A simple low-cost critical point dryer with continuous flow dehydration attachment.
A simple low-cost critical point dryer with continuous flow dehydration attachment is described. By using the critical point pressure chamber for all fluid exchanges, loss of material and air-drying artefacts due to specimen handling are reduced. An operating schedule that allows the optimum path around the critical point process to be followed is proposed.
