The filling time for a volume of 10.0 ml with a Ø3.2 ID tube is 0.8 seconds with dispenser running in
high speed i.e. 400 in rpm and 100 in acceleration.
The same volume can be obtained with Ø4.8 ID tube in 0.55 seconds for the same parameters.
The contrast here is outweighed by the fact that Ø3.2 ID tube will in this case yields better accuracy
than the option of using Ø4.8 ID. But as it is indicated the capacity will be higher with Ø4.8 tube since
filling time is shorter.
The above mentioned example should be considered as guidance only, and adjustments should be
done for the individual applications.
4.4 Assembly of tubes and Y-connectors
Before mounting the tubes in the dispenser head
the tubes must be assembled with a Y-connector.
When the Y-connector has been assembled,
mount the tubes in the dispenser head, as shown
in 4.5
Each set of tubes and y-connector must be assembled as
this.
