Explore MoreFREE SAMPLE TLC STRIPS AND FORCEPS INCLUDED WITH PURCHASE. 12/23/2022: Grounded joint is lightly pre-greased for a smoother feel. Vapor will be well sealed with or without vacuum grease, so grease does not necessarily need to be reapplied. Glass jar/tank for TLC development purposes. Will comfortably fit in TLC strips for elution. The grounded joint lid will keep your solvent vapor fully contained and saturated inside. The cylindrical shape of the bottle will make it easier for the user to remove the TLC plate with a pair of forceps after development, compared to a rectangular or square interior. Inner diameter 4.5 cm, inner height 6/7.5/9 cm. See photos for more measurements. The 6 cm jar will fit up to 6.5 cm long TLC plates. (Discontinued)The 7.5 cm jar will comfortably fit up to 2.5 cm x 8 cm, or 3 cm x 7.5 cm TLC plates. The 9 cm jar will fit up to 8 cm x 3 cm TLC plates. (Discontinued, but available upon request)See photos for demonstration. Can also be used for multi-purpose general storage.

Explore MoreClassic Preparative TLC Plates. Silica Gel 60 F254 type. 20x20cm plate size, 1mm (1000μm) silica layer thickness. pH 6.2-6.8, particle size 10-40 μm, pore size 60 Å. 8 glass plates per box. A test run separating dimethyl maleate and dimethyl fumerate has been performed and shown in photos. 50mg of each compound (total mass 100mg), dissolved in a small amount mixture of hexane, acetone and dichloromethane was spotted onto the plate. The plate was eluted twice with hexane:acetone=15:1, giving a very good separation. While this is expected, this also indicated that depending on how far away each component band is on TLC, one can load material amounts of 100mg and more onto the plate since in the example the plates have not quite reached full capacity. The preparative TLC method is an alternative to preparative HPLC. HPLC methods can be more expensive and due to the column being constantly reused, contamination can occur. Prep TLC is especially suitable for applications when there is relatively a small amount of sample, and purity requirements are high, and when at the same time the researcher is looking for a quick, convenient and economic way of purification.

Explore MoreClassic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 Å pore size. Aluminum backed-easily cut by a pair of scissors. What’s ideal is that these plates have neutral silica (pH 6-7) instead of the more common acidic silica (pH=5) for TLC silica plates. The neutral silica make the plates compatible with running compounds with an amino group even without the need of adding triethylamine. At the same time non-amino compounds behave the same as on acidic TLC plates. Actual examples performed with the plates have been uploaded for users to see.In listing photo 6 (or below), highly similar diethyl maleate and dimethyl maleate are spotted on the plates and eluted with different ratios of ethyl acetate : hexanes, showing a gradual change of Rf.
