Empty Self Pack NanoLC Columns

The empty fritted fused silica capillary tubes are made for users to self pack their own nanoLC columns, either integrated or separated ones.  The frits made at tips of pulled tubes are evacuated to improve the resultant integrated nanoLC column permeability, resistance to tip clogging, and ESI sensitivity. Sol-gel frits are made at blunt ends of empty fused silica capillary tubes for self packing separated nanoLC columns.
