Analytical TLC UNIPLATES
GH-34105-35 Adsorbent scraper, 13 mm GH-34105-37 Replacement scraper blades, 13 mm. Pack of 5
– Choose plates with or without an acid stable fluorescent indicator.
– Snap apart evenly to facilitate single-use separations or screening
Analytical TLC UNIPLATES
Soft Layer Plates use E. Merck silica gel and CaSO4 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.
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 µL.
Preparative TLC UNIPLATES
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.

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. Tank
