Incubator - I-41LLVL

Percival Scientific has built a strong reputation on scientific products that are reliable, versatile, long-lasting, and easy to use. The I-41LLVL incubator provides standard features useful in nearly any lab working with controlled environments, with exceptional construction that ensures years of successful use. The IntellusUltra Controller provides pin-point controls and additional features that allow you to maintain a stable environment with nearly any parameters. Using an insulated electro-zinc plated steel interior and exterior, the I-41LLVL holds the interior environment while the controller monitors temperature levels, humidity, CO2, and light.

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

  • Linear LEDs vertically mounted and linear LEDs horizontally mounted in pairs above each shelf
  • Intensity programmable up to 200 micromoles/m2/sec of light irradiance measured at 6” from LED tiles
  • Two levels of programming fluorescent lighting, one for theone for the horizontal LEDs and the other for the vertical LEDs
  • Programming and control of the lighting is done via IntellusUltra controller
  • Dimmable between 5-100% output.

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
  • Overall wall thickness is 2”
  • One 1 1/4” diameter access port on R.H. 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 CFC free insulation (overall wall thickness is 2”, ample insulation for maintenance of stated temperature range)


  • One door opening 36.8” x 57.5” provides full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 37.2 cu.ft. with work area of 27.2 sq.ft. provided on four tiers


  • Four tiers of white epoxy coated steel wire shelving (each shelf is 27”D x 32.6”W)
  • Shelves are supported by shelf clips allowing 1/2” vertical adjustments
  • Maximum clearance between shelves is 10” per tier with all four 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 buildup in coil)
  • Top mounted refrigeration system allows easy access for maintenance (e.g. cleaning)
  • As heat is rejected, it rises and is dissipated into room without having any effect on inside temperature of cabinet
  • 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: 3800 BTU/hr)

Temperature Range

  • 5-44C (+/- 0.5C) with lights on and 2-44C (+/- 0.5C) with 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 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
