The Ro-Tap E Premium unit is one of two new W.S. Tyler Sieve Shaker offerings. This machine is our most quiet design ever with the improved dampening system. The control panel allows users to self select the amplitude and interval of the sieving motions. The extra large display offers operators an excellent overview of the settings and is user-friendly. The new Ro-Tap E Premium unit is ideally suited for users who demand precision and reproducible sieve analysis.


The Ro-Tap E Premium Remote offers a separate control unit for wet sieve analysis. The design and function of the lid has been specifically developed for tests where water needs to be used to assist in the particle separation. The wide-spreading spray diffuser is integrated into the cover, offering improved handling. The cover includes an inspection glass which allows observation during the sieving process.
