Mini-Extruder Assembly Instructions
Before assembling the extruder for the first time, thoroughly clean all parts (except for the Polycarbonate Membranes and the Filter Supports) with a mild detergent solution, followed by rinsing with hot tap water and deionized or distilled water. Allow all parts to dry before assembling apparatus.
How To Assemble The Mini Extruder
Refer to the diagram to identify the parts in these instructions.

1. Place the 2 Internal Membrane Supports on a flat surface with the O-rings facing up.

2. Pre-wet 2 Filter Supports with DI water, or buffer, and place over orifice. The Filter Supports should adhere to the teflon orifice inside the O-ring inner diameter.

3. Insert the Internal Membrane Support, with the Filter Support, into the Extruder Outer Casing with the O-ring facing up.
4. Place 1 Polycarbonate Membrane in the Extruder Outer Casing over the Filter Support and O-ring. The Polycarbonate Membrane is the thin, shiny disk – do not install one of the blue paper disks which separate the Polycarbonate Membranes.

5. Pre-wet a second pair of Filter Supports with DI water, or buffer, and place over orifice of remaining Internal Membrane Support.
6. Carefully place the second Internal Membrane Support into the casing (O-ring facing down) being careful not to twist the Membrane Support when it comes in contact with the Membrane.

7. If you have the original Mini-Extruder design, place the flat washers on either side of the bearing washer and insert into the Retainer Nut. For the all-teflon Mini-Extruder, place the teflon bearing into the Retainer Nut.

8. Place the Retainer Nut on the threaded end of the Extruder Outer Casing and tighten. Tighten the Retainer Nut by hand just until it is finger tight; do not use a wrench.
