Click here to see the used and refurbished New Brunswick I26 incubator shaker from American Instrument Exchange.
New Brunswick has been making quality incubator shakers for years, dating back to the old Innova 4900 model, with a single chamber and three to four independently controlled shaking platforms. The 4900 was supplanted by the stacking Innova 4430 and 44/44R units which offered not only independent controls for each shaking platform but also separate chambers for multiple temperature parameters to be run simultaneously.
And new there’s the New Brunswick I26, with a tight temperature uniformity of less than 1°C throughout the chamber and shaking control accuracy of +/- 1 rpm. The speed range for a single unit is 25 rpm to 400 rpm. (Stacked unit must be kept at 250 rpm or less in order to avoid unstable conditions that could cause the stack to tip or fall, which, trust us, is not fun to see happen.)
There are two design features we’d like to note regarding the I26 because they contribute to a long-life span and reduction in required and anticipated maintenance: the heaters and the triple eccentric drive.
We’ll start with the drive. For years New Brunswick has been designing their shakers with cast iron, triple-eccentric counterbalanced drives. The simplicity of the design belies its brilliance. This vibration free construction not only provides uniform stroke and operation but also is durable almost to the point of being unbreakable. So not only do you get reproducible performance time and time again but you also have a platform that can easily handle heavy loads with not strain or damage to the machine.
Likewise, the heaters are designed with longevity and low-maintenance in mind. These low-watt density heaters are resistance type and have high temperature thermostats. To heat the chamber, the microprocessor controller outputs a Pulse Width Modulation (PWM) signal to control the power level of the 650W heater. This cycle time is fast enough to prevent noticeable changes in air temperature due to the cycling, and slow enough achieve a 1 part in 250 output resolution when the power switching is done by a zero-voltage switching SSR. What does all that mean in plain English? It means that the heater doesn’t have to work too hard to heat the chamber, so its anticipated life span is longer than in comparable chambers.
All in all we’ve been very impressed with the operation and performance of New Brunswick I26 thus far. So if you’re looking for an incubator shaker, please email or call us today for information on the New Brunwick I26. Thanks!
