N o lubricants, for instance, are required in these Separatory Funnels. This means that you can now handle any material heretofore sensitive t o this substance. Acids, alkalies and other reagents will not cause them to stick. Without lubricants t o dissolve, there is also freedom from troublesome leakage.

The smaller sizes of funnels (30 t o 125 m l ) are especially adaptable for centrifuging to speed up separations, and t h e valve is so designed t h a t it is completely locked in during this process. The K-4525 series, cylindrical type, 30 m l . , is ideal for vitamin analysis.

It 'will pay you well to investigate KONTES' FUNNELS today.
