The 5 mm is the outer diameter of the tube (4.95 mm), the size that most NMR probes take. The length, 7 inches, is 178 mm. Deutero makes it as a 600 MHz precision tube whose inner diameter hardly varies: 4.166 ± 0.004 mm. So the volume per millimetre of filling height stays the same from tube to tube, which Deutero describes as suitable for quantitative measurements.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe same volume in every tube.\u003c\/strong\u003e Worked out from Deutero’s figures: the tube holds about 13.6 µL per millimetre of filling height, and the ± 0.004 mm tolerance on the inner diameter changes this by no more than about ± 0.2 %.\u003c\/p\u003e\n\u003cp\u003eDeutero also describes the tube as suited to high-resolution NMR, with good reproducibility from sample to sample, and states that its thinner wall (0.40 mm) gives a higher signal sensitivity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-bottom: 28px;\"\u003e\n\u003cdiv style=\"background: #002147; padding: 10px 20px; margin-bottom: 0;\"\u003e\u003ch3 style=\"margin: 0; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 0.70em; font-weight: 700; letter-spacing: 0.12em; text-transform: uppercase; color: #fff;\"\u003eYour choices\u003c\/h3\u003e\u003c\/div\u003e\n\u003cdiv style=\"padding: 16px 20px; border: 1px solid #e4e8f0; border-top: none; font-family: Georgia, 'Times New Roman', serif; font-size: 0.95em; line-height: 1.65; color: #333;\"\u003e\n\u003cp\u003e\u003cstrong\u003eOne item: deuquant-5-7.\u003c\/strong\u003e The 600 MHz grade, 7 inches (178 mm) long, in packs of 5, each tube with its cap.\u003c\/p\u003e\n\u003cp\u003eFor routine spectra, the cheaper \u003ca href=\"\/products\/5-mm-economy-nmr-tubes-box-of-100\"\u003eeconomy tubes\u003c\/a\u003e are enough; for other grades, see the \u003ca href=\"\/products\/5-mm-precision-nmr-tubes-boro-5-1-glass-300-800-mhz\"\u003eprecision tubes\u003c\/a\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv style=\"margin-bottom: 28px;\"\u003e\n\u003cdiv style=\"background: #002147; padding: 10px 20px; margin-bottom: 0;\"\u003e\u003ch3 style=\"margin: 0; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 0.70em; font-weight: 700; letter-spacing: 0.12em; text-transform: uppercase; color: #fff;\"\u003eTechnical specifications\u003c\/h3\u003e\u003c\/div\u003e\n\u003ctable style=\"width: 100%; table-layout: auto; border-collapse: collapse; font-size: 0.95em; border: 1px solid #e4e8f0; border-top: none; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif;\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth style=\"padding: 9px 8px; text-align: left; font-weight: 600; color: #002147; background: #f7f8fb; border-bottom: 1px solid #e4e8f0;\"\u003eItem no.\u003c\/th\u003e\n\u003cth style=\"padding: 9px 8px; text-align: left; font-weight: 600; color: #002147; background: #f7f8fb; border-bottom: 1px solid #e4e8f0;\"\u003eOD (mm)\u003c\/th\u003e\n\u003cth style=\"padding: 9px 8px; text-align: left; font-weight: 600; color: #002147; background: #f7f8fb; border-bottom: 1px solid #e4e8f0;\"\u003eID (mm)\u003c\/th\u003e\n\u003cth style=\"padding: 9px 8px; text-align: left; font-weight: 600; color: #002147; background: #f7f8fb; border-bottom: 1px solid #e4e8f0;\"\u003eConcen­tricity \/ camber (µm)\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr style=\"background: #eef5fb;\"\u003e\n\u003ctd style=\"padding: 9px 8px; border-bottom: 1px solid #e4e8f0; color: #002147; font-weight: 600;\"\u003e\u003cspan style=\"white-space: nowrap;\"\u003edeuquant-5-7\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 8px; border-bottom: 1px solid #e4e8f0; color: #333;\"\u003e4.966 ± 0.004\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 8px; border-bottom: 1px solid #e4e8f0; color: #333;\"\u003e4.166 ± 0.004\u003c\/td\u003e\n\u003ctd style=\"padding: 9px 8px; border-bottom: 1px solid #e4e8f0; color: #333;\"\u003e4 \/ 4\u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv style=\"padding: 12px 20px; border: 1px solid #e4e8f0; border-top: none; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 0.9em; color: #333;\"\u003eWall 0.40 mm.
