Response Due Date: February 10, 2020
Vendor Name:
Geneva Scientific, LLC
Product or Service: Tissue Culture Chamber: Model CU-22L
Geneva Scientific Class II Type A2 Biological Safety Cabinet R-Series:
Geneva Scientific Class II Type A2 Biological Safety Cabinet:
This Percival Scientific chamber was specifically designed for plant cell
culture. Its unique design of air diffuser with slow vertical airflow, fixed
lamp bank and slide-out shelves helps to eliminate condensation on Petri
Dish Lids.

Airflow: The conditioned air circulate through a rear wall duct and is
picked up by a specially designed fixed air diffuser located at
the bottom of each tier. The air is then delivered vertically
upward at a slow speed through each shelf. The air diffuser
insulates shelf level experiments from the heat generated by
the underlying light fixture. This design minimizes
condensation on dish lids.
Light Intensity: 140 micromoles/m²/s
Lighting System: Each tier of shelves per compartment is lighted by
cool white fluorescent lamps properly spaced for
uniform light intensity over entire shelf. Intensity
programmable up to 140 micromoles/m²/s of light
irradiance measured @ 6” from the lamps on 2
on/off light events. Programming and control of the
lighting is done via IntellusUltra controller.
Airflow/Circulation: Conditioned air circulates through a rear wall
duct and is picked up by a specialty designed
fixed air duffuser 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)
Cabinet Construction: Interior constructed on 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 ¼” diameter access
port on R.H. wall (one per compartment).
Chamber floor equipped with floor drain and
hose assembly. Contains caster assembly and
adjustable leveling legs to compensate for floor
unevenness in the lab.
Insulation: Woodless construction using CFC free insulation (overall
wall thickness is 2”, ample insulation for maintenance of
stated temperature range)

Doors: each door opening 29.2” x 27.8” providing full access to
chamber interior (magnetic gasket provides a tight seal to door
Interior Space: Total 29.1 cu. ft. with work area of 21.6sq. ft.
provided on two shelves per compartment.
Shelving: Two tiers per compartment of white epoxy coated steel
wire shelving (each shelf is 27”D x 28.8W). Shelves side in
and out easily on stainless steel rail assemblies. Maximum
growing height is 6”.
Finish: Interior and exterior painted with high reflective,
environmentally friendly, high temperature baked white
powder coating.
Refrigeration: Twin condensing unit (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. Ceiling mounted
evaporator coils incorporate dual air circulation fans in
aluminum housing (heat rejection to ambient in
standard chamber = 5000 BTU/hr).
Convenience Receptacles: One 115/1/60 convenience receptacle
provided inside each compartment.
Controller: NEW IntellusUltra
Single control system providing 24 hour chamber
monitoring and control of all programmed variables
such as temperature.
Also controls lighting, humidity & CO2 when these
options are purchased.
Step and Ramp mode
500 total programs steps over 50 total programs
16 total programmable light/event outputs
Deviation alarms & light lifetime alarms
4 Program Modes: Manual, Diurnal, Program, &
Non Circadian
3 daytime and 3 nighttime temperature offsets
On-board diagnostics, ambient temperature
monitoring, and power failure event logging
Alarm Display/Audible Buzzer
Dual experiment protection with primary limit and
independent secondary limit
