Percival Scientific Incubator - I-30L

Incubators and environmental chambers by Percival Scientific allow provide complete control over internal environments, making it easy to handle, cultivate or manipulate delicate organisms or experiments. The Percival Incubator model I-30L is designed for easy and effective use with a wide variety of applications, with a spacious and secure interior to support multiple samples.

The I-30L incubator is controlled through the IntellusUltra panel, allowing the user to control temperature, humidity, CO2 and lighting inside. The I-30L is designed for maximum space and complete reliability within a compact, self-contained chamber. The temperature control unit is designed for continuous operation, preventing ice-build up along the cooling components and staying active without excessive noise or strain on the compressor.  The exterior electro-zinc plated steel protects the items inside while maintaining a stable environment.

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

  • Fluorescent lamps horizontally mounted in pairs above each shelf
  • Intensity programmable up to 125 micromoles/m2/sec of light irradiance measured at 6” from lamps on 2 on/off light events
  • Two levels of programming of fluorescent lighting
  • Programming and control of the lighting is done via IntellusUltra real time controller

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, suitable for stacking one above the other
  • Overall wall thickness is 2”


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


  • One door opening of 26.8” x 29.6” providing full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 9.6 cu.ft. with work area of 9.1 sq.ft. provided on two tiers


  • Two tiers of white epoxy coated steel wire shelving (each shelf is 16.4”D x 26.5”W)
  • Shelves are supported by shelf clips allowing 1/2” vertical adjustments
  • Maximum clearance between shelves is 9.2” per tier with both shelves installed


  • 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 build up in coil)
  • Solenoid valves have extended stem for quiet and long life operation
  • Rear chamber wall mounted evaporator coil incorporates an air circulation fan (heat rejection to ambient with standard chamber: 3200 BTU/hr)

Temperature Range

  • 2-44C (+/- 0.5C) with lights on and 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

  • One 115/1/60 convenience receptacle provided inside chamber

Electrical Requirements

  • Consult Geneva Scientific for electrical requirements and amperage draw.
