The following procedure explains how to replace the microwash for pipetting:
1.
Remove the tubing from the container. Have a paper towel available to prevent spillage of liquids by
wiping down the tubing as it is pulled out of the container. It is advised to remove the tubing one by one.
2.
A plastic bag, tube or vial can be used to prevent liquid from flowing out of the tubing while
exchanging the container.
3.
Remove the cap from the container and replace the used container for a new one. Contact Hygiena for
information regarding the reuse of remaining chemicals.
4.
When the container is replaced, the cap with the holes can be screwed onto the new container.
5.
Place the container back into the original position.
6.
Feed the tubing into the hole of the cap, one by one, and make sure the tubing reaches the bottom of
the container.

Priming may be necessary when air has entered the tubing. It is advised to always prime the
Autosampler III when replacing the chemicals (Chapter 6.5)
