What is the diameter of these vials? I want to make sure they will fit in my digestion block

This product has a diameter of 30.3 mm (1.19\") and a height of 106 mm (4.17\")

Does the Ultimate Clean Cup come with Volume certification?

Yes, there is a statement of volume accuracy on the COA that comes with the cups. You can request a copy of the data by sending an email to info@envexp.com

Do the UCCs need to be rinsed with reagent water prior to use?

They do not need any pretreatment prior to use. They are ready to use when the plastic sealing wrap is opened.

What material are the cups made of?


What is the maximum temperature that the SC475 can be used at? Is it the same temperature for the UC475?

These digestion vessels are all molded from polypropylene. The maximum operating temperature for them is 130°C.

What is the difference between SC475 and UC475?

SC475 and UC475 are essentially the same cup with some minor cosmetic differences and one functional difference. They are both made of the same plastic resin and come with the same COA listing expected background metals levels. The UC475 cup is from a newer mold that has eliminated many of the old vent lines that were sometimes confused for graduation lines. The actual graduation lines are on two sides of the cup and have also been enhanced to be more legible. We have also added a marking patch on the side. The wall of the cup is slightly thicker to increase the robustness and resistance to more vigorous digestions processes. Most importantly, due to the new mold, the SC475 cup is being phased out of production and is projected to be discontinued by mid-May.

Are the watch glass or reflux caps you sell as clean as the Ultimate Clean Cups?

The watch glass (SC505) and reflux cap (SC506) are comparable in cleanliness to our regular cups (UC475). The lowered detection limits on our Ultimate Clean Cups are achieved by special packaging of the product immediately after molding. We do not have a similar method for packaging the watch glasses or reflux caps. Those products are small enough that they can effectively be acid washed prior to use to help achieve lower detection limits.

Do the graduations on the side meet \'Grade A\' glassware tolerances

Yes, they do. We test this product the same as the other 50-mL digestion vessels that we offer. They will come with a lot number that you can use to find the volume study data here - http://www.envexp.com/component/content/article/148?Itemid=109

I see iron contamination as up can have upto 24 ppb of iron contamination? Or is 25 ppb just the detection limit for the method used to certify these lots.

We guarantee every cup to have a level of less than 25 ppb for Fe. The cups may contain levels much less than that, but that is the lowest level for which we certify our Ultimate Clean Cups.

like to try your new cup..can you send a couple to try

Unfortunately, we do not send samples of this product. This product is packaged in a certain way that allows it to maintain the low background metals levels. Our packaging doesn’t allow for samples to be sent.

Do the ultimate clean cups, UCC000-50, come with caps.

Yes, the Ultimate Clean Cups come with the caps screwed on already to preserve the low-metals background.

could you tell me the exact dimensions of the cups ( diameter and height)? Thank you!

This product has a diameter of 30.3 mm (1.19\"), a height of 106 mm (4.17\"), and a total volume of 63 mL.

Do the filtermate filters fit these cups?

Yes, the FilterMates do fit the Ultimate Clean Cups.

In the cardboard box are all tubes in 1 large plastic bag, like SC475, or perhaps smaller bags each with some portion of tubes and caps? Thanks. I should\'ve probably emailed my sales rep. :-)

The Ultimate Clean Cup (UCC000-50) will come in a box of 150 cups which are packaged in 6 individually wrapped trays of 25 cups each.

Do you have a question?
