Wilmad-LabGlass™ SP Scienceware™ 10mm O.D. Thin Walled Quartz NMR Tube
Wilmad Precision NMR Quartz Tubes have an extremely low thermal expansion rate and high tensile strength, which is 14 times more robust during the cooling/heating process than Type 1 Class A glass tubes
Brand: Wilmad-LabGlass™ 66407-1095
Allerta:
Caps are not recommended for use with samples dissolved in chloroform-d or acetone-d6
Descrizione
- Naturally occurring quartz maintains an over 85% transmission rate (10 mm thickness, with consideration of reflection loss) above 265nm that makes quartz tubes preferable in photochemistry studies
- Half the dielectric constant of Borosilicate Glass helps improve the quality factor
- Low Boron density at or below 0.1 ppm guarantees a clean background in Boron-11 NMR studies
- Tight I.D. and O.D. tolerance as small as 0.0065mm accommodates Wilmad inserts
- To maximize SNR, Precision NMR Quartz Tubes have minimal paramagnetic impurities that would impact shimming
- Inner surface is resistant to strong acid and base at ambient temperature
- 100% inspection with multiple NIST traceable gauges and optical surface defect check
