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.)

Miles Scientific Silica Gel GHLF 250um 10x20cm scored (25 plates/box)
Plates are 100% H20 resistant and are compatible with aqueous developing solvents. They are less rugged than the plates with organic binder but still provide improved handling and sample application compared to Silica Gel G UNIPLATES and are tough enough to write on with a soft pencil. Hard Layer UNIPLATES with inorganic binder are recommended for all applications including those where visualization occurs involving strong charring procedures or acid sprays or dips. Layers tolerate 100% water. Contains no organic materials, Suitable for aggressive visualization procedures, Standard scoring for 20x20 cm plates yields four 5x20 cm plates, One box of scored 10x20 cm plates yields two hundred 2.5x10 cm plates.

Miles Scientific SILICA GEL W/AGNO3 250UM 20X20CM (25 PLATES/BOX)
These silver nitrate impregnated silica gel plates are for argentation chromatography. They are impregnated with between 5% and 20% silver nitrate which modifies the separation characteristics of the adsorbent layer to permit increased discrimination of certain compounds, particularly those containing carbon-carbon double bonds. They are available with or without a fluorescent indicator. NOTE: The concentration of silver nitrate (5, 10, 15, or 20%) must be specified at the time of order. The most common concentration is 10%.
Miles Scientific RP18F ON GLASS 250UM 20X20CM (25 PLATES)
Reversed Phase Octadecyl Silanized Silica Gel. These reversed phase TLC plates have been manufacturer to be greater than 50% and less than 100% silanized. Because of this they are hydrophobic, but wettable (unlike CAT# 164077 & 165077 which are 100% silanized). FEATURES: 14% carbon content - Acid stable (UV254) fluorescent indicator - 20x20 cm glass backing - 250um coating thickness - 25 plates/box - Recomended Applications: aminophenols, barbiturates, preservatives, nucleobases, polycyclic aromatic hydrocarbons, steroids, tetracyclines, plasticizers (phthalates)

NC2468097 SILICA GEL HLF 250UM 2.5X7.5CM
Sorbent Technologies Inc Cellulose 300 TLC Plates, aluminum backed, 100um, 4x8cm, 50pk
Cellulose 300 aluminum backed TLC plates. The coating thickness is 100um and dimensions are 4x8cm. 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.
Sorbent Technologies Inc Cellulose 300 PEI TLC Plates, polyester backed, 100um, 20x20cm, 25/pk
Cellulose 300 PEI, polyester backed TLC plates contain fibrous cellulose impregnated with polyethyleneimine. The coating thickness is 100um and dimensions are 20x20cm. There are 25 plates per pack. Applications include: analysis of nucleic acids, and of mutagenic substances with the 32P post-labelling procedure (see Sorbtech Application No. 402260.) Cellulose ion exchange layers are suited for the separation of substances with exchange-active groups. Consequently they are used for the separation of amino acids, peptides, enzymes, nucleic acid constituents (nucleotides, nucleosides) etc. PEI is not a chemically modified cellulose, but a complex of cellulose and poly- ethyleneimine. PEI cellulose is a relatively strong anion exchanger. PEI layers should be stored in a refrigerator at 4C. An important application of CEL 300 PEI is the analysis of mutagenic substances with a 32P postlabelling procedure.
