Wilmad 10MM NMR QUARTZ SAMPLE TUBE 8"LONG (5 PCS/PK)

Quartz NMR Tubes

Advantages of Quartz:

• Extremely low thermal expansion rate and high tensile strength. This feature makes quartz tubes 14 times more robust during cooling/heating process than corresponding Precision glass tubes.

• Naturally occurring quartz maintains over 85% transmission rate (10 mm thickness, with consideration of reflection loss) above 265 nm1.2, which makes quartz tubes preferable in photochemistry studies.

• Possesses a low Boron density as below 0.1 ppm, which guarantees a clean background in Boron-11 NMR studies.

• 2 times less dielectric constant than Pyrex® glass which helps improve the quality factor.Not recommended for EPR studies.
