Better laboratory practices demand modern techniques in sample preparation. Our SPB series of block digestion systems offers the latest in graphite block technology – with no exposed metal components and an outer shell manufactured from acid-resistant thermoplastic, they reduce the chances of sample contamination and resist aggressive corrosion for guaranteed long life in harsh laboratory environments. Operating in conjunction with both digital and touch controllers, these sample preparation block kits feature RackLock leak-free screw caps that are easy to close with one hand, disposable watch glasses, vacuum-assisted filters that remove particulates in seconds, and one set of racks for the most effective and efficient modern sample preparation.
