SILICA GEL H W/ 5% AMMONIUM SULFATE 500UM 5X20CM (25 PLATES/BOX) P74032

Silica Gel H Uniplates containing ammonium sulfate eliminate the need to use messy sulfuric acid for charring.  Just evaporate the developing solvent until the plant is completely dry, then heat at 150- 200 degrees for 30-60 minutes to achieve charring.

·Excellent for visualizing organic compounds on a silica gel TLC Plate is charring
·Organic substains will appear to be brown to black against a white background
·The method is comparable in sensitivity to the visualization of UV-absorbing compounds against a fluorescent background
