Wassermann reactions simplified.

Most techniques at present in use for the Wassermann reaction require a great deal of bench and water bath space, are very time consuming, and put a considerable burden on those responsible for the preparation of glassware. The use of moulded perspex plates (M.R.C. pattern)* in this laboratory has cut down immensely the space and labour involved in doing routine Wassermann reactions, and has added considerably to the pleasure in their performance. The plates are easy to handle, no racks are required and each plate, equivalent to 80 test tubes, is washed in a few seconds. This note is submitted in the hope that others may be persuaded to review their present techniques and to consider changing or adapting them for use with
