EMD Millipore® TLC Chromatography Plates
Unique quality from the pioneer in thin layer chromatography (TLC), these chromatography plates are a simple, fast and highly versatile separation tool for qualitative and quantitative analyses. TLC can resolve virtually all classes of substances, including pesticides, steroids, alkaloids, lipids, nucleotides, glycosides, carbohydrates and fatty acids. EMD Millipore® TLC plates can be used in classic manual TLC, automated instrumental high-performance TLC and preparative liquid chromatography. The disposable glass-backed silica-absorbent plates are treated with green fluorescent dye to ensure simplified sample preparation and direct visualization of colorless substances in the UV range (at 254 nm) or derivatization and allow simultaneous analysis of multiple samples under identical conditions with easy, two-dimensional separation. Measure 2.5 × 7.5 cm with a thickness of 250 μm. Particle size: 10–12 μm. Package of 100.

Thin Layer Chromatography Sheet
Thin layer chromatography (TLC) is becoming more and more popu- lar in Advanced Placement and Honors Chemistry courses. Until now you’ve had to purchase a tremendous quantity of TLC sheets at a price that would wipe out your budget. No longer—Flinn offers a single 20 × 20 cm flexible sheet with a 200 micrometer layer of silica gel. This sheet will provide forty 2 × 5 cm strips—more than enough for a few labs.

Kimble® TLC Spotting Capillaries
Microcaps® are precision-bore glass capillary tubes, cut to predeter- mined lengths so each capillary tube will hold a known volume of fluid when filled. Microcaps® are inexpensive and can be disposed of after use. Filling is simple and no unusual skills or training required for immediate, professional results. Supplied in packages containing one bulb assembly and one dispenser vial with 100 micropipets.

Chromatography Jar and Lid
Just what you need for your chromatography labs. Jar has a capacity of 480 mL. 51⁄4" H x 31⁄8" dia. x 21⁄8" mouth. Includes lid.
Sigma-Aldrich TLC Development Chamber
Novel horizontal chambers permit the rapid screening of column chromatography fractions. Designed for economy and use in student laboratories.
Use with 25 × 70 mm flexible plastic or glass thin-layer chroma- tography (TLC) plates that may be spotted with up to ten fractions 7 mm apart along the long edge of the plate. Uses only 2 mL of solvent with elution complete in about 45 seconds. Greater resolution may be achieved by extending elution time.
