time, space and cost. Its compact design and size compatibility with previous models simplifies upgrades from existing pumps.”
The STP-iXA3306 offers industry-leading pumping performance. It has a maximum pumping speed of 3200 liters per second and improved throughput performance at high gas flows.
The STP-iXA2206 offers the same pumping speed of the earlier STP-A2203, yet the maximum throughput capability has been increased. It features the latest-generation small power supply, which has been incorporated into the popular onboard controller first introduced with the STP- iXA2205 pump. It also includes a temperature management system option to minimize the formation of process-generated byproducts. The pump’s five-axis magnetic bearing system and new motor and drive system ensure long life and low operating costs with maintenance intervals as long as five years.
Edwards is a leading global supplier of integrated solutions for the manufacture of semiconductors, flat panel displays, LEDs and solar cells and a leader in vacuum technology for industrial, scientific, process and R&D applications.
The company employs approximately 3,000 people worldwide in the design, manufacture and support of high technology vacuum and exhaust management equipment. Edwards invented the concept of the low-maintenance, cost-effective, commercial oil-free ‘dry’ vacuum pump and offers a wide range of other pumping technologies, and related products, supported by an international sales and service organization.
Bronkhorst Introduces CORI- FILL for Small Mass Flow Rates
Bronkhorst Cori-Tech B.V., from the Netherlands, has introduced CORI-FILL, a compact solution for fluid dosage, based around the extremely accurate mass measurement of its (mini) CORI-FLOW series of Coriolis-type instruments, for flow rates between 400 mg/h and 600 kg/h.

CORI-FILL offers all this functionality, with plug and play simplicity that enables an immediate start to dosage duties after connecting power and fluid accessories, in one compact footprint and from one supplier, with single point responsibility.
In contrast with gravimetric processes using weighing scales, where compounds are dosed one by one, CORI-FILL systems can add all ingredients simultaneously, shortening batch and agitation cycles, as well as improving quality. The amount to be dosed can be easily preset by programming the batch counters via a fieldbus connection, with all the standard digital protocols available.
Due to the small footprint of the (mini) CORI- FLOW instruments, it is possible to fit the flow meter extremely close to the shut-off valve, which results in fast response times and even greater accuracy, since there is a minimal delay effect in the pipeline. It is also possible to mount multiple CORI-FILL assemblies together in highly compact, simultaneous dosing systems, with the absence of moving parts or line intrusions which results in less maintenance and cleaning downtime.
Developed using innovative hardware and software, CORI-FILL technology features integrated batch counters and the facility to directly control a close- coupled shut-off valve for brief batch sequences down to <0.3secs, a proportional valve for longer sequences, or a liquid pump for dosing without the need for pressurized vessels.
