Incubator - I-22NL

The I-22NL incubator and environmental chamber allows you to control multiple settings at the same time, using the same equipment.  The I-22NL stacks two compartments on top of each other, with the sophisticated IntellUsUltra control panel situation in between.  The I-22NL gives you precise control over temperature, humidity and CO2 levels, with the ability to differentiate between the two environments.

The I-22NL chamber combines the space and functionality of the smaller, one-compartment units with two spacious chambers within one unit. Stacked for space savings and easy operation, you can control the environment within each unit separately from two different control panels. This allows you to easily compare subjects within each compartment and monitor the environment around each.  Built for continuous operation and equipped with alerts to ensure the stability of the environment, the I-22NL gives you extra space with unparalleled reliability and usability.

  • This chamber is frequently used for C. elegans, nematodes, yeast/fungi, insects, bacteria and BOD
  • 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 the philosophy to the next level with our improved IntellusUltra Controller. Now choose from the levels of functionality that meet your needs.

Lighting System

  • No lights are contained inside the chamber (Please see other models, I-22LL, I-22VL or I-22LLVL if lighting is desired)

Cabinet Construction

  • Interior constructed of 22-gauge electro-zinc plated steel
  • Exterior constructed of 18-gauge 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”


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


  • Each door opening is 29.2” x 27.5” provides full access to chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 14.6 cu.ft. with work area of 16.2 sq.ft. provided on three tiers


  • Three tiers of white epoxy coated steel wire shelving (each shelf is 28.25” x 27”)
  • Shelves are supported by shelf clips allowing 1/2” vertical adjustments
  • Maximum clearance between shelves is 11” per tier with all three 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

Temperature Range

  • 2-44C (+/- 0.5C)

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)

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
  • Please contact us for more optional items
