Maintaining
D-Rings
Every 2 weeks, we recommend applying silicon grease (supplied with the
instrument) to the D-rings attached to the nozzles to maintain proper attachment
of the tips to the nozzles and prevent any leakage as described below.
To replace D-rings, see below.
•
Using a gloved hand, take some silicon grease on the finger.
Note:
If you have used up the grease included with the instrument, you can use any
vacuum type silicon grease.
•
Apply the silicon grease on the surface of the D-rings attached to the nozzles
as shown below. Avoid putting any grease into the nozzle. If you accidentally
put some grease into the nozzle, remove the grease using a wire.
•
Wipe off any excess grease on the nozzles edges using laboratory wipes as
excess grease interferes with the operation of the instrument.
For any other repairs and service, contact Technical Support (page 45). Do not
perform any repairs or service on the iPrep
™
Instrument to avoid any damage to
the instrument.
Replacing the
D-Rings
Once a year, we recommend replacing the D-rings attached to the nozzles to
maintain proper attachment of the tips to the nozzles and prevent any leakage
as described below.
One set of 13 D-Rings are included with the iPrep
™
Instrument. To obtain
more D-Rings, contact Technical Support (page 45).
1.
Using a small forceps or pliers, remove each D-Ring from the nozzle by
pulling out the D-Ring and then sliding out the D-Ring from the nozzle.
2.
Apply some silicon grease to the nozzle.
3.
Remove one D-Ring from the package and slide on the D-Ring on the
greased nozzle. Ensure the D-Ring is placed properly on the nozzle to
prevent any leakage.
Note:
General recommendation is to replace the D-rings after about 100-150 extractions.
