Vigreux Columns Spherical / Conical Ground Joints
Vigreux columns have a lower separating efficiency than packed columns with Rasching rings but can work with small volumes of fluid and produce low pressure loses. Useful in systems with low pressures up to approximately 5 mbar. The columns are delivered with a high vacuum insulation (10-6 mbar) and silvering with viewing strips.
