Boost technology (nEXT240/300/400) For our Analytica Instrument Customers the "T" variants of nEXT 240,300,400 employ a unique viscous pumping stage which can be used to 'boost' the performance of the backing pump. This offers a much simplified vacuum solution with greatly improved pumping speeds and system power reduction. The example in the image below shows how the boost ports can be used to replace a primary pump on a differentially pumped system. Customers in general laboratory and R&D applications will also benefit from the improved compression achieved with the "T" variant. To take maximum...

VACUUM PRODUCTS TransCalc HSM enables the rapid modelling of vacuum systems in order to decide on variables such as inter-chamber aperture sizes and pump combinations without the need of an extended trial and error process. A typical example of how TransCalc HSM would be used to optimise your system follows three simple steps: STEP 1: Define the system with unknowns You provide us with your vacuum system requirements. CUSTOM TURBOMOLECULAR PUMPS STEP 2: A TransCalc HSM model is built An Edwards vacuum expert will produce models of solutions that match your requirements. A variety of alternative...

Our T-Station 85 is a low cost, compact turbomolecular pumping station that seamlessly combines an nEXT85H turbomolecular pump with either a dry diaphragm or oil sealed backing pump, and a simple controller, providing pumping speeds of 47 to 84 ls-1. The T-Station 85 comes with an integrated Turbo and Active Gauge controller which enables single button start/stop of the system. With the ability to control one of our active gauges, vent valve control and delayed start of the turbomolecular pump to either time or pressure if a gauge is fitted, the T-Station 85 ideal for general laboratory needs....
