55 Pumps, Valves & Liquid Handling New Compact Vacuum Controller for existing Vacuum Pumps
The new CVC 3000 detect is a compact two-point vacuum controller for connection to existing vacuum pumps or vacuum networks. With its integrated chemistry vacuum valve, it forms a compact, easy to install and ready to use vacuum control package.
The advanced electronic vacuum control significantly increases the efficiency of the laboratory process, such as for solvent recovery on a rotary evaporator, as well as protecting the environment. The control function ‘detect’ automatically finds the boiling pressure of a solvent, thereby minimising the need for user intervention. There is no need for a laborious manual search of the boiling point, even when working with complex solvent mixtures. Excessive foaming and the resulting loss of sample material can be prevented. The user saves time and can concentrate on more important tasks. A built in program function also enables the setting of individual pressure-time profiles, so that more complex applications can be carried out automatically and with accurate reproducibility. The CVC 3000 detect from Vacuubrand is available as a desktop version, as well as for scaffold mounting.
28569pr@reply-direct.com New Vacuum Solutions for European XFEL Developed
The European X-Ray Free-Electron Laser (European XFEL) is a research facility generating ultrashort X-ray flashes: 27,000 times per second and with a brilliance that is a billion times higher than that of the best conventional X-ray radiation sources. The flashes are produced in underground tunnels and will allow scientists to map atomic details of viruses, film chemical reactions, and study the processes in the interior of planets.
The processes at European XFEL require ultra-high (UHV) or high vacuum (HV) conditions. It is important to maintain a good level of vacuum so that the XFEL beam and high power lasers can propagate and interact with matter at the experiment stations without being affected by air molecules or hydrocarbons generating background signals on the detectors. Pfeiffer Vacuum, in cooperation with European XFEL, has developed solutions ranging from vacuum pumps to leak detectors to vacuum components for many vacuum applications at European XFEL. All solutions were exclusively tailored to the specific needs and demands of these applications.
“High vacuum applications at XFEL predominantly use Pfeiffer Vacuum turbopumps, controllers and gauges. Additionally, our portable pump carts are equipped with Pfeiffer
Vacuum solutions”, said Ian Thorpe, instrument engineer for HED (High Energy Density) Instrument at XFEL. “It was important that the vacuum equipment could be integrated into the specific XFEL control system.”
The idea to build the European XFEL was born at DESY (Deutsches Elektronen-Synchrotron), one of the world’s leading centres for the investigation of the structure of matter and a long-term partner of Pfeiffer Vacuum. Being the main shareholder of European XFEL, DESY collaborates on the construction, commissioning and operation of the 3.4-kilometre-long facility. Together with international partners, DESY constructed the heart of the X-ray laser: the 1.7-kilometre-long superconducting accelerator including the electron source. It starts at the DESY site in Hamburg and stretches to the town of Schenefeld in the German federal state of Schleswig-Holstein.

Single-Use Liquid Flow Sensor for the Measurement of the Lowest Flow Rates in Biomedical Applications
Sensirion presents its single-use liquid flow sensor LD20 aimed at the fast, precise and reliable measurement of the lowest flow rates. The flow sensor series is based on a successful design study that was first presented in 2014 and has already received several international awards. Product development of the LD20-2600B, the first representative of the new single-use sensor series, is now complete and it is ready for high- volume production. The intelligent, compact and cost-effective sensor is suitable for a wide range of biomedical applications in the field of critical and home care, such as monitoring of ambulatory infusion pumps, ultra- low flow measurements of precious medications in neonatology and paediatrics, continuous urine flow measurement, to name but a few.
The LD20-2600B liquid flow sensor is based on Sensirion’s proven CMOSens® Technology and optimises costs by simplifying the design without sacrificing easy fluidic, electrical and mechanical connections. Barbed fittings ensure safe and secure integration in the fluidic line. The straight and unobstructed flow channel design has no moving parts. Medical-grade wetted materials provide outstanding chemical resistance and excellent media compatibility. While providing bidirectional measurement of flow rates from 1000 ml/h down to single digit ml/h, the sensor also reliably detects common failure modes such as occlusion, air in line or infiltration with unprecedented speed and sensitivity.
Smaller LD20 product versions (e.g. the LD20-0600x) for even lower flow rates down to only a few hundred µl/h will be released in the future and are now available in sample quantities.
Sensirion’s liquid flow meters are already being used in numerous challenging applications, from diagnostic instruments to process control in the semiconductor industry. Combined with Sensirion’s extensive experience in the medical field, the new single-use LD20 series will enhance your applications with maximum safety, performance and reliability.
