​Stainless Steel Spring Packing – Lab-Scale Efficiency, Unmatched Precision​
When every fraction of a percent purity matters in your laboratory distillation, stainless steel spring packing—also known as Fenske spiral packing—delivers the control you need. Originally developed by M.R. Fenske in 1936, this elegantly simple design uses tightly wound metal coils to create exceptional surface area and capillary action. The result? Extremely thin, evenly distributed liquid films that boost separation efficiency in small-diameter columns.
We appreciate designs that solve big problems with simple geometry. These spiral packings work by turning the whole surface into a microscale wetting engine. Liquid spreads rapidly across the fine wire structure, while vapor flows freely between coils. This makes them ideal for experimental setups, pilot studies, and high-value chemical purification where consistency and reproducibility are non-negotiable.
