Product catalog summary
Introduction
Ultra-low temperature (ULT) freezers, such as the Esco Lexicon® models, are crucial for scientific research, providing long-term sample storage at -80°C. These freezers are built with high-quality components and energy-efficient systems to maintain sample integrity.

Key Features
Esco Lexicon® ULT freezers feature 5” thick insulation, independent inner doors, and a triple gasket seal for optimal thermal protection. They are compatible with existing racking systems and include modern refrigeration components for efficiency in extreme conditions.

Construction and Design
Constructed with electrogalvanized steel and antimicrobial powder coating, these freezers ensure a clean lab environment. They include a heated port to prevent icing and a front-mounted condenser filter for easy maintenance.

Performance and Reliability
Esco employs Highly Accelerated Life Testing (HALT) to ensure reliability under extreme conditions. The freezers are designed to outperform competitors in energy consumption and cabinet performance, focusing on superior sample protection and rapid temperature recovery.

Environmental Impact
Using CFC-free and HCFC-free refrigerants, Esco freezers reduce environmental impact, emit less heat, and lower air-conditioning costs, contributing to a reduced carbon footprint.
