6.2.1 Flexible discharge tube with recirculation valve
For serial dispensing the flexible discharge tube can be used for the bottle-top dispenser Dispensette
S and Dispensette
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
maximum length of 800 mm. Before use, the tube must lie in regular loops and must not be twisted.
The operating exclusions for the respective instrument in use apply.
Assembly
Use only undamaged tubing
There should be no visible damage to the discharge tube (e.g. kinks, etc.). 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 supported 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!
