Ro-Tap® RX-94 Duo Model

The RX-94 Test Sieve Shaker utilizes the same traditional design as the RX-29 model. In addition, the unit features a cavity that allows for two “stacks” of 8 in. or 200 mm diameter test sieves. This allows for twice the processing capacity in nominally the same time required to complete one test.

The RX-94 model is designed for use with 8 in. or 200 mm diameter test sieves only and feature a newly designed easy lock clamping system. Each unit is test run and serialized prior to shipment and features a 99-minute digital timer with a tolerance of .1 seconds.
