What this tube is for

A 5 mm NMR tube made of fused quartz (silicon dioxide, SiO₂) instead of borosilicate glass. 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 for ¹¹B NMR and for studies with UV light.

Boron NMR. Borosilicate glass contains boron, so a normal NMR tube adds a broad boron signal from the glass to ¹¹B spectra. Deutero gives a boron content below 0.1 ppm for the quartz of these tubes, so the glass does not add that signal.

UV light. Quartz lets UV light through: Deutero gives a transmission of over 85 % above 265 nm. This makes the tube suited to photochemical studies, where the sample in the tube is irradiated with UV light.

Heat. Quartz expands much less with heat than borosilicate glass, which gives the tube a much higher thermal stability.

Your choices

Grade: 300 or 500 MHz. The grade tells you how straight and round the tube is. Choose the grade of your spectrometer, or a higher one. A higher grade spins more evenly and gives sharper lines; a lower grade on a high-field instrument can broaden them.

Length: 7 inches. This is the length of the glass tube. 7 inches (178 mm) is the standard NMR tube length.

Pack. Packs of 5 tubes, each tube with its cap.

The most common choice is qtz500-5-7: the 500 MHz grade.

Technical specifications

Item no.	Grade	OD (mm)	Concentricity / camber (µm)
qtz500-5-7	500 MHz	4.950 ± 0.015	5 / 13
qtz300-5-7	300 MHz	4.950 ± 0.030	7 / 25

Both tubes: fused quartz (silicon dioxide, SiO₂), boron below 0.1 ppm, UV transmission over 85 % above 265 nm, 0.38 mm wall, 7 in (178 mm). Packs of 5 tubes, caps included. Every Deutero tube is tested on Deutero’s in-house 500 MHz NMR spectrometer.
