50mL Digestion Vessel, Flat Bottom, Graduated, w. BLUE Cap, PP-CO, 500/Pkg [50-8001]

1/29/2018 – The picture shows the calibration markings on the tubes, but the resolution is not sufficient to see each level. It appears that 35 ml and 45 ml are missing. Which levels are not marked on the vessels?

Response From Texas Scientific Products: Yes, you are correct. 35 and 45 mL marks are missed on these DIGESTION tubes used in a Hot Block. The 50mL and 25 mL Volume Graduation marks are Class A certified. The digestion tube is graduated every 5 mL up to 30 mL and then every 10 mL from 30 to 50 mL.

If you need to use 35 and 45 mL marks - we offer the following "free standing", skirted graduated tubes:

1. https://cdn.nexternal.com/tsp/images/50-62559_300x300.jpg - graduated every 5 mL;

2. https://www.txscientific.com/50ml-polypropylene-freestanding-tubes-1ml-graduation--case-of-300-50-6011-p1351.aspx - graduated every 1.0 mL
