These plates are 100% H20 resistant and are compatible with aqueous developing solvents. They are less rugged than the plates with organic binder but still provide improved handling and sample application compared to Silica Gel G UNIPLATES and are tough enough to write on with a soft pencil, if...
When using thin layer or paper chromatography (TLC), these borosilicate glass atomizers are used for spraying chromogenic reagents. Complete unit consists of spray head, flask, and LG-1004 clamp. The air inlet tube has an opening to release pressure and stop spraying. All joints are Standard Taper...
Silica Gel G & GF UNIPLATES are the most widely used silica gel TLC plates. No organic substances are added to these products, thus making them compatible with sulfuric acid charring visualization. These plates are commonly scraped from the glass backing to isolate separated components for other...

Features Base material: Nano-silica 60, specific surface (BET) ~ 500 m2/g, mean pore size 60 Å, specific pore volume 0.75 mL/g, particle size 2–10 μm, pH stability 2–10 Partial (50%) or complete (100%) octadecyl modification, carbon content 7.5 and 14%, respectively Indicator:...
Flat ground top is beveled on the inner and outer rim Ground flat bottom for stability Holds two 10 x 10 cm plates or four 5 x 10 cm plates Thin-Line units allow for faster and more uniform solvent saturated atmosphere and therefore require less solvent. Inside dimensions: 12 x 6.4 x 11.5 cm.
For analysis of polar substances The organic sorbent cellulose is particularly suitable for the separation of hydrophilic substances by partition chromatography. EMD Millipore cellulose plates include classical TLC grade or HPTLC plates for demanding high-performance separations: TLC cellulose...
Thin-layer chromatography (TLC) plates for adsorption, partition, and ion-exchange techniques. Six media choices with glass, polyester, and aluminum backings. Silica-based adsorbent layers in Sigma-Aldrich TLC plates incorporate a polymeric binder; highly purified silica gel plates incorporate a...
Provides uniformly fine mist or spray, required for paper chromatographic determination Conveniently located vent permits instantaneous control of spray Borosilicate glass tube has permanently attached, molded phenolic screw cap (size No. 24) with polyvinyl liner which fits commercial narrow mouth...
For Thin Layer Chromatography
HPTLC plates deliver fast and quantitative analysis of complex samples for manual or automated use. EMD Millipore’s HPTLC silica plates work three times faster than conventional TLC plates – and they’re more sensitive. The particle sizes range in HPTLC is between 4-8µ, which...
RP modified plates serve two purposes: act as a pilot method for HPLC and allow to choose various solvent system for special separations. RP-modified silica layers from EMD Millipore are well suited for many separation challenges that unmodified silica cannot overcome. These layers use aqueous...
Aluminiumoxide plates are used to analyze basic and neutral compounds at different pH levels. Depending on the pH range in question, professionals can choose between two kinds of aluminum oxide plates. Under aqueous conditions, basic aluminum oxide plates are best for separating basic compounds,...
Clear glass sides allow unobstructed visual inspection of contents Tank is ground flat to match ground glass lid. Beveled inside and outside to remove any sharp edges. Holds two 20 x 20 cm plates or four 10 x 20 cm plates. Latching device holds the matching ground glass surfaces of the lid and tank...
Our NH2, CN and DIOL -modified silica sorbents are less polar then conventional silica phases, making them ideal for separating hydrophilic or charged substances. Our moderately polar cyano- and diol-modified silica plates can be used for both normal phase and reversed phase systems. An...
