| "Delphi
Research lab was using chromic acid to treat
glassware stains. In 1995, the company
switched to a non-chromium based cleaner (NOCHROMIX®).
The
benefits that the company gained from this switch
include improved worker safety, lower disposal
costs, reduced environmental liability, and
improved employee morale."

USES
NOCHROMIX®
is a patented,
white crystaline, inorganic oxidizer packaged in
pre-measured, hermetically sealed pouches. When
mixed with sulfuric acid, it forms a clear, strong
cleaning solution which:
- Chemically cleans
glassware without leaving residue on the glass surface
(neither detergent film nor heavy metal
residue).
- Removes stubborn stains,
deposits and silicones from glassware.
- Rinses freely, reducing
rinsing time.
Ideal for
basic research, educational, biochemical, clinical
chemistry and trace analysis
laboratories.
Recommended
by the ASTM for certain glass cleaning
procedures
Suggested for use by the U.S.
EPA and "Standard Methods for the Examination of
Water and Waste
Water". |
ADVANTAGES
NOCHROMIX®
cleaning solution
offers many benefits to all chemical or biological
laboratories, but is especially useful where living
cells and enzymes or trace metal analysis are
involved. Chromium compounds are highly toxic to
cells and enzymes.
NOCHROMIX®
- Contains no metal ions; no
toxic, heavy metal residues to adsorb to glass.
- Assures true and
consistent test results.
| In
Contrast, Pyrex glass has significant retention of
chromic ion adsorption on the glass surface which
can cause possible interference with
precision measurements in biological enzymes and
other reactions.
Easier
Disposal | Unlike chromium, NOCHROMIX®
does not contain metals that
pollute the environment, simplifying disposal of spent
cleaning solution.
NOCHROMIX® contains no known
carcinogens. Dichromates can be carcinogenic, and
a serious toxic hazard when in contact with chlorides or
inorganic ions. |
