Wilmad-LabGlass 705-PQ-6.25 3 mm Thin Wall Quartz EPR Tube, 6.25"

Wilmad-LabGlass, 705-PQ-6.25, 3 mm Thin Wall Precision Quartz EPR Sample Tube, 6.25"

Features:

• Precision brand EPR tubes hold 10-15 times tighter tolerance on the inner diameter, and >5 times smaller camber and concentricity over Economy Brand tube.
• Precision tubes are recommended for cw-experiments that require a constant filling factor or reproducibility on sample volume in the cavity.
• Clear Fused Quartz (CFQ) is purified from naturally occurring quartz so the existence of certain material radicals from mining is inevitable.
• Due to technological advancements the sensitivity of EPR has gradually increased.
• The direct result is that certain high Q cavities will pick up the signal from these impurities.
