Hard Layer Plates• High performance silica gel providesfaster separations, higher resolution,and improved sensitivity.• Enhanced abrasion resistance offerseasier handling.• Harder surface simplifies sampleapplication.• Hard layer surface is easily written on.• Compatible with organic solvents• Faster development comparedto silica gel 60• Fluorescent plates are ideal forUV shadowingResearch is what I’m doing when Idon’t know what I’m doing.Wernher Von BraunHard Layer Silica Gel HL & HLF UNIPLATES (Organic Binder)These are the most rugged silica gel plates available. They not only easehandling and sample application, but also permit the use of up to 80%water in the developing solvent without loss of adherence of the adsorbentlayer to the glass plate. Organic binder plates are recommended for allTLC applications except those that use vigorous charring for visualization.Virtually all other visualization methods are free from interference from theorganic binder.Hard Layer Silica Gel UNIPLATES represent an advancement in thinlayer adsorbent technology. Special high performance silica gel withsmall average diameter and narrow particle size distribution resultsin separations 25% to 30% faster than with most other TLC plates.Separated spots are more compact and better resolved, which allowsvisualization at lower sample levels. The enhanced abrasion resistancemeans easier handling and sample application because plate surfacegouging is virtually eliminated. Analtech Hard Layer UNIPLATES areavailable with either organic or inorganic binders. Binder choice has littleeffect on the adsorptive properties of the adsorbent layer.Hard Layer Silica Gel HL & HLF UNIPLATES25 Plates/Box, 250 μm Thickness, 10μm particle, 60Å porePlateSize (cm)scoredchanneledpreadsorbentzonecat. no.hlcat. no.hlf20 x 20 – – – 46011 4701120 x 20 Yes – – 46511 4751120 x 20 – Yes – 46911 4791120 x 20 – – Yes 43011 4401120 x 20 Yes Yes – 46711 4771120 x 20 Yes – – 46311* 47311*20 x 20 Yes – Yes 43511 4451120 x 20 Yes – Yes 43511* 44311*20 x 20 – Yes Yes 43911 4491120 x 20 Yes Yes Yes 43711 4471110 x 20 – – – 46021 4702110 x 20 Yes – – 46521 4752110 x 20 – Yes – 46921 4792110 x 20 – – Yes 43021 4402110 x 20 – Yes Yes 43921 449215 x 20 – – – 46031 470315 x 20 – Yes – 46931 479315 x 20 – – Yes 43031 44031* Specially scored to snap to eight 2.5 x 20 cm plates16PHONE: 800.441.7540 • 302.737.6960 FAX: 302.737.7115WWW.ANALTECH.COM
