Incubator - I-66VL

The I-66VL incubator provides a secure, reliable, controlled environment with a larger working space. Maintaining the same precise control as smaller units and providing the same levels of specificity, the I-66VL features 47 square feet of working space inside 63 cubic feet of interior space. The specially designed compressor system maintains a uniform environment across two columns and five tiers of shelves, ideal for tests with large sample groups. The I-66VL incubator may be used for bacteria cultures, insect rearing, bioassays, storing test organisms, and many other applications. To find out more about the I-66VL incubator and to order for your lab, contact Geneva Scientific.

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 mounted vertically on each side of shelf
  • Intensity programmable up to 120 micromoles/m2/sec of light irradiance measured at 6” from LED tiles
  • 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)


  • Two door openings 29.1” x 57.5” provide full access to the chamber interior (magnetic gasket provides a tight seal to door frame)

Interior Space

  • 62.4 cu.ft. with work area of 54 sq.ft. provided on five tiers


  • Five tiers (ten shelves) of white epoxy coated steel wire shelving (each shelf is 27”D x 25.1”W)
  • helves are supported by shelf clips allowing 1/2” vertical adjustments
  • Maximum clearance between shelves is 9.5” per tier with all 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: 5300 BTU/hr)

Temperature Range

  • 4-44C (+/- 0.5C) with lights on or 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
  • Dry Alarm Contacts
