SBS-3510 User’s Manual
9.2 Filling the Sample
Depending on the viscosity of the sample, you can fill the measuring cell
using the filling tube or a syringe. When filling highly viscous samples, we
recommend using the syringe.
TIP:
The pump lever with lock function (supplied with the instrument) is suited
for any filling method. However, when you fill with the filling tube, the pump
lever without lock function is more convenient. This is why SBS-3510 comes
with this pump lever already mounted.
Take care that you fill without bubbles and that the measuring cell is entirely
filled.
Possible reasons for bubbles in the measuring cell are:
- gas bubbles in the sample,
- a leaky connection of the filling tube, the pump, or the screw plug /
syringe adapter.
9.2.1 Filling with the Filling Tube
1. Press down the pump lever as far as it will go (see fig. 7).
2. Sink the filling tube into the sample.
3. Slowly release the pump lever.

TIP:
If the movement of the pump lever feels stiff, start by filling deionized
water in order to reduce the friction. Then empty the filling tube and fill your
sample.
