✦ Synopsis

Sterilizing the Bacteriological Loop During Phenol Coefficient Determinations.--RoBERT K. JENNINGS AND C. H. LUDWIG. Rapid transfer of cultures at specified time intervals, as in phenol coefficient tests which require that a fresh transfer be made every thirty seconds, is greatly facilitated by the use of the device illustrated. When so short a time is allotted to each transfer there is some danger of skimping on the time required for sterilization of the wire or of not permitting it to cool sufficiently. The apparatus shown in use automatically regulates the time of heating and cooling the loop, while actually shortening the time required for this manipulation, as far as the operator is concerned.
