Spinco

CONTINUOUS FLOW

Electrophoresis

Apparatus

* High resolution,flexibility andefficiency

* Precisely controlledsample feed andelectrolyte flow

CONTINUOUS FLOW PAPER ELECTROPHORESISAPPARATUS, Spinco Model CP (Patented). A newdesign which offers improvements in flexibility andefficiency, and permits separations not heretoforepossible. New methods of electrolyte feed and wide-range controls permit the instrument to give maxi-mum throughput under any required degree ofresolution. Design efficiency permits resolutionsformerly requiring as much as 1500-volt operationto be made at one-third this value.

Controls permit precise adjustment of feed pointand positioning and orientation of the pattern.Large-volume vertical wicks between the curtainand electrode vessels provide optimal distributionof the electrical field and prevent migration intothe paper curtain of electrode products.

Applicable to the separation of all kinds ofcharged substances such as proteins, polypeptides,amino acids and other biological materials. Alsosuitable for organic substances such as dyes andintermediates. Particularly useful for following or-ganic reactions and for immuno-chemical work.

Paper curtain electrophor-esis offers the basicadvantage that the sample travels a unique pathand thus adsorption does not interfere with thepurity of the product. Absolute separations can

therefore be made. Advantages of this new designare:

Easily assembled and disassembled for clean-ing.

Stability of operation permits unattended runsof indefinite duration.

Paper curtains are quickly removable for ovendrying in analytical applications.

A wide range of types and thicknesses ofcurtains can be used.

Large samples can be processed at through-puts up to 8 ml per hour, small samples withvirtually no hold-up.

A specially designed pump circulates buffer,or recirculates, if desired, permitting locationof reservoirs below the apparatus.
