CU-22L Tissue Culture Chamber

Percival’s intellus ultra controller
• Controls temperature, lighting, humidity (optional)
and CO2 (optional)
• Single-board electronic solid-state design includes
10 key membrane keypad with LED indicators and
vacuum fluorescent display
• Programs can be configured to run in real time
or elapsed time
• Ramping and non-ramping program methods available
for each programming mode
• Multiple programs can be linked creating complex
environmental profiles
• Optional Intellus Web Server allows monitoring
and controlling of chamber via web browser
(requires Internet Explorer 6.0+) (this option allows
for remote monitoring and programming of chamber
including alerts and current condition updates for
up to five e-mail addresses)

Lighting system
• Each tier of shelves per compartment lighted by
(4) F17T8, 17W cool white fluorescent lamps properly
spaced for uniform light intensity over entire shelf
• Intensity programmable up to 150 μmoles/m2/s of light
irradiance measured @ 6" from lamps on 2 on/off
light events
• Programming and control of the lighting is done
via Intellus 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
• Overall wall thickness is 2" (5.1 cm)
• One 1¼" diameter access port per compartment
• Chamber floor equipped with floor drain and
hose assembly
• Contains caster assembly and adjustable leveling legs
to compensate for floor uneveness in the lab

Airflow/circulation
• Conditioned air circulates through a rear wall duct and is picked up by a specially designed fixed air diffuser located at the bottom of each tier (air is then delivered vertically upward at a slow speed through each shelf)
• Air diffuser insulates shelf level experiments from heat generated by underlying light fixture (this design minimizes condensation on dish lids)

Insulation
• Woodless construction using CFC free insulation
(overall wall thickness is 2" [5.1 cm], ample insulation
for maintenance of stated temperature range)

Doors
• Each door opening 29.2" x 27.5" (74 cm x 70 cm)
provides full access to the chamber interior
(magnetic gasket provides a tight seal to door frame)

Interior space
• 29.1 ft3 (0.8 m3) with work area of 21.6 ft2 (2 m2)
provided on four shelves
