5.5.4.2 Connecting Viper Capillaries
UHPLC System
Operating Manual
This section describes how to connect Viper™ capillaries. All Viper flow
connections in the Vanquish system are designed to be finger-tight.
To connect Viper capillaries with knurls, follow these steps:
NOTICE
• Tighten or loosen Viper capillaries only with your fingers. Do not use
tools other than the knurl that comes with the capillary.
• To avoid damage to the capillary or connection, tighten and loosen
the Viper capillaries only when the system pressure is down to zero.

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.
TIP
Depending on the modules used in the system, you may also find other
fitting connections. Refer to the Operating Manual for the respective
module for information on how to handle these types of fittings.
