Cleaning / Examining Needles
It is occasionally necessary to clean or examine the needles. To facilitate either of these
operations remove the Needle Head according to previously noted instructions
–
refer to
Fitting /
Changing the Needle Head.
To clean contaminated needles carry out one of the following procedures:
1.
Autoclave the Needle Head according to your company's standard protocol.
2.
Using a 2ml deep well microplate (Porvair P/N 219009), immerse the needles fully into the
plate, partially filled with a suitable strong solvent. DO NOT use strong alkali solutions since they
could damage the aluminium Manifold plate. Ensure that the cleaning solution only comes into
contact with the needles.
3.
After a suitable period of time (possibly overnight), remove the Needle Head from the solvent
and examine. If it has been cleaned satisfactorily/decontaminate it with a suitable solvent or de-
ionised water reinstall the Needle Head and operate the Ultravap for several minutes until needles
are completely dry.
Cleaning the Needle Head
This can be achieved in two ways:
1.
Remove
the needle head and autoclave to your company’s standard protocol.
2.
Using a 2.0ml deep well micro-plate, immerse the needles fully into the plate, filled with a
suitably strong solvent (Nitric acid is commonly used).
3.
After a suitable period of time, remove the needle head from the plate and operate the
Ultravap Levante for several minutes, until the needles are completely dry.
