INSTRUMENTATION

LUBRICANT F&P UI trama χ SEPARATORY FUNNEL

Now — from the laboratories of Fischer & Porter, comes the new F&P-developed Class Separatory Funnel. With the new stopcock, lubrication and freezing problems are ended. Gone are costly leakages and blowouts during centrifuging. Product contamination is completely avoided.

Note the unconventional design of the F&P Separatory Funnel. The Ultramax* valve consists of a plug of Teflonf turning on a natural glazed surface of unground, precisely-formed Pyrex$ tubing. Complete in-te rchangeabi l i ty of pa r t s , all cor ros ion-resistant, makes replacement easy.

Funnel sizes available range from 30 ml to 2 liters, and come in the globe, squibb or cylindrical type. Smaller sizes — 30 ml to 125 ml — are especially adaptable for centrifuging. Cylindrical type, 30 ml, is perfect for vitamin analysis.

Complete details are yours for the asking. Or test the new F&P Separatory Funnel in your own laboratory for 30 days without cost. Write today!
