Here are two compact, versatile fraction collectors designed to do a big job in a small space. The "Fractomette 200" uses 200 18 mm O.D. test tubes while the "Fractomette 4 0 0 " has a capacity of 400 tubes. Both fraction collec tors provide drop, time and volume methods of collection. Fractions dispense directly into the tubes preventing cross-conta m ination.The "Fractomette 200" measures only l l > / 2 " x 17V 2 "; the "Fractomette 400" is 17"/ 2 " χ 2 4 i / 2 " .
