Kit of tools to push frits into 3900 type columns. Contains 1 each tool to push in bottom frit for all columns, 1 each tool to push in top frit for 40 nm scale, 1 each tool to push in top frit for 200nm scale and 1 each tool to push in top frit for 1um scale. This kit of tools is used to push frits into 3900 type columns if you are assembling your own columns. It is designed to insure consistency in placement of frit which results in consistency of flow rate from column to column.
Remember that the other variable in assembling columns that can contribute to flow rate variability is the quantity of synthesis media added to each column. Each column must get the same quantity of synthesis media. These tools do not measure quantity of synthesis media.
