Guard Cartridge systems:

Guard cartridges for protecting your HPLC columns (for columns from 2.0 to 4.6 mm inner diameter) are available in 5, 10 and 20 mm lengths. We offer two different types of cartridge holder:

1. Direct Connecting Guard Cartridge Holder

This holder is screwed directly on the HPLC column and therefore the dead volume is very low. You can use this system in conjunction with the VDS optilab column hardware only. The direct connecting guard cartridge holder is offered in two variants, Type_1 for 10 mm (K1) and 20 mm (K2) cartridges and Type_2 for 5 mm (K05) cartridges:

Type 1 - P/N: 15020508 for cartridges with 10 and 20 mm length (K1 + K2)
Type 2 - P/N: 15020508K05 for cartridges with 5 mm length (K05)

2. Stand Alone Guard Cartridge Holder

This holder is connected to the HPLC column by using a capillary or a special adapter. You can also use the stand alone guard cartridge holder in conjunction with HPLC columns from other manufacturers. We offer the stand alone guard cartridge holder in three variants:
