Polygram Pre-Coated T.L.C. Plates
Product Code : EL-CA-11571
The Polygram Pre-Coated TLC Plates are thin-layer chromatography plates used for separating, comparing, and observing components of mixtures in supervised school and college chemistry laboratories. They are suitable for chemical analysis practicals, organic chemistry demonstrations, teaching labs, distributors, and institutional procurement teams.
Product Description
Polygram Pre-Coated T.L.C. Plates from School Equipments India are listed with product code EL-CA-11571. The plates are coated with silica gel and include a fluorescent indicator. The confirmed sheet size is 40mm x 80mm, with a listed layer thickness of 0.25mm.
These TLC plates are intended as general-purpose plates suitable for most separations. The carrier sheet is polyester, listed as 0.2mm thick, and resistant to organic solvents used in T.L.C. The plates can be cut with scissors and rolled to fit into chromatography cylinders. The listing states an average pore diameter of 6mm; verify this unit before publishing final technical copy.

How to Use the Polygram Pre-Coated T.L.C. Plates
- Handle the plate by the edges to avoid contaminating the silica gel surface.
- Mark a light pencil baseline near the lower edge of the plate.
- Apply a small sample spot using a capillary tube or approved spotting method.
- Place the plate in a chromatography chamber containing a suitable solvent system.
- Keep the sample spot above the solvent level.
- Allow the solvent front to rise until the required development height is reached.
- Remove the plate, mark the solvent front, and allow it to dry safely.
- Visualise spots using the approved method, such as UV viewing or staining where suitable.
Safety note: Use only under teacher or laboratory-supervisor control. Do not inhale solvent vapours, touch the coated surface unnecessarily, use open flames near solvents, or view UV plates without suitable eye and skin protection.
Care & Maintenance
- Store plates dry, flat, and protected from dust, moisture, and solvent vapours.
- Keep plates in closed packaging until use to protect the adsorbent layer.
- Cut plates only with clean scissors and avoid damaging the coating.
- Discard plates with scratched, contaminated, wet, or flaking coating.
