Many industries rely heavily on accurate filtration in order to avoid cross-contamination or poor quality of product.
filtration
challenges
The growing requirement for finer and finer apertures with faster and faster output demands analysis and consideration of droplet /particle size, whether liquids, sugars, starches etc. It is necessary to ensure:
- precise, small holes
- different shaped holes
- no imperfections
how we help
Tecan’s chemical etching process allows aperture profiles of components to be easily and accurately optimised – not only in size but also shape – to ensure efficient throughput of the material being processed.
This industry has evolved from using nickel to stainless steel and because of the process we use, Tecan can produce tiny aperture holes in the finest of materials.
We have helped leading companies in the filtration industry by providing high-precision sieves, meshes and filters to deliver quality to a number of applications.

Yes. Tecan manufactures precision etched filters, meshes and sieves for accurate filtration, backed by over 50 years of precision-etching experience.
Tecan manufactures etched sieves, fine meshes, filters, flow discs and precise apertures used to control the size of particles and droplets across a wide range of filtration applications.
An etched filter is produced as a single flat sheet with precisely positioned apertures, so it is flat, burr-free and dimensionally stable, unlike woven mesh which is made from interlaced wires. This gives more consistent aperture size, position and open area, and therefore more repeatable filtration.
Tecan’s etched filtration components are used across medical, food and beverage, industrial, scientific and automotive applications, wherever accurate and repeatable filtration is required.
Tecan etches filters, meshes and sieves from stainless steel, nickel and nickel alloys, copper and other metals, including bio-inert materials for medical filtration. For material options, see our guide to choosing the right metal.
Tecan etches filtration apertures down to a minimum feature size of approximately 20µm, holding a typical tolerance of ±10% of material thickness above 0.15mm, and ±15µm minimum below 0.15mm, on material from 25µm to 2mm thick.
Yes. Because photochemical etching uses digital tooling, Tecan produces custom aperture shapes, sizes, spacings and open areas to your specification, and can vary the pattern across a single part.
