| Specific mail-in samples (for example air sensitive material) may require the use of additional glass or fused quartz capillary tubes. Any additional capillary must fit and be secured inside the supplied Kapton tube.

| 11-BM does '''not''' provide glass or quartz capillaries for mail-in experiments. Only Kapton tubes (with an inner diameter of 0.81 mm) are provided for the mail-in service.
| |
| | |
| To purchase tubes, domestic users are referred to the vendors below for glass ('special' or 'borosilicate') or quartz capillaries. Tubes with diameter of 0.5 mm or 0.7 mm are recommended. As purchased from both vendors, the tubes are pre-sealed on one end, and have a flared opening on the other end for easy powder loading.

| Glass and quartz are both stable over the temperature range available via the mail-in service. Glass adds a bit smaller background to the diffraction pattern and is easier to seal, but fused quartz tubes are stronger and more likely to survive shipping and handling.
| |
| | |
| Due to small variations glass or quartz tube sizes, the 0.7 mm diameter size can be a tight fit in 0.8 mm Kapton tubes, but usually work.
| |
| | |
| Smaller tubes (e.g 0.3 mm) may be useful to lower [https://wiki-ext.aps.anl.gov/ug11bm/index.php/X-ray_absorption_%26_fluorescence X-ray absorption],

| When returning samples loaded in glass capillaries, please leave a note in the package so we be sure to take extra care when handling.

| A section of Kapton, Glass and fused Quartz capillary tubes are available at 11-BM for on-site experiments. Check with staff to confirm, but the materials and dimensions shown below are typically on hand.

| | |
| Use quartz for high temperature work ( > 450 C). Glass adds a bit smaller background to the diffraction pattern and is easier to seal, but fused quartz tubes are stronger, more chemical resistant, and survive higher temperatures.
