Sorbent Technologies Inc Alumina N Prep TLC Plates, w/UV254, glass backed, 1000um, 20x20cm, 15/pk
Alumina Neutral (pH 6-8) with UV254, preparative, glass backed TLC plates. The coating thickness is 1000um and dimensions are 20x20cm. There are 15 plates per pack. Applications include: terpenes, alkaloids, steroids, aliphatic and aromatic compounds. To ensure sufficient adherence an inert organic binder is added to the aqueous suspension for coating. The aluminum oxide layer has a specific surface of about 200 m2/g (BET) and a pore size of about 60A. To activate the aluminum oxide layer, we recommend heating the TLC plates for 10 minutes at 120C.
Sorbent Technologies Inc Silica G Prep TLC Plates, w/UV254, glass backed, 20x20cm, 500um, 20/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 500um and dimensions of 20x20cm. There are 20 plates per pack.
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
Sorbent Technologies Inc Alumina N TLC Plates, w/UV254, polyester backed, 200um, 4x8cm, 50/pk
Alumina Neutral (pH 6-8) with UV254, analytical, polyester backed TLC plates. The coating thickness is 200um and dimensions are 4x8cm. There are 50 plates per pack. Applications include: terpenes, alkaloids, steroids, aliphatic and aromatic compounds. To ensure sufficient adherence an inert organic binder is added to the aqueous suspension for coating. The aluminum oxide layer has a specific surface of about 200 m2/g (BET) and a pore size of about 60A. To activate the aluminum oxide layer, we recommend heating the TLC plates for 10 minutes at 120C.
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.
