Withdrawal tube

CORTEX TECHNOLOGY

To transfer liquid from the dewar to the CryoPro unit the use of a withdrawal device is highly recommended. Our withdrawal devices are detachable, which means no excess evaporation from the dewar, when the withdrawal device is not in use. Not only does this provide the most economical and safe extraction of liquid from the storage tank, the withdrawal device also provides a filter to prevent ice crystals in the dewar from being transferred to the CryoPro® unit ensuring trouble-free operation. The withdrawal devices are fully adjustable and fit dewars of 10 l capacity and up.

Storing liquid nitrogen

A clean supply of liquid nitrogen is essential to trouble free operation of liquid nitrogen cryosurgical treatment units. To ensure a clean nitrogen supply, we advise to completely empty the storage tank (dewar) 3 - 4 times per year prior to refilling.

If necessary, water from ice crystals remaining inside the tank can be dried out by creating air circulation (e.g. using a vacuum cleaner for approx. 15 min.).

To prevent ice and other particles in the tank from entering the treatment unit when filling, always use a withdrawal tube equipped with a filter.

For a demonstration on how the withdrawal tube works check the video at the bottom at the page.
