Whatman has introduced a group of Mini-UniPrep Syringeless Filters. These are designed to quickly remove particles from samples in preparation for HPLC. The company said that the Mini UniPrep decreases processing time for sample batches and reduces the need for consumables.
The company is also now offering the Slit Septa Mini-UniPrep filter for robotics on HPLC instruments, and the Amber Mini-UniPrep Syringeless Filter for customers who need to protect their samples from light damage. The filters are compatible with major autosamples and are available in .2 and .45 micron pore sizes.
Spotfire said it has introduced a new version of its DecisionSite software, DecisionSite 7.3. The new DecisionSite for Functional Genomics has an ontology browser, which enables researchers to visualize genes within the gene ontology hierarchy. DecisionSite for Lead Discovery has a new capability to search chemical structures by a range of parameters, including exact match, isomer, tautomer, parent, R-group and flexmatch. Structural information, actual and virtual, can be stored along with its associated data in the SD file format, once SD files can be imported for exploring other structures. DecisionSite Posters, which allows teams to broadcast a shot of their data to other members of a project team, can now be deployed by the Sun Java System Portal Server. The new version of DecisionSite also includes an Analysis Builder feature that enables users to configure and deploy analytic applications, which now supports server deployments on Microsoft Windows NT and 2003, Sun Microsystems’ Solaris Operating System and new support for the IBM AIX and Intel based-servers running IBM’s Websphere application platform.
