Reach In Plant Growth Chambers E-41L1

The E-41L1 Seed Germination Chamber by Percival® Scientific is specially designed to optimize research and experiments with seed germination and plant development, including lighting effects on vascular plants, plant pathology, seedling germination, production, soil conditions and much more. The E-41L1 chamber gives you precise control over the interior environment while exterior insulation and 22-gauge electro-zinc plated steel keeps the environment stable. Lighting, temperature, airflow and other factors are dispersed evenly throughout the 6.8 square feet of workspace. The 77 inch tall chamber can be used for seed germination and other plant studies, with plenty of storage space and growing room.

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

  • One tier of lighted shelving, lit by SciWhite LEDs with enhanced red
  • Intensity programmable up to 800 µmoles/m2/s of light irradiance measured @ 6″ from LEDs
  • Programming and control of the lighting is done via IntellusUltra real time controller
  • Dimmable between 10-100% output


-Air circulation inside chamber is from a specifically designed air diffuser (air travels along the entire back wall, over the shelves and returns to the ceiling fans through an opening between the light fixtures and the doors)

Cabinet Construction
-Interior constructed of 22-gauge electro-zinc plated steel
-Exterior constructed of 18-gauge exterior electro-zinc plated steel
-Welded seams and joints on outer and inner shells
-Inner shell supported by non-compressing/non-thermal conducting material locking inner liner in place without a metal-to-metal bond to outer case
-Chamber is completely self-contained

-Woodless construction using CFC free insulation (overall wall thickness is 2”, ample insulation for maintenance of stated temperature range)

-One door opening of 36.75” x 57.5” providing full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space
-37.2 cu.ft. with work area of 6.8 sq.ft. provided on one tier

-One tier of white epoxy coated steel wire shelving (shelf is 36.3”D x 27”W)
-Shelf is supported by shelf clips allowing 1/2” vertical adjustments
-Maximum growth height is 48.8”

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

-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 coil incorporates twin air circulation fans in aluminum housing (heat rejection to ambient with standard chamber: 4500 BTU/hr)

Temperature Range
– 7-44C (+/- 0.5C) lights on and 2-44C (+/- 0.5C) lights off

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 120/1/60 convenience receptacles provided inside chamber

Electrical Requirements
-Consult Geneva Scientific for electrical requirements and amperage draw.
