Arabidopsis Chamber - AR-75L2

This Percival® Scientific Arabidopsis Growth Chamber is specifically designed to facilitate the growth of Arabidopsis plants. Provide your plants with more than adequate space for healthy growth by placing them in this chamber. Our growth chambers provide an excellent environment for growing Arabidopsis plants to maturity through use of the unique IntellusUltra™ controller and sturdy construction of the chamber. The controller allows users to monitor and control the conditions within the chamber, like humidity, temperature and CO2, as well as program lighting events. In addition, users can expect superior air flow due to the specifically designed air diffuser.

  • This chamber is frequently used for Arabidopsis thaliana, Brassica sp., lettuce, spinach and other plants with lower light intensity requirements.
  • Many other applications exist for this product

Percival’s IntellusUltra Controller

  • Percival Scientific has built a reputation of providing flexible, customized options for research scientists around the world. We have taken that philosophy to the next level with our improved IntellusUltra Controller. Now choose from the levels of functionality that meet your research needs.

Lighting System

  • Each tier of shelves lighted by SciWhite LEDs enhanced with Red tiles properly spaced for uniform light intensity over entire shelf
  • Intensity programmable up to 350 micromoles/m2/sec at 6” from the tiles
  • Dimmable from 10-100% in 1% increments
  • Programming and control of the lighting is done via IntellusUltra controller


  • Uniform air circulation across each shelf via air diffusers on the rear wall
  • Air circulation inside chamber is from a specifically designed air diffuser (air travels along entire back wall, over the shelves and returns to the ceiling fans through an opening between the light fixtures and the doors)

Cabinet Construction

  • Chambers built in panel sections each consisting of 2” thick urethane insulation
  • Metal interior and exterior surfaces
  • Cam-type fasteners and vinyl gaskets
  • Interior and exterior constructed of 22-gauge electro-zinc plated steel
  • Two 1 1/4” diameter access ports
  • Stainless steel chamber floor equipped with floor drain and hose assembly
  • Chamber cabinet is attached to angle frame base containing heavy duty swivel casters


  • Woodless construction using foam-in-place 2” thick CFC free urethane insulation foam (this is an environmentally friendly foam with global warming potential [GWP] of 0.0 and ozone depletion potential [ODP] of 0.0)


  • Two doors each with an opening of 22.7” x 57.7” providing full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 71.6 cu. ft. with work area of 21.5 sq. ft. provided on two tiers


  • Two tiers of 22-gauge stainless steel with no perforations
  • Each shelf is 27.3”D x 28.4”W
  • Shelves are vertically adjustable in 1/2” increments
  • Maximum growing height is 27.9″ per tier


  • Interior and exterior painted with high reflective, environmentally friendly, high temperature baked white powder coating

Convenience Receptacles

  • Two 115/1/60 convenience receptacles provided inside chamber

Electrical Requirements

  • Consult Geneva Scientific for electrical requirements and amperage draw.

Temperature Range

  • 7-44C (+/- 0.5C) with lights on and 4-44C (+/- 0.5C) with lights off


  • Self-contained air-cooled condensing unit with hot gas bypass system for continuous compressor operation, extended life and close temperature control (this continuous running condensing unit ensures precise temperature control by alternating cycling refrigerant and hot gas to coil; this also prolongs life of compressor, and eliminates risk of ice buildup in coil)
  • Optional outdoor al weather air-cooled condensing unit or self contained water-cooled condensing unit available upon request
  • Solenoid valves have extended stem for quiet and long life operation
  • Heat rejection to the ambient by standard refrigeration system with a air-cooled self-contained condensing unit is 6450 BTU/hr

Temperature Safety Limit Controls

  • Experiment Protection: Adjustable high and low temperature controls, audible alarms, and visual indicators provided
  • Controls shut down all power to chamber, activating alarms (when the temperature returns to the normal range the system will automatically reset)


  • Additive Humidity Control and Dehumidifier with Sensor
  • IntellusUltra Connect
  • Android-Based Touch Screen
  • CO2 Enrichment Package
  • Dry Alarm Contacts
  • Dimmable Lighting
  • LED Lighting in Lieu of Fluorescent Lamps
  • Please contact us for more optional items
