Crystal Clear Quartz capillaries that are extremely thin walled (approximately 10 micron wall thickness). The length of the capillary has a well defined diameter, with one end having a funnel shape and the other end closed. Quartz capillaries have a wall thickness of 0.01 mm and an overall length of 80 mm +/-5 mm. Quartz capillaries are available in a wide range of outside diameters from 0.1 mm to 5.0 mm. They are designed to mount, hold, and store small molecule and biological macromolecular crystals for x-ray data collection. Capillaries can also be used for crystal density measurements and crystal growth experiments. The capillaries can be sealed tightly against moisture and gases using wax, epoxy, or other sealing materials.
In determining what glass or quartz capillary is right for you, please refer to the “Linear Absorption Coefficient µ cm-1” table. This table indicates the amount of radiation that is absorbed by the capillary during x-ray data collection.
For 0.1 mm to 2.5 mm capillaries the open end capillary tube base size is 3.0 +/- 0.2 mm OD x 0.2 +/- 0.15 mm Wall thickness. For 3.0 and 3.5 mm capillaries the open end capillary base size is about 4.4 mm OD x 0.25 mm Wall thickness. For 4.0 and 5.0 mm capillaries the open end capillary based size is about 6.0 x 0.25 mm.
The Diameter is measured about 30 to 40 mm from the closed end (measuring instrument: LaserMicrometer LS 7500) The tolerances are as follows.
晶莹剔透的石英毛细管，壁厚极薄（壁厚约 10 微米）。毛细管的长度具有明确定义的直径，一端为漏斗形，另一端封闭。石英毛细管的壁厚为 0.01 mm，总长度为 80 mm +/-5 mm。石英毛细管的外径范围很广，从 0.1 mm 到 5.0 mm。它们旨在安装、固定和存储小分子和生物大分子晶体，用于 X 射线数据收集。毛细管也可用于晶体密度测量和晶体生长实验。可以使用蜡、环氧树脂或其他密封材料将毛细管紧密密封以防潮气和气体。
在确定适合您的玻璃或石英毛细管时，请参阅“线性吸收系数 µ cm-1”表。该表显示了在 X 射线数据采集过程中被毛细管吸收的辐射量。
对于 0.1 mm 至 2.5 mm 毛细管，开口端毛细管底座尺寸为 3.0 +/- 0.2 mm OD x 0.2 +/- 0.15 mm 壁厚。对于 3.0 和 3.5 mm 毛细管，开口端毛细管底座尺寸约为 4.4 mm OD x 0.25 mm 壁厚。对于 4.0 和 5.0 mm 毛细管，基于开口端毛细管的尺寸约为 6.0 x 0.25 mm。
