No sharp edges for easy handling and sieving by hand as part of on-site sampling. The rounded edge also helps seal the gap between multiple sieves in a stack and prevents any unwanted material from accumulating. The use of NBR gaskets on the outside of the sieves allows cleaning & drying at +80 °C without the need of removing the O-Ring.

Lower edge designed for effortless stacking: Our test sieves are easily compatible with 200 mm sieves of all major test sieve brands and can be easily used in a stack of sieves. Blau-Metall sieves and sieve accessories are also compatible with sieve shakers of all the major manufacturers.

• 3D Laser Engraving
• Long-lasting identification
• Tamper-proof through 3D structure
• Font sized for easy reading of sieve size and serial number
• Easily readable in various lighting conditions
• No rivets or gaps for easy handling & cleaning

Unique, tamper-proof serial number for every sieve allows for full traceability from the initial production through regular inspections as required by numerous national grain intervention boards.

• Stainless Steel (AISI 304) perforated plate
• High-precision apertures according to ISO 5223 / ISO 3310-2
• Long lifetime with high reliability for all sieving tasks
• Rigorous optical inspection insures compliance of every single sieve
• Custom perforations available on request

Each sieve has a dual solder joint to form a highly durable and complete seal between the internal surfaces of the sieve and provide additional reinforcement.

• Fully sealed to avoid cross contamination
• Smooth surface for easy cleaning & quick drying
• Temperature-resistant up to 160 °C
• Corrosion-resistant - no degradation with acidic or caustic cleaners

All sieve components are made from AISI 304 stainless steel to create a highly durable, long-lasting sieve that will maintain its dimensional stability over an extended lifetime of many years.

Sustainability through re-certification instead of re-purchase on an annual basis is a cornerstone of our philosophy.
