What are the advantages of the Lachat BD-46 over other blocks in the market?
Maximize accuracy and precision Because the BD-46 has 46 tube positions rather than the usual 40, calibration standards can now be carried through the same digestion process as the samples. This maximizes accuracy and precision since the standards and samples are treated exactly the same. Reduce overflow of samples with surfactants Many discharge water samples contain varying levels of surfactants, which will cause foaming of the sample during digestion. The foam may then overflow from the tube onto the heated block. The special design of the BD-46 digestion tube incorporates a bulb towards the top, which breaks up most foam and reduces overflow. Eliminate the need for expensive acid scrubbers Until the BD-46, acid fumes have presented a serious problem. Either an expensive and often ineffective acid scrubber needed to be purchased or the unit needed to be in a hood where corrosive fumes would attack the seals and significantly shorten the life of the hood. Now, with the addition of an
