１

We Kanto Chemical are creating new reagents lineup. Primepure is the brand name of highly-pure-

reagent lineup. Primepure series are Highest quality reagent within commercially available. Reduced

metal (more than 20 elements) and organic impurities.

「Primepure」 is products lineup with guaranteed

metal impurity content ppb Level.

Features

The Highest purity Primepure products are refined with Kanto's special treatment. The quantity of each element

is at the ppb level at most, which offers the most superior product in purity on the market.

More than 30 Items guaranteed- Guaranteed Metallic Impurity (over 20 elements) under ppb level.

- Reduce Organic impurities and Non-volatile components

- Reduce 4-Hydroxy-4-methyl-2-pentanone (Acetone- Dimer) in Acetone.

Custom madeWe can add parameter not listed on current Spec. Please contact us for a quote on your special

requirements. Like Special package size, add items, unique specifications etc.
