Environmental Chambers . Chamber – 821L Ref. RH 220V

Thermo Scientific™ Environmental Chambers increase the functionality of your lab. The 311L to 821L units meet ICH, FDA, TAPPI, DIN12880 and national testing standards and are built to last. Use them for your applications requiring temperature control above or below ambient, humidity control, and CO2 on option. This series of environmental chambers are ideal for drug stability studies, shelf life testing for packaged products, controlled temperature storage, and insect and other large-scale biological research and can be tailored to your application with many options.

Environmental Chambers . Chamber - 821L Ref. RH 220V

  • 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
  • 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
