Description
The ST 3 / ZLN 85 is a premier “Mixed” multi-chamber device from POL-EKO, engineered to streamline laboratory workflows by combining a large-volume incubator with a dedicated deep-freeze compartment. By stacking a 200-liter cooled incubator directly above an 85-liter freezer, this unit offers a total capacity of 285 liters while occupying only 60 cm of floor width. It is an ideal choice for biotechnology, pharmaceutical, and clinical labs where samples must be moved frequently between frozen storage and controlled incubation.

Independent Dual-Zone Performance The unit operates as two completely distinct thermostatic environments:
Upper Chamber (ST 3): A 200-liter cooled incubator using forced air convection for rapid recovery and high temperature uniformity. It is optimized for BOD5 testing, seedling germination, and microbiological studies.
Lower Chamber (ZLN 85): An 85-liter laboratory freezer with natural air convection, designed for stable storage of vaccines, enzymes, and other sensitive biological materials at temperatures as low as -25?C.
Advanced Control and Connectivity Both chambers are equipped with their own dedicated microprocessor PID controllers, available in two tiers:
Smart Controller: Features a 4.3-inch color touch screen, 5 user programs, and integrated LAN/USB ports for data logging.
Smart PRO Controller: Offers a premium 7-inch color touch screen with Wi-Fi, multi-level user management (Admin/User), and 40-segment programming for complex environmental cycles. Both interfaces are glove-compatible and include the signature Alarm Bar for instant visual status monitoring of each independent zone.
