4 mm Thin Wall Quartz EPR Sample Tube
Quartz (CFQ) EPR Tubes – 4mm OD
EPR Tube Product numbers that include “PQ” belong to our Precision Tube Family. Those with “SQ” are our Economy brand tubes. 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.
GROUP SKU : WILMAD-4MM-THINWALL-QUARTZ-EPR-TUBES
- 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, especially in tubes of over 4 mm OD. In this case we recommend switching to Suprasil® EPR products which are made of synthetic material and suppress major impurity contents shown in Table 1 by the average of 2 orders of magnitude.
- Save Time Heat-Sealing EPR Samples! Heat-sealing quartz tubes is difficult enough so we’ve provided an easier way. By ordering our constricted tube you’ll seal EPR tubes more quickly, with less effort.
- Scientists rely on the expertise and artistic skills of Wilmad-LabGlass engineers and glass specialists to manufacture NMR and EPR consumables and laboratory glassware of the highest quality.
- Used daily in academia, healthcare and chemical, petroleum and other industrial applications, Wilmad offers 7000+ items as part of their standard catalog as well as custom fabrication for individual glassware, glass repair services and OEM glass parts.
