    品名 Item: Fullerene Soot

    貨號 Catalog# MRST

    包裝規(guī)格 50g/瓶; 150g/瓶。

    Description:  As-produced carbon soot prepared by the Kraetschmer-Huffman arc process.  MER fullerene soot is guaranteed to yield over 7 wt% fullerenes when extracted with toluene.  Typical composition of the extract is 75% C60, 22% C70, 3% higher-order fullerenes.  The particle size of the soot is 0.02 to 10 microns.  Powder density is about 0.05 grams/cc.

     

    品名 Item: Refined Mixed Fullerenes    改進(jìn)的混合富勒烯

    貨號 Catalog# MRMF

    包裝規(guī)格  5g20g150g

    Description: Fullerene extracted from arc-produced carbon soot.  The fullerene mixture (also known as (“fullerite”) is a dark-brown amorphous powder that is soluble in toluene, benzene, carbon disulfide and other fullerene-friendly solvents.  Fullerene composition is approximately 75% C60, 22% C70 and 3% higher-order fullerenes (C76, C78, C84 and others).     Powder density is about 0.8 g/cc.

     

    品名 Item: Fullerene C60, 99+%

    貨號 Catalog# MR6LP

    包裝規(guī)格  5g20g150g

     

    Description:  Over 99% pure C60 produced by chromatography.  The product is a dark brown powder with powder densitiy of about 0.8 g/cc.  Impurities include C70 and C60 oxides.  The material may also contain up to 0.2% adsorbed solvent.

     

    品名 Item: Fullerene C60, 99.9%

    貨號 Catalog# MR6HP

    包裝規(guī)格  5g20g150g

     

    Description:  99.9% or higher C60 produced by chromatography and sublimed to remove traces of solvent and other contaminants.  The product is a black crystalline powder with powder density of about 0.8 g/cc.  Impurities are traces of C70 and C60 oxide.

     

    品名 Item: 95+% C70

    貨號 Catalog# MR7LP

    包裝規(guī)格  1g5g10g50g

    Description: C70 produced in the arc, then purified to over 95% by chromatography. The material is a dark brown powder with powder density of about 0.8 g/cc. Impurities include C60, higher order fullerenes and fullerene oxides. The product may contain up to 0.2% absorbed solvent.

     

    品名 Item: 99+% C70

    貨號 Catalog# MR7HP

    包裝規(guī)格  1g5g10g50g

     

    Description: 99% or higher purity C70 produced in the arc, purified by chromatography, then sublimed to remove traces of solvent and other contaminants. The product is a black crystalline powder with powder density of about 0.8 g/cc. Impurities are traces of higher fullerenes and C70 oxide.

     

    品名 Item: Higher-Order Fullerene Mixture

    貨號 Catalog# MRHF

    包裝規(guī)格  100mg 500mg

     

    Description: Mixture of higher-order fullerenes produced by chromatography. Typical composition is around 20% C76, 20% C78, 40% C84, with other higher-order fullerenes. A HPLC chromatogram is supplied with the material to indicate approximate distribution of fullerenes. Limited quantities are available.
