β¦ Synopsis
Conventional methods for dialyzing numerous samples are either expensive or tedious and inefficient. These disadvantages were overcome through the construction and use of a Plexiglas dialysis sample holder (DSH). Large numbers of dialysis samples having 0.5 to 2.0-ml volumes may be attached to numbered positions on the DSH. Sample identification is greatly simplified and considerable savings in time and material are achieved. Furthermore, the risk of sample spill or mixing during filling or emptying of dialysis sacks, and the risk of leaks in dialysis tubing, are minimized.

Desalting of nucleic acids by the drop dialysis method is limited by the fact that only small volume samples can be used due to the lack of sample containment on the membrane filters. A specially modified Styrafoam cup can be used as a membrane filter holder which serves to contain the sample, thus
