一般描述
BIOshell™ Guard Columns provide physical (filtration) and chemical protection for costly analytical columns without compromising the very high performance of BIOshell columns. These BIOshell guard columns are capable of continuous use at pressures up to 9000 psi (600 bar) with only hand-tightening. Guard cartridges are easily replaced without removing the guard column holder from the flow path. The cartridge is packed with BIOshell Fused-Core particles. Order the guard column holder (66841-U) separately.
