Frequently Asked Questions
Your online catalog notes a
material's purity by the notations 3N, 4N, 4N5.
What do these notations mean?
We use the symbol
"N" to avoid confusion when referring to
high purities. Thus 2N indicates a purity of
99%, 2N5=99.5%, 5N8=99.9998%, 6N=99.9999% and so
on. The purities of rare earth products
are based on purities relative to other rare earths
only. Unavoidable contamination from reducing
agents or crucible materials, which may account for several
percentage points, are not included.
My son is doing a science
project for the local science fair. Can I
purchase materials from you?
As much as we'd like to help
your son with his science project we are restricted
from selling to individuals. Because we sell
materials which are hazardous we must verify that our
sales are made to established companies. Before
we can sell to any company, even if the purchase will
be made using a credit card, we must receive and
verify a bank reference and three relevant trade
references.
I have a requirement for
three metric tons of various materials; can you help
me with my requirement?
We specialize in supplying
small quantities of materials for research.
While we can supply kilograms of most materials we
cannot supply tons.
I need a good replacement for
organic cleaning solutions like trichloroethylene.
Would DeContam® be a good choice?
Yes, DeContam® would be a great replacement. DeContam® is water based and non-hazardous. For
more detailed information you can review our technical
data sheet - DeContam®.
I need a fine nickel powder. Your
online catalog shows that you stock two sizes, a -100
mesh and a -325 mesh. Can you explain the concept of
‘mesh’ sizes to me?
The term mesh refers to a screen with a certain
mesh or hole size that the powder passed through. For
a more detailed explanation you can refer to our mesh
technical data sheet - Understanding
Mesh Sizes.
