Miles Scientific Analtech Silica Gel RP18F (Octadecyl Bonded Reversed Phase, Fluorescent indicator) TLC Plates on Glass, 250 um, 20 x 20 cm, 25/Pk - P173011

Glass-backed Analytical TLC Plates

Miles Scientific Analtech Brand RP18F Thin Layer Chromatography (TLC) Plates on Glass (with Fluorescent indicator UV254) - Glass-Backed - 250µm Thickness - 20x20cm - Box of 25 Plates

Product Number: P173011

Weight: 11.10 LBS

• RP18 - Octadecyl Bonded Silica Gel Reversed Phase for HPTLC
• F - Fluorescent indicator UV254. (Can be added to any adsorbent.)

These reversed phase TLC plates have been manufactured to be greater than 50% and less than 100% silanized. Because of this they are hydrophobic, but wettable (unlike Product Numbers P164077 & P165077 which are 100% silanized). 

Reversed Phase Unibond™ Series HPTLC UNIPLATES

The availability of both normal phase and Reversed Phase HPTLC UNIPLATES™ completes HPTLC as a sensible, efficient and cost effective alternative technique for quantitative analysis. These Reversed Phase adsorbents share the features and benefits of silica gel HPTLC plates: high efficiency adsorbents, 150 μm layer thickness, and smooth surface for densitometry. In the High Performance format, Analtech offers several varieties of supports. A hydrocarbon impregnated layer, similar to the analytical RPS UNIPLATE, offers complete aqueous solvent compatibility. Three nonpolar bonded supports in the UNIBOND™ series are available: RP2, RP8, and RP18.

These fully silanized silica gels share complete compatibility with all organic solvents. However, due to the extreme hydrophobic nature of the RP18 adsorbent, aqueous wettability is limited to approximately 60% water in the mobile phase. Wettability is correspondingly higher with the slightly more polar shorter chain RP series plates.
