezer providing a temperature range of 2$-40^{circ}C$ to 3$0^{circ}C$.4 Engineered for situations requiring frequent door openings and rapid pull-down times, its internal fan eliminates thermal layers to keep samples safe.5 Managed by the Smart 4.3-inch touchscreen (or the 7-inch Smart PRO), it features integrated data logging via USB/LAN, an “Alarm Bar” for instant visual status updates, and a heavy-duty acid-proof stainless steel interior.6 With its standard castors and secure door lock, it is a mobile and secure solution for plasma storage, biological research, and material frost-resistance testing.

Description

The POL-EKO ZLW-T 200 is the ideal choice for busy laboratories where temperature recovery speed is critical.8 While natural convection freezers can experience temperature stratification, the ZLW-T 200 uses a high-efficiency fan to actively circulate air.9 This forced convection significantly improves temperature stability and uniformity throughout the chamber, making it much more resilient during frequent sample retrievals.10+1Advanced Control and Regulatory Compliance:The unit is available in two controller tiers to meet specific facility requirements:11Smart Controller (Standard): Features a 4.3-inch color touchscreen, 5 user programs, and a built-in event registry for reliable daily operation.12Smart PRO Controller (Optional): Designed for strictly regulated environments (e.g., 21 CFR Part 11). It offers a 7-inch touchscreen, Wi-Fi connectivity, multi-level user management (Admin/User), and an expanded memory for up to 40 programs and detailed audit trails.13Status Monitoring: The signature “Alarm Bar” allows for immediate visual confirmation of the unit’s status from across the lab?green for stable operation, blue for cooling, and red for alarms.14Industrial-Grade Build and Safety:The interior is crafted from acid-proof stainless steel (DIN 1.4301), ensuring long-term resistance to chemicals and moisture.15 The unit is mounted on castors for easy mobility and includes a standard door lock and an open-door alarm.16 For specialized validation, a 17$emptyset$20 mm access port on the left wall allows for the introduction of external temperature sensors.18 Safety is further supported by optional Class 3.2 over-temperature protection according to DIN 12880.19+3Primary Applications:Life Sciences: Long-term storage of enzymes, DNA/RNA, and protein samples.Clinical Labs: Reliable preservation of blood plasma and medical reagents.20Industrial Testing: Freeze-resistance tests for building materials (concrete, wood, etc.).21Pharmaceuticals: Pre-freezing and stability testing under controlled sub-zero conditions.

Specifications

POL-EKO Laboratory Freezer ZLW-T 200 Full Specifications

The ZLW-T 200 differs from the ZLN-T series by utilizing forced air convection (fan-assisted cooling).1 This ensures better temperature uniformity throughout the chamber and faster recovery times after the door is opened.2
