Wilmad Precision NMR Quartz Tubes

 Wilmad Precision NMR Quartz Tubes(5mm, 10mm)


Wilmad - LabGlass 는 80년의 역사를 가진, NMR Tube를 처음 제조하고 발명한 회사입니다. 
Frequency(MHz Rating)의 기준을 정격한 미국 브랜드로, 튜브의 직경오차가 작아 정밀성이 매우 뛰어납니다.

(주)비케이인스트루먼트는 미국 Wilmad- LabGlass사의 공식대리점으로 보다 합리적인 가격에 다양한 제품을 취급하고 있습니다.

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.

• 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 Pyrex® 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
• Manufactured in a state-of-the-art ISO 9001:2015 USA facility using a unique precision shrinking and grinding process to shape the inner surface with maximized filling factor
• Ideal for variable temperature experiments that have a temperature step over 120˚C as well as experiments at temperatures up to 1300˚C
• Inner surface is resistant to strong acid and base at ambient temperature
• 100% inspection with multiple NIST traceable gauges and optical surface defect checks
• Includes disposable cap

Note: Caps are not recommended for use with samples dissolved in chloroform-d or acetone-d₆.
