Arabidopsis Chamber - AR-36L2

The Percival® Scientific Arabidopsis Chamber is specifically designed to facilitate the growth of Arabidopsis plants. This chamber meets all your requirements for proper Arabidopsis growth and care. It provides sufficient space for growing the plants to maturity under carefully controlled temperature, humidity and light conditions. The inside of the chamber provides two tiers of shelving that are vertically adjustable to allow plant growth up to 20.8” per tier. The IntellusUltra™ control system provides users with unparalleled control of the conditions inside the chamber as well as options for program linking.

Percival’s IntellusUltra Controller

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

Lighting System

  • Each tier of shelves is lighted by cool white fluorescent lamps and incandescent lamps properly spaced for uniform light intensity over entire shelf
  • Intensity programmable up to 3350 micromoles/m2/sec of light irradiance measured at 6” from lamps on 3 on/off light events
  • Two levels of programming of fluorescent lighting and one level of programming of incandescent lighting
  • Programming and control of the lighting is done via IntellusUltra real time controller


  • Conditioned air circulates through a rear wall duct and is picked up by a specially designed fixed air diffuser located at the bottom of each tier (air is then delivered vertically upward at a slow speed through each shelf)Air diffuser insulates shelf level experiments from heat generated by underlying light fixture

Cabinet Construction

  • 26-gauge smooth galvanized white side walls and top reinforced with 24-gauge backer plates
  • Interior floor constructed of 24-gauge #304-4 stainless steel
  • 24-gauge smooth white galvanized exterior
  • NSF compliant seam design
  • Overall wall thickness is 2”
  • Foamed-in-place non-CFC insulation
  • One 1 1/4” diameter access port on right hand wall
  • Chamber floor equipped with floor drain and hose assembly
  • Contains caster assembly and adjustable leveling legs to compensate for floor unevenness in the lab


  • Woodless construction using 2” thick foamed-in-place non-CFC Urethane insulation with 93% closed cell, R-value of 12.5, K-value of 0.16 and density of 2.2 lbs/cu. ft.


  • One door opening of 29.2” x 57.5” providing full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 29.7 cu.ft. with work area of 10.8 sq.ft. provided on two shelves


  • Two tiers of white epoxy coated steel wire shelving (each shelf is 27”D x 28.8”W)
  • Shelves side in and out easily on stainless steel rail assemblies (at lower elevation only)
  • When shelves are not mounted on rail assemblies, they are vertically adjustable in 1/2” increments
  • Maximum growing height is 21.8” per tier


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

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)
  • Solenoid valves have extended stem for quiet and long life operation
  • Ceiling mounted evaporator coils incorporate twin air circulation fans in aluminum housing (heat rejection to ambient with standard chamber: 4500 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)

Convenience Receptacles

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

Electrical Requirements

  • Consult Geneva Scientific for electrical requirements and amperage draw.


  • Additive Humidity Control with Sensor
  • Dehumidifier with Sensor
  • IntellusUltra Connect
  • Android-Based Touch Screen
  • CO2 Enrichment Package
  • Self-Contained Water-Cooled Condensing Unit
  • Dry Alarm Contacts
  • Dimmable Lighting
  • LED Lighting in Lieu of Fluorescent Lamps
