Packable Fractional Columns
These hemple fractional columns have 1-2 sets of vigruex on the bottom to hold any packing you choose to add. These columns are vacuum jacketed to provide insulation and minimal temperature loss to the column and surroundings. Silvering creates even greater insulation by reflecting the IR heat back inside the column and together with vacuum jacketing provides exceptional insulating capabilities. Increased insulation means a longer column with more theoretical plates can be used and can provide more separation capabilities.
Joints selected are the same size on both ends. Size is the length of the jacketed portion only.
All columns now have a dewar joint on top and are fully jacketed.
We make all our glassware so any variation of joint, sizes, or other features are available upon request.
