Stainless Steel Test Sieves

stainless steel sieves

Newark Wire Cloth’s precision Test Sieves provide consistent, repeatable, and reliable results for particle sizing from 5” (125 mm) down to 0.0008” (20 microns).  Sieves are manufactured in accordance with
ASTM E11 and ISO 3310-1.  All Stainless Steel construction.  Sieve frames are die stamped, stackable, crevice free, and laser marked; providing for accurate identification of the sieve and easy stacking of multiple sieves when performing a sieve analysis.

Newark fabricates Test Sieves conforming to:

Types of Construction

Pure Tin Soldered

Pure Tin Soldered Test Sieve

Pure Tin Soldered Test Sieve – shown. Looking into the sieve.Inset – shown looking at the underside of the sieve

Pure Tin Soldered Test Sieves are assembled using Pure Tin Solder to secure the sieve cloth to the test sieve frame.

Most Pharmaceutical, Food, and Beverage applications permit the use of Test Sieves fabricated with Pure Tin Solder.

Evidence of the Pure Tin Solder is virtually absent from the interior surfaces of the test sieve; the sieve cloth is secured to the underside of the sieve frame.

Pure Tin Soldered Test Sieves can be used for most ‘wet sieving’ and ‘dry sieving’ applications.

Pure Tin Soldered Test Sieves should not be used when temperatures are greater than 350oF.

Stainless Steel Frame / Stainless Steel Cloth Test Sieves fabricated using Pure Tin Soldered Test Sieves are FDA compliant.

NOTE: Pure Tin Soldered Test Sieves are not recommended for exposure to a caustic cleaning solution or acid as the Pure Tin Solder will break down over time. We recommend using welded Test Sieve when these conditions exist.

UV Adhesive

UV Adhesive Test Sieve

UV Adhesive Test Sieves are assembled using a proprietary state-of-the-art polymeric adhesive to secure the sieve cloth to the test sieve frame. It effectively seals the joint between the sieve cloth and the test sieve frame.

Similar to the Pure Tin Soldered construction, the UV Adhesive is virtually absent from the interior surfaces of the test sieve; the sieve cloth is secured to the underside of the sieve frame.

This adhesive has been laboratory tested and certified to be in compliance with UPS Biological Reactivity Tests in Vivo USP Plastics Class VI.

A UV Adhesive Test Sieve is autoclaveable!

NOTE: UV Adhesive Test Sieves are not the best choice if you’re looking for laboratory test sieves to use for ‘wet sieving’ or for applications with significant humidity or moisture; as the adhesive bond between the sieve cloth and the test sieve frame can break down and become weak over time.

A UV Adhesive Test Sieve is a perfect choice for most dry sieving applications.

Welded Construction

Test Sieve welded

A Welded Test Sieve has the sieve cloth continuously resistance spot to the sieve frame. The individual spot welds are overlapped, no voids thus ensuring that all product goes through the sieve screen, not around it. The Sieve Cloth is welded directly to the sieve frame; no filler metal is used. Whether a coarse mesh sieve or a fine mesh sieve all can be supplied in a welded construction.

Welded Test Sieves can be used for most ‘wet sieving’ and ‘dry sieving’ applications. They are ideal for critical pharmaceutical applications.

‘Both coarse mesh and fine mesh sieves can be supplied in a welded construction’.
