For Preparative Electrophoresis on Gels...
New Automatic Electnophonatic Eluton
BUCHLER FRACTDPHORATOR N o w Y o u C a n Use A l m o s t A n y G e l . . . Any B u f f e r . . . Any F r a c t i o n C o l l e c t o r ! The Fractophorator, for disc electrophoresis, is designed f o r the separation of proteins, hemoglobin, albumin, enzymes and other compounds, using polyacrylamide or any other supporting medium. It automatically elutes in pre-determined amounts of buffer solution, individual bands emerging from the electrophoretic column and delivers the fractions t o a collector. The complete unit can be attached to any electrically driven fraction collector and is activated by the collector's t i m i n g system. Load capacity is from a few micrograms to 25 mgm in a 13mm diameter by 130mm long column. Price: $570.00 Fractophorator is shown with Buchler Fractomette 200 Fraction Collector.
