Wilmad 328-PP-8 Precision 3 mm NMR Sample Tube, 500 MHz, 8 L (Pack of 5)"
Manufactured in a state-of-the-art iso 9001:2008 usa facility using a unique precision shrinking and grinding process to shape the inner surface with maximized filling factor
Inner surface is resistant to strong acid and base at ambient temperature
Can be operated safely at temperatures up to 230°c, and within a temperature step of 120°c
Rated as hydrolytic class 1
Ideal for experiments requiring critical shimming quality (high/ultrahigh field, non-spinning, multi-dimensional, multi-nuclei, dnp experiments and studies involving biological samples)
Wilmad is adopting a unique precision shrinking and grinding process to shape the inner surface and outer surface. This process brought a highly reproducible (within 5%) filling factor and 100% fit to the spinner turbine. Each of individual Wilmad NMR tubes released into the market has passed multiple NIST traceable gauge control and optical surface defect checks. Four ultrasonic washing cycles guarantee each Wilmad tube is free of any trace of contamination for NMR spectroscopy. Wilmad Precision NMR Tubes are manufactured from ASTM E438 Type 1 Class A glass, which has 3 fold less paramagnetic contamination comparing to the Economy tube glass, and can be operated safely at temperature up to 230 ËšC, and within a temperature step of 120 ËšC. Precision tube is rated as hydrolytic class 1, which states that the inner surface is resistant to strong acid and base at ambient temperature.
