Gently squeeze the sample bulb attached to the line.
To express any excess sample back into the collection bag, perform the

To use the residual air in the sample bulb to clear the fluid
from the line between the collection bag and the sample
bulb, perform the following steps:
8.21.6.4 Hold the sample bulb upright and below the collection bag.
8.21. 6. 5 Gently squeeze the sample bulb. The residual air in the bulb
pushes the product from the line into the collection bag.
8.21. 6. 6 While maintaining pressure on the sample bulb, close
clamped line between the manifold and the sample bulb.
8.21.7 Before removing the sample bulb containing the product sample,
permanently seal the line between the clamp below the manifold and the
sample bulb.
8.21. 7. 1 Disconnect the sample bulb at the seal on the line.
