WIL507-PP-7-5 - 5 mm Thin Wall Precision NMR Sample Tube 7" L, 300MHz/ PK5
General Description:
Wilmad-LabGlass’s NMR Precision Tubes are manufactured from borosilicate glass that meets the requirement of Type 1 Class A glass from ASTM E438. Precision Tube has 3 fold less paramagnetic contamination comparing to the Economy tube, and can be operated safely at temperature up to 230 ˚C, and within a temperature step of 120 ˚C. Precision tube is rated as hydrolytic class 1, which states that the inner surface is resistant to strong acid and base at ambient temperature. Wilmad-LabGlass is adopting a unique precision shrinking and grinding process to shape the inner surface with maximized filling factor (10% more than Economy tube), and a tight ID and OD tolerance as small as 0.0065 mm.
