New Air Cooled Dry Pump Range Ideal for Scientifi c Instruments


Edwards has launched the new air cooled nXLi dry vacuum pump range, ideal for applications where consistent performance, reliability and control are required. The nXLi provides a small footprint with quiet operation, making it a convenient and high performing yet compact vacuum pump.


The intelligent drive enables the system to achieve an enhanced performance plateau from single phase power supply, with consistent worldwide operation. There is a choice of control options, with either manual, simple remote or serial communications control as standard, allowing more flexible control options for the system builder. The pump mechanism is non-contacting and oil-free to provide extended operation with maximum up time, up to five years’ service life.


During the initial chamber pump down the intelligent transient overload protection allows a higher power draw for a short period of time, this enables the pump to evacuate the chamber from atmospheric pressure to operating pressure. This higher initial power boost enables the pump to overcome initial gas loads and once operating pressure is achieved, less power is required.


This new single phase pump is available in two options, nXL110i and nXL200i, both optimised for LCMS (liquid chromatography – mass spectrometry) and ICPMS (inductively coupled plasma mass spectrometry) duties, and capable of handling gas loads of up to 25 slm.


“Performance is at the core of our new nXLi dry pump”, commented Dave Goodwin, Senior Product Manager, High Vacuum, Edwards. “We are excited to launch this new range, based on the Edwards iXL range of semiconductor dry pumps, they provide peace of mind with a proven track record of performance.”

New Liquid Handling Platform Reduces Assay Development Time and Improves Robustness in High Throughput Screening


TTP Labtech Ltd has announced the global commercial launch of its dragonfly® discovery liquid handling technology. The novel liquid handling technology has been developed to provide researchers with a standard platform whereby they can easily develop complex assays and screen them in a robust and cost efficient manner.


TTP Labtech have continued to collaborate closely with leading pharmaceutical companies on the further development of dragonfly discovery. With an aim to deeply understand the needs of the scientists involved in early stage drug discovery, TTP Labtech have worked together with their collaborators to develop an instrument that helps the scientists achieve their goal of reducing drug discovery cycle times. The platform enables rapid and reliable low volume (200 nL upwards) dispensing from a positive displacement disposable pipette (with 4 mL capacity), and 96,384 & 1,536 well compatibility, to allow assays to be developed directly in high density plate format using a common liquid handling platform. The combination of innovative technology and the incorporation of specific hardware and software features requested by collaborators ensures that dragonfly discovery not only significantly reduces assay development time, but also enables more seamless transition from assay development in to the screening phase. Additionally, it permits them to routinely deploy design of experiment (DoE) as part of assay development, particularly beneficial for complex cellular assays.


Joby Jenkins, Director – Product Strategy, TTP Labtech, commented: “We are extremely excited to be launching this innovative liquid handling technology to the market. Dragonfly discovery provides high speed, non-contact dispensing from a disposable, positive displacement tip, which will effectively enable researchers to reduce assay development time as well as improve assay robustness in HTS.”

Process Ready Ultrasonic Flowmeter


Designed to IP65 standards the Process Atrato ultrasonic flowmeter from Titan Enterprises is built for use in demanding process and control environments. Durably constructed from 316 stainless steel and PEEK, and incorporating proprietary ultrasonic flowmeter technology, the Process Atrato offers reduced cost of ownership compared to existing flow measurement devices used in the process environment.


Rated for use up to 65°C and 20Bar the compact Process Atrato is available in 4 models operating over flow ranges from 2ml/min to 15litres/min, featuring an accuracy of ±1% over the whole flow range. Each Process Atrato is calibrated with a pre-set ‘K’ factor so all meters of the same flow range are fully interchangeable simplifying assembly and set-up procedures for OEM manufacturers looking to integrate the flowmeter into their process and control set-up.


Using patented technology that enables it to operate accurately over wide flow ranges, the Process Atrato signal processing system permits flow measurement across the whole Reynolds number range allowing both viscous and non-viscous products to be metered.
