Using The Funnel Dispenser; Procedure - Millipore Microfil Manual De Uso

Microfil User Guide

Using the Funnel Dispenser

The funnel dispenser is designed to allow rapid dispensing of Microfil funnels
without compromising sterility. It can be used with or without laminar flow
facilities.
NOTE: Each funnel should be dispensed only prior to immediate use.

Procedure

1. Open a sleeve of funnels at the base of the pack.
NOTE: If you are using 100 mL funnels, choose a 24-count sleeve for use with
S-Pak membrane filters or a 25-count sleeve for use with EZ-Pak
membranes. For 250 mL funnels, a 30-count sleeve can be used with
either type of membrane.
2. Stand the sleeve on a hard surface, opened side up, and slide the dispenser
magazine down between the funnels and packaging.
3. Insert and position the magazine, with the funnels and packaging, on the
dispenser while holding the funnels straight and in place through the packag-
ing with the thumb and index finger. Avoid catching packaging between the
funnel dispenser magazine and base.
4. Leave the packaging in place for use in uncontrolled environments, (i.e. other
than laminar flow).
5. To gain access to a funnel, stabilize the dispenser with the index finger and
fully slide the dispenser lever sideways with the thumb. A funnel will automati-
cally drop into position.
6. Remove the funnel and process the sample as described in the "Processing a
Sample" section.
