stem coaxial inserts for external referencing or locking order outside 7 nmr tube separately precision all glass construction makes the wilmad special stem coaxial insert the most versatile and reliable coaxial method available for nmr virtually eliminating sidebands general use is for external referencing external locking and determining magnetic susceptibility this system is also ideal for variable temperature studies because all the parts are made from pyrex® or equivalent glass outer tube must be ordered separately product number wgs-4bl wgs-5bl wgs-8bl wgs-10bl wgs-12bl wgs-15bl wgs-16bl for outer tube od mm 4 5 8 10 12 15 16 stem height mm 25 50 50 50 50 50 50 stem od mm 2 2 3 4 5 5 5 reference capacity 20 µl 60 µl 190 µl 410 µl 0.69 ml 0.69 ml 0.69 ml sample capacity 124 µl 530 µl 1,560 µl 2,600 µl 3.82 ml 6.16 ml 7.4 ml use the insert with wilmad tube no s 406-pp 427-pp 506-pp to 535-pp 513a-xpp 513-xpp 514a-xpp 515-xpp 16-7pp inner tube nmr outer tube extra caps 521-99010153-100 cap for this tube included the upper section of each insert fits snugly into the outer tube much like a syringe plunger fits its barrel the stem is held straight within 0.013mm order the outer tube separately cap for this tube 521-g r resonance report for a detailed explanation of the application of this and other microcells request resonance report nmr-008 you can also see this resonance report on wilmad s home page under products and services at www.wilmad-labglass.com 26 www.wilmad-labglass.com 28
