The New Brunswick Innova 4230 Refrigerated Incubator Shaker
is the perfect refrigerated incubator shaker for almost all lab situations. With
a heavy gauge stainless steel frame, both refrigeration and heating
capabilities, and a powerful internal shaking platform, this Refrigerated
incubator is fully capable of handling just about any sample parameters.
The internal Cabinet of the 4230 is composed of sturdy heavy
gauge stainless steel and has a double paned glass window on the outside to
allow internal sample viewing. The cabinet contains two adjustable stainless
steel shelves and a fluorescent light for improved visibility. The 4230 also includes an internal AC
receptacle for the sole purpose of the powering of internal devices.
The built in shaker features an audible and visible alarm,
control, display, timer and other onboard installations. The internal shaker
drive is a triple eccentric counter balanced drive with 9 sealed for life ball
bearings and has a motion of 3/4" circular standard. The rpm range is between 25
and 400 non stacked, and 25-300 stacked. The onboard timer has a time range of
up to 99.9 hours settable in 0.1 hours.
The temperature of the 4230 ranges from 20°C below ambient
with a minimum of 4°C to maximum of 75°C for 50 Hz units or 80°C for 60 Hz
units. Temperature alarms provide indication when temperature deviates > 1.0°C
All of our equipment is fully tested to perform at factory specifications before being shipped.
