We've had the most compact fraction collector all along, but we've never bragged about it. We would rather tell you about our Model AT's reliability, and how versatile it is. You can choose from seven combinations of time and volumetric control and add on later if you change your mind. Lift-off reels hold up to 180 test tubes or 90 scintillation vials. You don't have to put the con­ troller under the drive base. If you are in a cramped cold room, you can put it on a shelf, under the work table, or even outside. ISCO has complete fraction col­ lectors from $220.00. Send for brochure FC31F.
