PerkinElmer - Sample Preparation Block Systems

PerkinElmer offers a variety of sample preparation blocks and accessories for your lab needs. Better laboratory practices demand modern techniques in sample preparation. In the past, hot plates were used to digest samples where common digestion problems involved rusting, cross contamination of digestion system to sample, and poor sample temperature control. With no exposed metal components and an outer shell manufactured from acid-resistant thermoplastic, the SPB blocks reduce the chances of sample contamination. Each system is constructed with a solid, Teflon-coated, graphite block where a flat heater covers 95% of the block’s base. This guarantees temperature uniformity and eliminates hot spots found in hot plates.
