Quick Overview
With automated control, the Qdry ensures repeatable outcomes with minimal user intervention. Built-in adiabatic cooling allows for fast cool-down rates and more throughput.
Features
- Easy-to-use and flexible software allowing for quick set-up of profiles.
- Status display to indicate time remaining.
- Recipe driven, with individual user profiles for quick set-up time.
- Supplied with pre-set profiles covering different sample types allowing easy start for new samples.
- Screw top chamber for easy sample loading.
- Large viewing window ensuring observation of process flow.
- Small footprint ideal for use in fume hoods.
Critical point dryer liquid CO2 requirements
All models require a cylinder of liquid CO2 fitted with a siphon tube (normally indicated by a vertical white stripe on the cylinder). If there is any doubt regarding the presence of a siphon tube, advice should be sought from the supplier.

Applications: Plants
Rapid advances in agricultural and botanical studies require usage of reliable and repeatable preparation of plant tissue. Critical Point Drying (CPD) is a method to prepare samples for SEM examination. After tissue fixation and dehydration, samples can be stored in the intermediate liquid and dried before SEM imaging.
