Description
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.Features
- 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
