The new tip cones of Biohit Proline
pipettors (>10 µl) allow the use of a
changeable filter as an option. The filter
prevents liquids and aerosols from
entering the pipettor. Two types of
filters are available: a Safe-Cone Filter
Standard and a Safe-Cone Filter Plus
(see cat.no. in Chapter 1.1). Plus filters
block the passage of liquids com-
pletely. The filters do not affect the cali-
bration of the pipettor (Fig. 8).
1. Push the tip ejector down (1.).
2. Push the opening tool pin between
the ejector bar and ejector collar to
release the locking mechanism (2.).
3. Pull the ejector collar off (3.).
4. Install the 300 µl collar by pushing
the collar locking pin into the
ejector bar hole, keeping the tip
ejector pushed down.
5. Release the tip ejector and test
that it runs smoothly.
