Pyrosequencing Extends Vacuum Prep Tool Capabilities and Introduces new Accompanying Workstation


UPPSALA, Sweden, Feb. 26, 2003 (PRIMEZONE) -- Pyrosequencing AB (Stockholm:PYROA) (Other OTC:PYRSF) today announced that the acclaimed Pyrosequencing(TM) Vacuum Prep Tool is now available for all 96-well format Pyrosequencing genetic analysis systems -- extending the benefits of batch processing 96 post-PCR samples in less than 15 minutes to PSQ(TM)96MA and PSQ(TM)96 System customers. The Vacuum Prep Tool is also more cost-effective due to doubling the life of the 96 filter probes within the hand-held device. Sample preparation convenience and workflow ergonomics are further improved with the introduction of the new accompanying Vacuum Prep Workstation. The bench-top Workstation consists of a Vacuum Prep Tool in combination with the new Worktable, which contains strategically placed solution troughs, an integrated vacuum pressure gauge and a storage position for the Vacuum Prep Tool. The new Worktable is available as an upgrade package for previously purchased Vacuum Prep Tools.
