No. Description
1 Knurl
2 Capillary
3 Slot
1. Insert the Viper capillary into the connection port.
2. Tighten the connection by the knurl.
TIP Note the slot in the knurl. For narrow connections, you can easily
remove the knurls from neighboring capillaries through this slot and
attach them again later.
3. Check whether the connection leaks. If leakage exists, follow the
steps further down.
1. Tighten the connection a little more.
2. If leakage continues, remove the capillary.
3. Clean the capillary ends carefully by using a lint-free tissue wetted
with isopropanol.
4. Reinstall the capillary.
5. If the connection continues to leak, install a new Viper capillary.
Connect the inlet capillary and waste line to the flow cell when the flow
cell is installed to the device.
