HypOxystation® H155 HEPA
Define your Environment

H155 HEPA Hypoxia Workstation

The Whitley H155 HEPA HypOxystation is the tallest, widest, deepest hypoxic chamber in the HypOxystation range. It has a usable internal capacity of 1,900 liters and can accommodate a variety of equipment items such as live cell imaging devices and microscopes.

The generous internal height facilitates easy pipetting and all cell manipulations can be performed without removing them from your required hypoxic conditions. The H155 HEPA is equipped with the Whitley Internal HEPA Filtration System. Levels of atmospheric cleanliness inside the workstation exceed the requirements of ISO 14644 Class 3 and we can provide proof of atmospheric cleanliness.

This workstation provides precise environmental control while leaving plenty of room to work, incubate and conduct analysis. Two rapid 16 liter airlocks prevent compromising conditions inside the chamber when you are entering and exiting. The airlocks operate independently and take only 60 seconds to run a cycle. Each airlock can accommodate 10 x 500ml Duran bottles.

If you need to aspirate biological liquid waste from inside the chamber, order with a Vacuum Take-off Port and the Whitley AsPROvac for the perfect package.
