1 PRINCIPLES AND PRACTICE OF THIN LAYER CHROMATOGRAPHY This experiment introduces chromatographic theory and methods of thin layer chromatography. A mixture of dyes are separated on a cellulose-based TLC plate using two different solvent systems. Kit includes: instructions, samples, reagents and solvents, cellulose thin layer plate, 5 µl glass capillary pipettes. All you need: 250ml beakers, metric rulers, pipette pump, 5 or 10ml pipettes, distilled water. For 8 Separations Spotting Plates 20 min. TLC Separation 5 min. Storage: Refrigerator Cat No. Description Price Per BIO-710-100 Thin Layer Chromatography Kit 119.00 ea. 2 TLC PLATES (POLYGRAM) With fluorescent indicator. These polyester sheets are coated with Silica 60 providing outstanding wettability and separation efficiency. Easy to cut without the silica flaking due to the excellent binding system. Can be used with ninhydrin spray. Cat No. Description Size (mm) Indicator Price Per CHR-450-100 Polygram TLC Plates 80x40 UV254nm & UV366nm 66.17 50 CHR-450-150 Polygram TLC Plates 50x200 117.88 50 CHR-450-250 Polygram TLC Plates 200x200 UV254nm 171.23 25 3 BATTERY UV LAMP - 254NM & 380NM A handheld ultraviolet lamp suitable for use with TLC plates which have UV 254 indicator, as well as for viewing certain geological mineral specimens which exhibit UV fluorescence. The UV lamp comes with both shortwave and long wave light sources: The short wave light is provided by a small tube emitting UV at 254nm and the long wave light is provided by a UV LED emitting at 380nm. Dimensions: 13 x 55 x 25mm. Requires 4x AA batteries (not included). Care: Do not look directly into UV lights and do not to expose unprotected skin to shortwave UV light. Cat No. Description Wavelength Price Per LAM-450-100 UV Lamp 254 & 380nm 50.91 ea. NINHYDRIN SPRAY Supplied in a pump action spray bottle, Ninhydrin solution is used to help visualise amino acids after chromatographic separation. Also useful for practical forensic investigations and fingerprint analysis. Cat No. Description Price Per S3203038-100ML Ninhydrin Spray 23.21 100ml
