Title:
SWITCHOVER VALVE FOR LIQUID CHROMATOGRAPHY, ESPECIALLY SWITCHOVER VALVE FOR HIGH SPEED LIQUID CHROMATOGRAPHY
Document Type and Number:
Japanese Patent JP2014038095
Kind Code:
A
Abstract:
To provide a switchover valve for liquid chromatography.
The switchover valve comprises: a stator 29 which is disposed in an enclosure 3 and has a plurality of terminal ports 31; and a rotator 23 which is disposed in the enclosure 3, is rotatable and collaborates with the stator 29 in a prescribed switchover position defined by an allocated angular position, so as to fluid connect with or isolate a prescribed terminal port 31.
