OPTI-GUARD™ Guard Columns

No holder needed
Step filtration design
Color coded
Compatible with any 10-32 column - tube stem automatically adjusts to fit all brands of columns, assuring perfect zero-dead-volume connections
Simple hand-tight connection
No bigger than most hand-tight fittings - attaches directly to the column, fitting into most column heaters

The OPTI-GUARD was designed to eliminate the time required to verify performance and troubleshooting. Everything from the packing to the dimensions have been selected for optimal performance across multiple brands of analytical columns and diverse laboratory applications. Even when used with narrowbore analytical columns, no change in efficiency will occur.Direct connection to the analytical column and the stem containing the frits and packing ensure that added extracolumn volume is minimized. No additional fittings or tubing requirements means less potential dead volume.
