​ ​​Triangular Spiral Packing – Where Geometry Meets Efficiency​​ When you need to push the limits of separation efficiency in laboratory or specialized industrial applications, triangular spiral packing delivers a distinct advantage. As a member of the Fenske spiral family, this packing replaces conventional circular coils with a triangular wire winding pattern. This simple geometric shift creates more defined flow paths and increased surface contact—giving you sharper separations, even when dealing with challenging mixtures like isotopes. We appreciate designs that use smart geometry to solve practical problems. The triangular shape provides more interaction points per spiral turn compared to standard springs, leading to better vapor-liquid distribution. While it does come with a slightly higher pressure drop, the gain in separation performance is often well worth the trade-off in high-value applications

​​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.

​​Dixon Ring Packing – Precision in Small-Scale Separation​​ When your separation process demands high purity and precise control on a small scale, Dixon rings (also called Theta rings) deliver unmatched efficiency. Originally developed by Dr. Dixon in 1947, these wire mesh packings remain a top choice for laboratory distillation, pilot plants, and high-value chemical purification. Their balanced design ensures excellent mass transfer with minimal pressure drop – making them ideal for sensitive separations where every theoretical plate counts. We appreciate packings that perform under precision conditions. Dixon rings work because their uniform wire mesh structure provides complete surface wetting and rapid film formation. This means faster equilibration and sharper separations, even with complex mixtures like isotopes or high-purity intermediates. ​​Clear Specifications – Easy Sizing​​ Size (D×H mm) Mesh Type Surface
