New 1.3-Micron Core-Shell Media Delivers Superior UHPLC Performance


Phenomenex Inc announces the addition of 1.3-micron UHPLC columns to its Kinetex core-shell product line. With the smallest diameter in the Kinetex family, the 1.3-micron is the most efficient particle on the market, delivering measurably better performance than conventional fully porous media on UHPLC equipment. The Kinetex core-shell family now includes four particle sizes, from 1.3- to 5- micron, providing separation solutions for virtually every chromatographic application and easy method transferability from UHPLC to HPLC to preparative-scale LC.


“The Kinetex product line spans our customers’ needs, from sub-2-micron UHPLC to small-scale purification, enabling everyone to take advantage of the performance and productivity gains that core-shell technology can deliver,” commented Simon Lomas, Brand Manager for Phenomenex.


The TriopackTM from Socorex is a ready to use set including three Acura® sample of Qualitips®


With efficiency levels over 400,000 plates per meter, the Kinetex 1.3-micron represents a dramatic advancement in LC media technology. UHPLC users can now reach previously unavailable levels of sensitivity and performance, with the added benefit of easy method transferability and scalability to any of the three other Kinetex particle sizes. While fully porous sub-2-micron columns exhibit significant band broadening due to frictional heating as flow rate increases, the Kinetex particle morphology and packing technology help to reduce these and other effects to ensure high resolution and sensitivity over an extended linear velocity.

operating instructions. There are nine different packs available, each covering specific volumes. From molecular genetics to environmental analytics, this selection of micropipettes provides convenient instrument combinations for any laboratory needs. TriopackTM


Phenomenex core-shell products meet researchers’ need to improve results and increase productivity with their current instrumentation. By delivering significant improvements in speed and separation power over traditional fully porous columns, Kinetex columns enable chromatographers to get superior results on any LC or UHPLC platform, along with potential reductions in solvent usage.

The Combipack™ is Porvair Sciences economic response to the growing use of protein precipitation separation techniques in chromatography labs. Comprising four Porvair p3 protein precipitation plates and four 1ml deep well collection plates (colour coded in red or blue polypropylene) the Combipack provides all the elements you require to undertake protein precipitation separations at a very affordable price.


New Range of Pipette Controller Filters Available


Based upon the industry standard MicroLute™ 96-well format, the p3 plate uses the CRASH method in which protein in samples is denatured with acetonitrile and the flocculent filtered out. A novel dual filter matrix retains sample in the wells of the p3 plate until required to release by vacuum or pressure.


The use of a prefilter on top of an oleophobic filter eliminates blockages commonly found with other protein precipitation plates especially when handling high protein samples. The p3 has been proven in independent tests to eliminate the mess and complex sample preparation (no centrifuging, no vortexing) traditionally associated with protein precipitation techniques. Manufactured to the standard ANSI/SBS footprint all plates in the Combipack are fully automation compatible.

New Cuvette Allows Life Scientists to Analyse Even Smaller Sample Volumes


Eppendorf has introduced the new Eppendorf µCuvette G1.0, designed for the accurate and reliable measurement of small volumes of highly concentrated biomolecules, such as proteins and nucleic acids. Users can work easily with samples as small as 1.5µL without the need for a time-consuming dilution step. The µCuvette G1.0 expands the measuring range of the Eppendorf BioPhotometer and the Eppendorf


BioSpectrometer. Synchronised apertures mean that a closed system is created when used alongside Eppendorf detection instruments, for optimum results and reliable operation.


Filter Devices are delighted to offer a range of pipette controller filters, ideal for use in laboratory and cleanroom environments where quality control of potential cross contamination is a high priority.


Using their expertise in producing custom made in- line filtration devices, their new 24mm pipette


controller filters contain a 0.2ųm or 0.45ųm hydrophobic membrane accommodated in a housing tested to exacting standards. Ensuring high performance for the user and a quality delivered product every time, Helapet provide batch coding for full traceability.


Offered with Male Slip Luer connectors, the new 24mm Pipette Controller filters can securely fit into a majority of pipette controller models. Filter Devices also offer its quality Varidisk®


service allowing the


flexibility to respond quickly, and hold stock for next day delivery. Whether you wish to have OEM filters individually custom printed with your brand, individually or bulk packed, Filter Devices can provide the best solution.

“Photometric measurements are only as accurate as the device and corresponding accessory,” said Dr Tanja Musiol, Global Product Manager Detection at Eppendorf AG. “Selecting the perfect cuvette is just as important as choosing the right device. Higher sample concentrations


require a shorter optical path length for measurement. The optical path length of the µCuvette G1.0 is just 1mm, ten times shorter than the light path length of standard cuvettes. This provides a better system for measurements at high concentrations.” Eppendorf has a worldwide reputation as producers of premium laboratory equipment. The µCuvette G1.0 expands the company’s extensive range of products for micro- volume applications.

The Discovery Pro pipette from Labnet is equipped with a series of ergonomic improvements not found on traditional models. An updated soft-touch plunger system ensures light aspiration and dispensing forces, while a levered ejection mechanism is designed to provide smooth and gentle tip ejection. The volume adjustment wheel is conveniently located just beneath the plunger button and requires minimal force to select the desired volume. To prevent accidental volume changes, the adjustment wheel can be set to a locked position by pressing it downward.


The pipette handle combines a modern design and innovative construction which provide thermal insulation of the internal parts. The Discovery Pro is made of the highest quality grade materials to guarantee the best chemical and mechanical resistance and enables sterilisation under UV light and by autoclaving.


A four-digit counter allows for fine control over volume adjustment and is located on the palm side of the device, facing the user at all times.
