​ ​​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 where purity is the ultimate goal. ​​Clear Specifications – Optimized for Precision​​ Size (mm) Surface Area (m²/m³) Void Ratio (%) Bulk Density (kg/m³) 1.5 3500 80 1500 3 2800 84 1200 4 2500 88 1100 ​​Performance Highlights​​ ​​Theoretical Plates:​​ Up to 45 plates per meter ​​H.E.T.P.

​​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. ​​Clear Specifications – Multiple Sizes for Precision Matching​​ Specification Details Available Diameters 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, up to 12mm Coil Height Range 25mm – 58mm (custom lengths available) Material Options Stainless steel, glass fiber, specialty alloys Profile Variants Round, triangular, square, polygonal coil shapes ​​Ideal Applications​​ High-purity distillation experiments Laboratory-scale batch separation Pilot plant testing and process development Specialty chemical and pharmaceutical refinement ​​Why Choose Fenske Spiral Packing?​​ ​​Rapid Wetting:​​ Capillary action ensures full liquid distribution almost instantly ​​High Surface Area:​​ Fine wire construction maximizes vapor-liquid contact ​​Low Hold-Up:​​ Minimal residual liquid volume reduces mixing between batches ​​Flexible Geometry:​​ Multiple shapes and sizes match your column specs If you value repeatable, high-resolution separations at lab scale, this time-tested packing remains a first-choice solution.

​​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 Area (m²/m³) Bulk Density (kg/m³) Theoretical Plates/m 2×2 100 3500 670 50–60 3×3 100 2275 520 40–50 4×4 100 1525 380 30–40 5×5 100 1180 295 20–30 6×6 80 1127 280 17–20 7×7 80 1095 265 14–17 8×8 80 987 235 11–14 9×9 80 976 200 8–11 ​​Where Dixon Rings Excel​​ Laboratory and pilot-scale distillation High-purity chemical and pharmaceutical separation Isotope separation and development Fine chemical and specialty intermediate purification ​​Why Choose Dixon Rings?​​ ​​High Efficiency:​​ More theoretical plates per meter than most random packings. ​​Rapid Response:​​ Low hysteresis accelerates process stabilization. ​​Full Wetting:​​ Mesh structure ensures complete liquid distribution. ​​Flexible Sizing:​​ Available from 2mm to 9mm for column diameters from 20mm to 300mm.

​​Metal Raschig Rings – Time-Tested Performance, Modern Reliability​​ Sometimes the simplest solutions are the most enduring. Metal Raschig rings have been a trusted name in tower packing for over a century – and they’re still chosen today for one simple reason: they work. These straightforward cylindrical tubes create an efficient, predictable environment for vapor and liquid to interact. While newer packings have emerged, Raschig rings remain the practical choice for high-capacity duties, retrofits, and budget-conscious projects. We appreciate designs that prioritize function over complexity. Raschig rings work by providing ample surface area in a durable, open structure. This promotes effective mass transfer while minimizing pressure buildup.
