Ahlstrom 238: 0.34 mm – 140 mm /30 min.
This medium thick paper is recommended for general chromatography applications. Ahlstrom 238 is also ideal for use as wicks in protein or nucleic acid blotting to provide a uniform flow of buffer through the gel to the transfer membrane in a blotting sandwich. This is our most widely used blotting paper. Ahlstrom 238 is also suited for electrophoresis and the separation of inorganic compounds and for use in removing gels from glass supports.
