accessories are available:
8.1 Flexible discharge tube with recirculation valve
For serial dispensing the flexible discharge tube can be used for the
bottle-top dispenser VITLAB
page 51). The specified accuracy and coefficient of variation of
the instrument are only obtained for volumes > 2 ml and by gently
approaching the upper and lower stops.
The coil of the tubing can be stretched to a length of the 800 mm
max. The entire coil must lie in regular loops and must not be twisted.
The applicable operating exclusions are those for the corresponding

Warning!
There should be no visible damage to the discharge tube (e.g.
kinks or the like). Each time you are going to use the tubing,
examine it carefully! To dispense aggressive liquids, you should
take safety measures in addition to the normal precautions. We
recommend use of a protective shield. The bottle must be sup-
ported using a bottle stand. To help avoid reagent splashing from
the tube, always grip the tube firmly by the handle and replace
into the holder after use. For cleaning rinse the tube carefully. Do
not dismantle!
