The Spinco Paper-Curtain Electrophoresis instrument lends itself to separation of all kinds of charged substances: proteins, polypeptides, amino acids and other biological materials. The unit also handles such organic substances as dyes and intermediates. In special cases, non-polar substances such as carbohydrates can be separated. The instrument is also useful in following organic reactions, and for immunochemical Avork. Design efficiency has been raised; resolution formerly requiring as much as 1500 volt operation is now made at one third this value. Paper-Curtain Electrophoresis offers this basic advantage: the processed material travels a unique path and thus absorption does not interfere with the purity of the product. Because of this, absolute separation can be made and pure fractions obtained. The new Spinco paper-curtain instru ment also has the following additional features: • • • • • • •
Easily assembled and disassembled for cleaning. Paper curtain quickly removable for oven drying. Wide range of types and thicknesses of curtains. Stability of operation permits unattended operation. Large samples processed at up to 8 milliliters per hour. Small samples processed with virtually no hold-up. Automatic tube changing permits collection of large amounts of pure material. For information request Aloe Scientific Bulletin 20-110.
