Heated Humidified Incubator/Oven - HH034

The HH series incubators/ovens utilize heat to maintain temperature from as low as 5ºC above ambient conditions to 70ºC. If your set point is within this range, you should look at the models below for maximum efficiency and cost. The HH series chambers control well within the specifications required by the FDA and ICH for GMP studies. HH Series chambers can be used as pharmaceutical stress test chambers at 50C/75%RH. Examining degradation products under stress conditions is useful in establishing degradation pathways and developing and validating suitable analytical procedures. Running the models below will save you up to 80% in electricity costs vs. a compressor unit from competitors. Additionally, parts are easily replaced since there is no compressor – should you need repairs past the warranty period. * HT (heat only) series is also available, please inquire for more information.
