BUCHLER INSTRUMENTS' " FRACTOMETTE 2 0 0 " Buchler Instruments' new "Fractomette 200" is the world's most compact 200 tube (18 mm diameter) linear fraction collector. Only IIV2" wide, the "Fractomette 200" saves valuable bench space, yet offers features not found in many of the larger units on the market. It provides drop, time and volume (syphon or photoelectric) collection directly into tubes preventing cross-contamination. Π The "Fractomette 200" will operate at normal temperature, in a refrigerator or in a cold room. Other features include: drop-stop to prevent stray drops or loss of samples; shuts off after predetermined number of tubes are collected; special rack adapters to permit micro-collection; change racks
