These tlc plates combine top-quality adsorbents, consistent manufacturing, rigid QC, and careful packaging-thee results of 40 years of experience dedicated to thin layer techniques. Select the perfect analytical plates for your application. Choose plates with or without an acid stable fluorescent indicator (UV 254 nm). scored plates snap apart evenly to facilitate single-use separations or screening. Reversed phase plates use a readily removed nonpolar adsorbent — hydrocarbon-impregnated silica. Efficient separations — economically!
