74511 Results for: "Silica Flour"

Supplier: Merck

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 alternative to PEI cellulose, amino-modified NH₂ plates provide weak basic ion exchange characteristics with special selectivity for charged compounds.

Supplier: MERCK PRODUCTION CHEMICALS

Selection of Merck's standardised and modified silica gels that are available in many granulations and supplied from one single source, dedicated to chromatography. Standardised silica gels are widely used in separation processes to purify valuable compounds in ton quantities. Modified silica on the other hand is used in separation problems, which cannot be adequately solved using unmodified silica.

Supplier: Merck

Highly robust plates with gypsum as binder, fully compliant with international pharmacopoeia (Ph. Eur. and USP).

Supplier: Merck

HPTLC plates, unmodified silica gel 60
This range of plates uses an optimised Merck silica gel 60 with a particle size of only 5 to 6 µm, which results in higher packing density and a smoother surface, therefore, reducing band diffusion. Less sample is required, 0,1 to 0,5 µl than for classic TLC.

Supplier: ISERA

A maximum of separation efficiency and perfect selectivity comply with highest demands.

Supplier: VWR Chemicals

VWR® powder pack reagents are designed to be used on laboratory and portable photometers with 16 mm cell capability. No calibration data is necessary. The pillows, individually sealed in aluminium foil packs, are unaffected by ambient conditions and contain pre-measured powder reagents for accuracy, convenience and great solubility.
