AZURA® V 4.1 two position valves are an excellent choice for sample injection, column selection, high-throughput sample loading or
column backflushing from analytical to preparative range.
Multiposition Valves
AZURA® V 4.1 multiposition valves make HPLC life easier through automatization of steps like column, eluent and sample selection as well as fractionation.
Special Position Valves
AZURA® V 4.1 special position valves come into play whenever a standard two- or multiposition valve reaches its limits with regard to switching options.
Injection Valves
AZURA® V 4.1 injection valves are technically 2-position or special position valves. KNAUER offers a great variety for analytical up to preparative HPLC and FPLC.
Valve Drive
The valve drive AZURA® Valve Unifier VU 4.1 enables automatic valve switching. Valves are identified via RFID technology, which guarantees an easy valve exchange of all KNAUER V 4.1 valves.
