Liquid Nitrogen Para-Hydrogen Generator

This Parahydrogen Generator (Flow Cryostat) is simple to use and ideal to get you quickly started with your experiments. It has been employed in a number of previously published studies (see below). The lower coil must be submerged in liquid nitrogen for conversion to occur.

When choosing to use this option, you must select an appropriately sized Dewar, and follow the instructions in the manual for proper operation.

The Dewar must have an Bore Opening of at least 8cm to insert the Flow Cryostat. To submerge the lower coil, you require at least 10 to 13cm of depth.
