Q. If I have a pound of product and mix with distilled water what volume of liquid will I have to work with?

A.  With one pound of Sodium Polytungstate Powder you would have 1 – 1.5 pounds of volume.

Q. What are the best ways to assess when to recycle water-based solutions, and how to recycle them?

A.  When the material gets watery, heat it up slightly to evaporate off some excess water.  When too many minerals
are in it filter off some to clean them away.  If you need to change the density of the material add some distilled
water to it.

Q. In working with SP Liquid I used the filters suggested in the SDS sheets but the dried product now looks slightly darker. Is this discoloration normal?

A.  You are using the correct filters.  Once you have liquefied the powder material you should not dry it out.,
but keep it in liquid form.  Over time and use it will discolor and the density will change.  A drop or two of
hydrogen peroxide purchased from your local drugstore may help return the product to its original color.

Q. Does the Sodium Polytungstate information pertain to SPT-0?

A.  All data from the SP products are also valid for SPT-0.

Q. I bought Sodium Polytungstate Liquid awhile ago and the density is a bit lighter that it should be. How can I get the product to return to its proper density?

A.    There can be some fluctuation when a water based product sits on a shelf, even in a controlled atmosphere.
We recommend slightly heating the product to get the desired density.  In the future you may want to
purchase the Sodium Polytungstate Powder and mix your own.

Q. Is there any harm in putting this product in an ultrasonic bath?

A.  We have not heard of any harmful effects, as long as you do it under a ventilation hood and practice the
same safety measures as you normally would.

Q. What is the safest way to handle this product while working with it?

A.  These products are hazardous and should be used under a ventilation hood.  You should also wear an
appropriate mask, gloves, and try to limit exposure to skin and breathing.

Q. How do I decide which product is right for me, Chemical Based or Water Based?

A.  The right product is based on your personal preference.  To help you decide we usually suggest purchasing
one pound to test and see if you get the desired results for your project.

Q. What is the proper way to recycle chemical based products?

A.  Wash samples and all glassware by dissolving the remaining product in pure acetone.  This acetone-product
mixture is then stored in containers.  Recycle the product by adding water and separate the dissolved liquids.

Q: Is it common for the product to darken in color? Is there a way to make it colorless again?

A:  It is common for the material to darken over time.  A drop or two of hydrogen peroxide purchased from your local
drugstore may help return the product to its original color.
