TLC Plates
Sorbent Technologies Inc C2 Silica TLC Plates, w/UV254, glass backed, 250um, 20x20cm, 25/pk
This thin layer chromatography (TLC) plate comprises a C2 Silica layer. It can be developed with purely organic, organic/aqueous and purely aqueous eluents. Thus the phase finds numerous applications in normal phase chromatography as well as in the reversed phase mode. The relative polarity of the eluent determines the polarity of the layer. The Silica 60 has a surface area of 500 m2/g, mean pore size of 60A, specific pore volume of 0.75 ml/g, particle size of 5-17um, and pH stability of 2-10. The TLC plates contain UV254 fluorescent indicator. The UV-absorbing substances appear as dark-blue to black spots on a light - blue background. This analytical layer is bound to a glass support. It has a thickness of 250um and dimensions of 20x20cm. There are 25 plates per pack. Applications include: active plant constituents, steroids
Miles Scientific SILICA GEL GF 250UM 20X20CM SCORED & CHANNELED (25 PLATES/BOX)
Silica Gel G & GF UNIPLATES are the most widely used silica gel TLC plates. No organic substances are added to these products, thus making them compatible with sulfuric acid charring visualization. These plates are commonly scraped from the glass backing to isolate separated components for other analytical procedures. They are compatible with all organic solvents, however, they are not recommended for use in systems containing greater than 20% water because of the solubility of the gypsum binder in aqueous solutions. (For water tolerance see the GHL & GHLF series of plates.)

Silica Gel F coated on Plastic Sheets 200um 5x20cm (50 sheets)
Sorbent Technologies Inc Silica XG TLC Plates, w/UV254, aluminum backed, 200um, 5x10cm, 50pk
"Silica XG" is a standard grade Silica 60 with a surface area of 500 m2/g, mean pore size of 60A, specific pore volume of 0.75 ml/g, and particle size of 5-17um. The TLC plates contain UV254 fluorescent indicator. This analytical soft layer is bound to an aluminum support. It has a thickness of 200um and dimensions of 5x10cm. There are 50 plates per pack. The Silica XG TLC Plate has outstanding wettability for precise colorization results, even with 100% aqueous detection reagents, and excellent separation efficiency and reproducibility from lot to lot. Cutting the plates is easy and reliable due to an optimized binder system. There is no flaking of silica gel layer. Binder: highly polymeric product, which is stable in almost all organic solvents and resistant towards aggressive visualization reagents; also completely stable in purely aqueous eluents.
Miles Scientific RP-2 Dimethyl Silanized Silica Gel 60 F on Glass 250U 20X20CM (25 PLATES)
RP-2 dimethyl-modified Silica Gel 60 - fluorescent indicator (UV 254) - Glass-backed - 250 µm thickness - 20x20 cm - 25 plates per box This TLC plate can be developed using purely organic, organic/aqueous, and purely aqueous mobile phases. Due to this these plates have been used in numerous applications in normal phase chromatography as well as reversed phase chromatography. Common applications include the analysis of active plant constituents and steroids.
Miles Scientific Silica Gel G 250um 20x20cm (25 plates/box)
No organic substances are added to these products, thus making them compatible with sulfuric acid charring visualization. These plates are commonly scraped from the glass backing to isolate separated components for other analytical procedures. They are compatible with all organic solvents however, they are not recommended for use in systems containing greater than 20% water because of the solubility of the gypsum binder in aqueous solutions. The "G" stands for Gypsum and indicates that calcium sulfate hemihydrate (CaSO4·1/2H2O), a refined form of gypsum, has been included in the adsorption formulation. Gypsum functions as a binder, improving the cohesion of the adsorbent particles and increasing the adhesion of the layer to the glass substrate.
Sorbent Technologies Inc Silica G Prep TLC Plates, w/UV254, glass backed, 20x20cm, 1000um, 15/pk
"Silica G" is a standard grade, unmodified Silica 60 with a surface area of 500 m2/g, mean pore size of 60A, specific pore volume of 0.75 ml/g, and particle size of 5-50um. The plates contain UV254 fluorescent indicator. This preparative soft layer is bound to a glass support. It has a thickness of 1000um and dimensions of 20x20cm. There are 15 plates per pack.
Sorbent Technologies Inc Cellulose 300 TLC Plates, polyester backed, 100um, 5x20cm, 50/pk
Cellulose 300 polyester backed TLC plates. The coating thickness is 100um and dimensions are 5x20cm. There are 50 plates per pack. Applications include: partition chromatography of polar substances such as amino acids, carboxylic acids or carbohydrates. Cellulose is especially used for partition chromatographic separations of polar substances such as amino acids and other carboxylic acids or carbohydrates. Compared to paper chromatography (PC) thin layer chromatography, cellulose offers shorter migration times and more concentrated substance spots resulting in a higher detection sensitivity. TLC plates (CEL 300) are coated with native, fibrous cellulose.
