Disk Holder O-Ring Kit (P/N 071059)
NOTE If any O-ring develops a leak, Thermo Fisher Scientific
recommends replacing the O-ring on each channel. The
kit contains six O-rings.
Remove the Defective O-Ring
1. Disengage the disk holder and unscrew the locking collar.
2. Slide the sleeving tubing up to reveal the inner tubing. Be careful not to crimp
or kink any tubing.
3. Remove the tubing clamp and tubing from the top of the disk holder.
4. Unscrew the bolt that secures the disk holder top assembly to the clamp
mechanism.
5. Locate the snap ring pliers provided in the Disk Holder O-Ring Kit. Set the
pliers for use with an external snap ring (i.e., as you squeeze in on the handles,
the tips of the pliers should move away from each other).
6. Remove the snap ring holding the locking collar and large washer to the top
(white polymer) part of the disk holder (see
