Chromatography Need help selecting? Free Tech Support ! Glass-Backed TLC Plates Get efficient separations— economically Analytical TLC Plates - Choose plates with or without an acid stable fluorescent indicator. - Snap apart evenly to facilitate single-use separations or screening Analytical TLC Plates Soft Layer Plates use E. Merck silica gel and CaS04 binder for general organic separations. Not recommended for solvent systems >20% water. Hard Layer Plates with Organic Binder use proprietary silica to enable separations using solvent media up to 80% water. Hard Layer Plates with Inorganic Binder have a hard proprietary silica layer and are recommended for charring visualization applications. Plate size Plate size Reversed Phase Plates have a nonpolar adsorbent— hydrocarbon-impregnated silica. HPTLC Plates achieve fast, high-resolution separations using proprietary silica. Recommended for sample sizes <1 pL. Preparative TLC Plates Soft Layer Plates use E. Merck silica gel and CaSO4 binder for general organic separations and easy scraping. Reversed Phase Plates use a readily removed nonpolar adsorbent—hydrocarbon-impregnated silica. GY-34105-35 Adsorbent scraper, 13 mm GY-34105-37 Replacement scraper blades, 13 mm. Pack of 5 Tank 34105-20 Glass TLC Developing Tanks Optimize your plate development - Accommodate standard TLC plates The top surface is ground to a precise tolerance for tight sealing to enable tank saturation and optimal plate development. Thinline™ tanks accommodate two plates and require less solvent for development. Latch-Lid™ units hold lids in place with stainless steel latches.
