NMR Tubes 3 mm to 30 mm OD Precision NMR Sample Tubes

Wilmad’s NMR Precision Tubes are manufactured from borosilicate glass that meets the requirements of Type 1 Class A glass from ASTM E438. This type of glass is known in industry as Pyrex® glass. Pyrex® glass is composed of around 80% of SiO2 and 20% of B2O3, Na2O, Al2O3. Pyrex® glass is rated as hydrolytic class 1, which states that this type of glass is resistant to strong acid and base at ambient temperature or less. Each tube comes with a disposable cap.
Pyrex® glass can only be operated safely at temperatures up to 230 °C. Sudden temperature change should be controlled within 120 °C to avoid structure failure. Please refer to Page 54 for a complete list of tips to avoid tube breakage.
