Plate, Microcrystalline Cellulose, TLC, Coated on plastic sheets, 100micrometer, 20 x 20cm, 25 sheets
Biotage TLC Plates, 5cm x 10 cm Glass, with silica, 50 per cas
Biotage TLC plates are the perfect tool to predict flash methods for Biotage Sfar columns. For synthetic chemists, the benefits of matched TLC plates and flash cartridges are better purification throughput, increased compound purity and yield, and reduced solvent cost.These glass plates are coated with silica and are 5cm x 10cm packed 50 plates to a case.
Sorbent Technologies Inc Cellulose 400 TLC Plates, w/UV254, glass backed, 100um, 20x20cm, 25/pk
Cellulose 400 (microcrystalline cellulose AVICEL) with UV254, glass backed TLC plates. The coating thickness is 100um and dimensions are 20x20cm. There are 25 plates per pack. Applications include: carboxylic acids, lower alcohols, urea and purine derivatives. Cellulose 400 TLC Plates are coated with microcrystalline cellulose AVICEL. This type of cellulose is prepared by hydrolysis of high purity cellulose with hydrochloric acid. Depending on the starting cellulose and the following clean-up, one obtains cellulose crystallites with a mean degree of polymerization between 40 and 200. The microcrystalline structure of this cellulose can be confirmed by X-ray investigations.
Sorbent Technologies Inc Silica XHL TLC Plates, glass backed, 250um, 20x20cm, 25/pk
"Silica XHL" 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. This analytical extra hard layer is bound to a glass support. It has a thickness of 250um and dimensions of 20x20cm. There are 25 plates per pack. The layer has an outstanding hardness and is abrasion resistant due to an optimized binder system. The plate can be easily labeled with a lead pencil for clear identification. There is an increased separation efficiency due to an optimized particle size distribution.
Sorbent Technologies Inc Silica Chiral, w/UV254, glass backed, 250um, 10x20cm, 4/pk
Chiral TLC plates are coated with a reversed phase silica gel, and impregnated with a chiral selector (a proline derivative, DP 31 43 726 and EP 0 143 147) and copper(II) ions. This plate allows for multiple simultaneous separations, a great advantage for routine applications and production control. 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 10x20cm. There are 4 plates per pack. Applications include: enantiomer separation of amino acids, N-methylamino acids, N-formylamino acids, a-alkylamino acids, thiazolidine derivatives, dipeptides, lactones, a-hydroxycarboxylic acids
Sorbent Technologies Inc Alumina N TLC Plates, w/UV254, polyester backed, 200um, 2.5x7.5cm, 200/pk
Alumina Neutral (pH 6-8) with UV254, analytical, polyester backed TLC plates. The coating thickness is 200um and dimensions are 2.5x7.5cm. There are 200 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.
