Features
  • 0° to 60°C (32° to 140°F) temperature range that can be set in 0.1°C increments
  • Optimum uniformity and a wide temperature range allow for easy compliance with regulatory requirements
  • Rugged construction and durable shelving provide for long life
  • Customizable options are available to tailor this series to your specific applications
  • We confidently back our environmental chambers with a full two year parts and labor warranty
Durability
  • Exterior cabinet is 18 gauge cold-rolled steel, powder coated for durability and a high quality appearance that resists scratches and chipping
  • 51mm (2.0 in.) thick, non-CFC, foamed-in-place polyurethane cabinet insulation provides maximum product thermal protection and increased rigidity for reliable daily use
  • Phenolic-coated evaporator protects against corrosive by-products or agents in the chamber atmosphere (e.g., secretions from insects such as flies), ensuring long life
  • Solid, stainless steel interior is more durable and corrosion-resistant than plastic or painted metal, ensuring long life and minimizing equipment costs
  • Heavy-duty, solid, stainless steel shelves are easy-to-clean, saving time and effort; more corrosion-resistant than coated wire shelves for long life; and adjustable for convenience
  • 821L models include 6 shelves that are adjustable on 76mm (3 in.) centers
  • 311L model includes 3 shelves that are adjustable on 51mm (2 in.) centers
  • Reinforced floor/shelf components for 821L models are available so you can use shakers, cell rollers, or other heavy equipment or product loads inside the chamber to meet a variety of applications
    • Swivel, locking casters ensure easy mobility during installation and cleaning. Leveling feet provide stability and added safety in the lab.
Horizontal Laminar Airflow System
  • Directed airflow system promotes ideal growth environment by distributing airflow uniformly throughout the chamber; versus a horizontal airflow system which does not evenly distribute throughout the shelves of the chamber.
Factory-installed options (ordered separately) include:
  • Choice of access ports for inserting data logging sensors or cables
  • Convenience receptacles to run electrical devices in chamber
  • Choice of chart recorders for data logging
  • Choice of data outputs for monitoring/alarm (3962 model only)
  • Infrared CO2 Control Package for control of a CO2 environment.
  • Heatless dryer for low humidity conditions
  • Stainless steel glass door cover for light sensitive applications
  • Door options include door lock, left-hand door, and Lexan™ inner door
  • Choice of shaker support systems provides system safety
  • Temperature mapping and calibration certificates–customized
