No Mercury Touches Sample No Current Contacts Sample Collects 237 Fractions Has Wide Application
For the automatic collection of fractions by timed-flow or volumetric method. The Volumetric Collection assem bly operates as follows: (1) fraction is received in siphon and collected in reservoir; (2) pressure of frac tion elevates KHC0 3 solution in manometer to electrodes, indexing the turntable; (3) when sample is collected to siphoning level, reservoir empties into tube. Rate of flow of liquid cannot affect fraction volume. For Timed-Flow Collection, timer-controller is pre-set for desired inter val; table indexes periodically. 45291-A . . . Fraction Collector Complete, for Volume Collection; includes indexer with capacitor motor, table, volume controller, manometer, diverter, one volumetric siphon (1, 3, 5, 10, 15, or 20 m l ) , 3 base plate rod sup ports, but without support rods or clamps. For 110V. A. C. Each $457.50. 45291-B . . . Same, but for time and volume collection. Assembly has timer built into controller. Each....§533.50. For farther information request Bulletin 21-102.
