The Newark Wire Cloth Company, a leading manufacturer of Test Sieves, offers ‘superior’ quality Test Sieves; featuring our exclusive ‘Cleaner-by-Design’ construction, trademarked as our SuperlaSieve technology. Newark’s SuperlaSieve technology was designed and developed in response to customer demand for better quality test sieves; cleaner, crevice free test sieves, rugged durable construction, yet always accurate!
Today, all Newark Wire Cloth manufactured stainless steel test sieves fall under the SuperlaSieve umbrella; whether UV Adhesive, Pure Tin Soldered, or Welded.
Materials of Construction
Stainless Steel Frame Stainless Steel Cloth
Pure Tin Soldered Test Sieves are assembled using a tin solder to secure the wire mesh to the test sieve frame. Many food, beverage, and pharmaceutical manufacturing applications permit Test Sieves fabricated with pure tin solder. It is virtually absent from the interior surface of the test sieve; the wire mesh is secured to the test sieve on the underside of the frame. Pure Tin Soldered Test Sieves can be used for most “wet sieving” or dry sieving applications.
Pure Tin Soldered Test sieves should not be used with temperatures greater than 350˚F.
UV Adhesive Test Sieves are assembled using a proprietary state-of-the-art polymeric adhesive to secure the wire mesh to the test sieve frame. It effectively seals the joint between the sieve cloth and the test sieve frame.
The adhesive is virtually absent from the interior surface of the test sieve; the wire mesh is secured to the test sieve on the underside of the frame. The adhesive has been laboratory tested and certified to be in compliance with USP Biological Reactivity Tests In Vivo USP Plastics Class VI.
The UV Adhesive Test Sieve is autoclavable!
UV Adhesive Test Sieves are not recommended for “wet sieving” or for applications with significant humidity or moisture as the adhesive bond between the wire mesh and the test sieve frame can break down and become weak.
A UV Adhesive Test Sieve is a perfect choice for most dry sieving applications.
Test Sieves with a Brass Frame / Stainless Steel Cloth or a Brass Frame / Brass Cloth are assembled using pure tin solder and a food grade epoxy adhesive to seal the joint between the wire mesh and the frame. The epoxy bead prevents particle entrapment at the joint between the wire mesh and the frame.
