Incubator - I-30NL

The I-30NL incubator and environmental chamber by Percival Scientific allows you to control the inside environment with meticulous detail.  I-30NL chambers accommodate a range of applications, functions and materials, with devices that are easy to read and control.  Scientists utilize the I-30NL for a variety of applications, such as bioassays, bacterial cultures, product stability testing and more.

The Intellus Ultra controller allows you to carefully monitor or manipulate the environment inside, include the temperature, humidity and CO2 levels.  The interior and exterior is constructed from electro-zinc plated steel to protect the contents inside.  With three tiers of shelving, you can work with multiple projects and specimens at once, while keeping each group organized and separated.  The I-30NL is designed to work quietly and effectively in the background, with an air circulating fan and refrigerating cycle that is easy to work around.

Add the I-30NL environmental chamber to your equipment. Contact Geneva Scientific for more information on this product.

Lighting System

  • No lights are contained inside the chamber (Please see other models, I-30BLL, I-30VL or E-30B if lighting is desired)

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 other0
  • 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 26.8” x 29.6” provides 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 three tiers


  • Three 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 8.5” 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 buildup 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: 3000 BTU/hr)

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)

Convenience Receptacles

  • One 115/1/60 convenience receptacle 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
