iM/jL&~L· Break the RIA,A A bottleneck. GrummanS ADP-30 Dilutor/dispenser is fast, accurateand easy-to-use. It automates many operations at very low cost. As a di lutor and/or dispenser, the ADP-30SD offers three pump configurations; 2μΙ-200μΙ, 20μΙ-100ΟμΙ, 400μΙ-20,ΟΟΟμΙ. Repro­ ducibility better than one part in a thousand. This flexibility and precision solves many difficult liquid handling problems, such as: atomic absorption, enzyme analysis reagent preparation, and repetitive and volumetric laboratory operation, including the most complex RIA protocols. With an optional dilutor, accessory, the ADP-30SD can pick up 2μΙ to 1ml and dilute with ΙΟμΙ to 20ml. Dilution ratios up to 10,000:1, depending on pump selection. The high-visibility micro­ meter volume-setting panel improves accuracy and speeds changeover. Teflon® and Pyrex®* passageways handle all fluids, eliminate contamination, facilitate cleaning. No tools required, priming is fast. Footswitch and multiplier optional. For a demon­ stration or information write: Grumman Data Systems Corporation. GDS-Î/76
