For some uncomplicated media it is possible to clean the parts just by using a fluid like ethanol
and compressed air, which can simplify the cleaning process. But before you try it, you should
always contact our Technical Support.
INFORMATION
Nozzle inserts with small orifices
If a nozzle insert with orifices smaller than 100 µm (except for nozzle inserts with long dispensing
channels, namely J-/C-series, N-27 and N-28) happens to be still clogged after cleaning, please
clean it with MDT 316 - Nozzle Insert Cleaning Tool. For operating the MDT 316 please refer to
the “Quick Reference Guide MDT 316 - Nozzle Insert Cleaning Tool”.
Step 1 (nozzle insert)
Start with the nozzle insert. For the bore use a
nozzle insert cleaning wire. These come with
different sizes. They are not part of the cleaning
toolkit CTK and have to be ordered separately.
Important note!
Use the MDT 324 - Nozzle Insert Cleaning Holder
with all Vermes nozzle inserts. With it, you can
safely keep the nozzle insert in place during
cleaning and drying with compressed air.
Clean the surface of the inner channel using a
fluidic brush. Clean it thoroughly from above and
below with a cleaning rod.
Step 2 (nozzle fixation nut)
Clean the nozzle fixation nut. Use a cleaning rod to
clean the inside/outside of the nozzle fixation nut.
Pay special attention to sharp corners and edges.
Push a fluid box cleaner through the opening of
the nozzle fixation nut to remove persistent
residues.
Clean the bore of the nozzle fixation nut using a
fluidic brush.
Step 3 (fluid box body)
With the fluid box, clean all bores and threads with
a fluidic brush first.

Afterwards, use a fluid box cleaner. Check all bores
as well and then clean the rest of the fluid box
body.
Step 4 (cartridge base)
For the cartridge base, start with the fluidic brush
to clean all bores and openings of the cartridge
base.
Next clear the bore with a cleaning rod.
Finally use a fluid box cleaner to clean the wide
opening of the bore.
Important note!
If you use a cartridge base without integrated luer
lock, you need to clean the Fluid Box Connector
Luer Lock as follows. Otherwise, you can continue
with the next step.
Push a cleaning rod through the bore of the Fluid
Box Connector Luer Lock several times to remove
any residues of the medium.
Clean the center bore of the Fluid Box Connector
Luer Lock using a fluidic brush.
Clean the openings and thread of the Fluid Box
Connector Luer Lock using a fluid box cleaner. Use
it for the outside and the end of the bore.
Step 5 (tappet sealing)
For the tappet sealing, clean the bore of the tappet
sealing carefully with a fluidic brush.

Afterwards, clean the outside of the tappet sealing.
Keep using the fluidic brush, especially for the
outer edge.
Then clean the inner rim of the tappet sealing with
a cleaning rod.
Clean the outside of the tappet centering piece
first with a lint-free cloth.
Use a fluidic brush for the bore of the tappet
centering piece.
Important note!
There is no tappet centering piece, if you use a 2G
tappet rod.
Step 6 (valve body)
Clean the valve with a lint-free cloth.
Step 7 (O-ring)
Clean all O-rings with a lint-free cloth.
Tab. 30: Clean all components by hand
Dry all the components in the air or with compressed air. For nozzle inserts we recommend to
use the MDT 324 Nozzle Insert Cleaning Holder.
INFORMATION
A two finger seesaw test is necessary to check if the tappet rod runs smoothly through the tappet
centering screw. Otherwise, the parts have to be cleaned again.
In case you still have parts which are not completely clean after the fine purification, repeat the
corresponding cleaning steps for those components several times, if necessary. If that is still not
helping, contact our Technical Support.
