10 mm Thin Wall Tube, Length 8", 400MHz

Wilmad-LabGlass, 513-5PP-8-5, 10 mm Thin Wall Precision NMR Sample Tube, Length 8", 400MHzFeatures:The precision Tube has 3 fold less paramagnetic contamination compared to the Economy tube and can be operated safely at temperatures up to 230 °C, and within a temperature step of 120 °C.The 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.Application Notes:3 mm Economy Material ASTM Type 1 Class A Borosilicate Glass Impact on shimming quality by paramagnetic impuritiesSmall (400 ppm Fe2O3) Rapid cooling/heating Yes, within 120 °C Max. working temperature 230 °C Sample volume reproducibility0.5% for SKU with "-PS"Averaged Sample Volume within Rf coil 646.1 µl/cmOuter Diameter 9.9935 ± 0.0065 mm Cut-off wavelength 320 nmCompatible with Small Volume Insert Yes except for SKU with "-PS"Recommended Application Experiments that require critical shimming quality: Note 1: Impact on shimming quality varies upon magnetic field strength. The economy tube is recommended for 1D low field experiments.Note 2: Sample volume reproducibility refers to the maximum volume fluctuation when filling different NMR tubes to the same sample height. This number correlates to the reproducibility of time-domain signal amplitude between different runs.Wilmad-LabGlass's NMR Precision Tubes are manufactured from borosilicate glass that meets the requirement of Type 1 Class A glass from ASTM E438. Each of the individual NMR tubes released into the market has been manufactured in a state-of-art facility in the United States and passed multiple NIST traceable gauge control and optical surface defect checks.Unit of MeasurePack of 5 pcs.
