-86°C Ultra-Low Temperature Freezers 28L Lab Cryogenic Freezer 123 °F Samples Flash Freezer for Laboratory Samples Storage (28L)

Description

Product Overview

The LABFENG 28L Ultra Low Temperature Freezer is engineered to meet the demanding requirements of modern laboratories, research facilities, and biotechnological environments where precise temperature control is essential. Constructed from high‑grade stainless steel, the unit offers a robust top‑door configuration that simplifies loading and unloading of sample trays while maintaining a sealed environment. The interior is insulated with a high‑density polyurethane foam layer, minimizing thermal loss and ensuring consistent -86°C performance even during frequent door openings. A microcomputer control system delivers temperature regulation with an accuracy of 0.1 °C, and the integrated LED display provides real‑time readouts for quick monitoring. Certified by Energy Star, the freezer balances high performance with reduced power consumption, making it an economical choice for continuous operation. The freestanding design occupies a compact footprint of 50 × 50 × 50 inches, fitting comfortably into standard laboratory spaces while offering three adjustable stainless steel shelves for flexible storage configurations. Additional safety features include an intelligent temperature alarm that triggers both audible and visual alerts if the set temperature range is exceeded, protecting valuable specimens from accidental thawing.

Usage

Designed for versatility, this ultra‑low temperature freezer serves a broad spectrum of applications. In academic research labs, it preserves cell cultures, enzymes, and reagents that require stable sub‑zero conditions. Pharmaceutical development teams rely on the unit to store vaccine candidates, biologics, and critical reference standards. Clinical diagnostics facilities use the freezer for long‑term storage of patient samples, ensuring integrity for future analysis. The freezer also excels in industrial settings such as food safety testing, where it safeguards perishable test materials, and in environmental monitoring stations that need to retain collected specimens over extended periods. Its top‑door access and ergonomic handle design make it suitable for high‑traffic environments, while the low vibration operation protects delicate samples from mechanical stress. The unit’s 110 V power requirement aligns with typical laboratory infrastructure, and its Energy Star rating helps facilities meet sustainability goals without compromising performance.
