Berghof 'speedwave® four' microwave digestion system - uncomplicated and straight forward digestions. Speedwave makes laboratory work easier and safer. Very easy handling thanks to the top loading concept. The entire, heavy rotor no longer needs to be lifted and placed in the microwave oven. It remains in the oven chamber and the vessels are simply inserted individually and removed again after digestion. The heated vessels…

digestec DAB-2/3, to Digest the Hardest Samples. The traditional “stainless steel bomb” with its PTFE insert is being increasingly replaced by the microwave for most routine applications. However, when it comes to difficult-to-digest samples such as silicon carbide or alpha-aluminium oxide, such systems remain of inestimable value to users. The great advantage of these systems lies in the fact that the digestion period can…

96-well filter plate designed and optimized for aqueous solubility assaysDetermining a compound's aqueous solubility has become an essential early measurement to make in the drug discovery process. Poor water solubility can cause problems in many different in vitro testing techniques leading to unreliable results and/or reproducibility problems; insoluble precipitates have been shown to cause false positives in bioassays poten…
