ScoringWafer with Handle
• Ceramic wafer is serrated on one side and straight-edged on the other to cut both fused silica and
metal tubing cleanly.
• Unique, ergonomic handle is made of soft, comfortable rubber.
Hold tubing firmly in one
hand, allowing about two
inches to extend freely.
Hold the scoring wafer at
a 45° angle to the tubing.
Exert just enough pressure
to put a slight arc in the
tubing. Pull perpendicularly
across the tubing.
Make clean, square cuts!
The tubing should
fall off on its own,
or it should easily
break at the score
with a slight tap of
the wafer.
Check the cut
against the white
of the scoring
wafer. Look for a
clean, square cut.

a clean, square
end.
Exert just enough

tubing. The tubing
should fall off or
break with a slight
tap of the wafer.

Make a clean, square cut
for optimum connector
performance. The cut on
the right will produce a
poor seal.
A Clean Square Cut...
The key to obtaining a leak-tight seal in a Press-Tight
®
connector—or in other connecting devices that
make a compression seal with the end of the column—is a clean, right angle cut at the end of the column.
If you use an unsuitable device to cut your columns, you run the risk of angled cuts or chipped or jagged
edges that will not seal effectively, or even crushing the end of the column. We offer a selection of scoring
tools that will help you properly cut your columns.
