Can ACQUITY columns be attached using nanoViper and Viper fittings? - WKB843

ENVIRONMENT

• ACQUITY columns
• Column hardware
• Column fittings
• Viper
• nanoViper

ANSWER

Yes, but read additional information.

ADDITIONAL INFORMATION

Waters representatives have successfully connected Waters UPLC columns using Viper and nanoViper hardware. 

HOWEVER, Waters Engineering tested the hardware seals and a 90-degree turn past finger-tight is needed to create a high-pressure seal to Waters hardware. Thermo directions call for a 45-degree turn with 90-degree maximum.

Be aware that if the fitting is over-torqued, this can cause the Viper ferrule to deform, and it may not be able to be used more than once.
