--- title: Electroformed Sieves, low micron test sieving, special test sieves description: Electroformed sieves for use with particle sizes between 5 microns and 2,000 microns --- [![CSC Scientific Company, Inc.](https://www.cscscientific.com/hs-fs/file-1239671252-jpg/images/csc-logo-1.jpg "CSC Scientific Company, Inc.")](https://www.cscscientific.com/?hsLang=en-us) # Electroformed Sieves And Sonic Sifter Sieves # Electroformed Sieves There are some inherent problems in maintaining consistent opening sizes throughout a ![Woven Wire vs ElectroFormed side by side](https://www.cscscientific.com/hs-fs/images/Woven%20Wire%20vs%20ElectroFormed%20side%20by%20side.jpg?t=1481907764105&width=146&height=60&name=Woven%20Wire%20vs%20ElectroFormed%20side%20by%20side.jpg)woven wire mesh sieve. These problems are most apparent when tight tolerances are required in the smaller sizes. **Electroformed Sieves** are one solution to this problem. The process of electroforming the sieve mesh results in very tight tolerances of the openings. It is possible to build sieves using this process that can hold a +/- 2 micron tolerance. **Electroformed sieve mesh** is normally produced using a nickle support base. Other electroformed sieve mesh materials such as copper and gold are also available. Because of the** high comparative cost of electroformed![electroformed sieve mesh](https://www.cscscientific.com/hs-fs/images/Electroformed%20Sieves-Precision.jpg?t=1481907764105&width=132&height=103&name=Electroformed%20Sieves-Precision.jpg) sieves**, they are most often used only where very tight tolerances are required. If the sieves are calibrated with glass spheres, they can be used as **reference sieves **or as a **master calibrating sieve stack**. Opening sizes can range from 5 microns to 2,000 microns, and can be made for a 1 micron increment. Electroformed sieves are available in standard inch and metric round frames. The openings can be of various shapes - standard shapes include round, square, slotted or hexagonal. The sieves are certified and come with a histogram. ### Sieve Small Particles: Sonic Sifter Sieves![Sonic_Sifter_300.jpg](https://www.cscscientific.com/hs-fs/file-1983017996-jpg/images/Sonic_Sifter_300.jpg?width=320&name=Sonic_Sifter_300.jpg) Pair **electroformed sieves** with the **Sonic Sifter** to get separations of small particles down to 5 microns.Special plastic sieve frames are available for the **[Sonic Sifter](https://www.cscscientific.com/particle-size/sieve-shakers/sonic-sifter/?hsLang=en-us)**, used to separate small and difficult-to-separate particles.   ## See Electroformed Sieves in the Online Store [**⇒ Electroformed Sieves**](http://www.cscscientific.us/page/electroformed-sieves) [**⇒ Sonic Sifter Sieves**](http://www.cscscientific.us/page/sonic-sifter-sieves) ![Electroformed Sieves-Ultra Precision.jpg](https://www.cscscientific.com/hs-fs/hubfs/Electroformed%20Sieves-Ultra%20Precision.jpg?width=320&name=Electroformed%20Sieves-Ultra%20Precision.jpg "Electroformed Sieves-Ultra Precision.jpg") [![Review These Sieves](https://no-cache.hubspot.com/cta/default/75757/85577502-8007-4abe-86f5-0f39b32f2ea2.png)](https://cta-redirect.hubspot.com/cta/redirect/75757/85577502-8007-4abe-86f5-0f39b32f2ea2) ### How May We Help You? ### Follow Us CSC Scientific Company, Inc 2799-C Merrilee Drive Fairfax VA, 22031 800-621-4778 703-280-5142 (fax) csc@cscscientific.com [![credit cards](https://cdn2.hubspot.net/hub/75757/images//creditcard.gif)](http://www.cscscientific.us) No part of this page or any other page in this site may be copied or reproduced in any way.
