New One-Stage Vacuum Pumps for Single and Parallel Lab Applications
For many years the one-stage vacuum pumps ME 2 and ME 2C have been widely used in chemical and pharmaceutical laboratories. These two diaphragm pump models are now available as new type NT-versions. With the well-proven VACUUBRAND diaphragm pump technology of the NT series the overall pump performance could be improved in regards of better ultimate vacuum as well as increased pumping speed. With the NT drive technology, featuring smooth running with minimised vibration, the new ME 2 NT and ME 2C NT are most suitable to serve as bench top instruments. The NT design characteristics in accordance with the corresponding two- to four-stage NT-pump lines are obvious.
Single or parallel applications with basic vacuum demand and medium gas load can be covered sufficiently.
Typical applications for use are vacuum generation for drying chambers, filtration and multi- aspiration manifolds, as well as gas transfer and evacuation applications. With the VACUU·LAN®
mini-network, as optional accessory, supply of parallel lab applications is an easy task. Both, the aluminium version with FPM double-layer diaphragm as well as the chemistry version with PTFE sandwich diaphragm for aggressive gases and vapours, follow the proven VACUUBRAND quality standard with outstanding lifetime of wear parts and ease of maintenance.
In contrast to out-dated water jet and aspirator pump systems, ecological oil-free pumping needs no fresh water and avoids emission of contaminated wastewater.

Software Tool Enables Easy Pipette Management Circle no. 364
Integra has announced VIALINK – a new pipette management tool that allows users to simply create and manage custom programs, maintain a service history and transfer firmware upgrade details between VIAFLO electronic pipettes and their PC.
VIALINK can be used to securely manage and productively organise all pipettes in a customer lab. Personnel can keep track of their VIAFLO pipettes using VIALINK to record user name, serial number, service history and latest software version installed.
Faster Strep Grouping Solution
Pipetting protocols can be set up as custom programs with VIALINK and then copied onto users VIAFLO pipettes. Users can create a program library that can hold an unlimited number of pipetting protocols. Up to 20 custom programs can then be stored on the pipette itself. With VIALINK, creating individual custom programs is both quick and easy.
Using VIALINK - important service information, such as date of last calibration or service, can be stored on the pipettes. This information cannot be deleted afterwards thereby guaranteeing an authentic service history.
Periodically as Integra releases new firmware upgrades to enhance its electronic pipetting products with new and improved capabilities - VIALINK enables users to rapidly implement the upgrades on their VIAFLO pipettes.
To use VIALINK - VIAFLO single and multi-channel electronic pipettes require a programming stand, which not only functions as connector to a PC but also serves as a handy charging stand. To use VIALINK with the VIAFLO 96 only a standard USB cable is required. VIALINK can be downloaded from the Integra website.

Thermo Fisher Scientific recently launched the Thermo Scientific PathoDxtra Strep Grouping Kit. This latex agglutination kit offers a faster strep grouping solution than traditional methods for all clinically significant Lancefield groups.
Designed to improve workflow efficiencies, the nitrous acid extraction instantaneously extracts the cell antigens and the test does not require rehydration or incubation.
“Previously, choosing the best strep grouping kit involved compromise” said Julie Elston, Global Product Manager, Immunodiagnostics, Thermo Fisher.
“Acid extraction kits offered speed but did not detect group D strep reliably, while enzyme kits detected all groups but required rehydration and incubation steps, adding significant time to testing procedures.
“With PathoDxtra there is no compromise, this kits gives instantaneous extraction and detects all clinically significant streps reliably, including group D. It really couldn’t be simpler.”
PathoDxtra provides laboratories with the opportunity to improve their workflow, save time and reduce costs.

New Linear Motor Nanopositioner Provides High Accuracy and Repeatability
A series of linear dual-axis stages offering nanometer-level performance in travels up to 160 x 160mm has been introduced by Aerotech. The new ANT130-XY stages allow travel in two dimensions with an exceptionally low profile of 85mm. With high resolution (1nm), repeatability (75nm) and accuracy (250nm) per axis, the stages support all applications that require nanopositioning performance with extreme in-position stability and smooth motion.
The ANT130-XY stages are designed for use in a wide range of research and development and manufacturing fields. These include data storage, semiconductor, laser micromachining, medical, sensor testing, inspection, material deposition and MEMS/nanotechnology device fabrication.
The stages use Aerotech’s proprietary advanced direct-drive technology as well as crossed-roller bearings to achieve the highest level of positioning performance. The direct-drive technology has no hysteresis or backlash, enabling accurate and repeatable motion in both the X and Y dimensions. All travel options (60mm x 60mm, 110mm x 110mm, 160mm x 160mm) come with the 85mm profile height.
The ANT130-XY design allows critical elements such as orthogonality, straightness and flatness to be optimised, resulting in a stage with exceptional geometrical tolerances. Its integrated cable management system is designed to minimise drag forces.
The new stage can be combined with other Aerotech ANT series products – such as vertical lift stages, direct drive rotaries and goniometers – to create unique high-performance multi-axis nanopositioning systems.
