描述

Same great Micro-Bridges, but manufactured from clarified polypropylene. These Micro-Bridges are resistant to most organic solvents, and are especially useful with crystallization experiments that involve detergents and other hydrophobic reagents. They resist drop-spreading typically observed when using reagents such as detergents, volatile organics such as iso-propanol and ethanol, and non-volatile organics such as MPD. These Micro-Bridges also resist acetone, dioxane, acetonitrile, 2,2,2-trifluoroethanol, and other aggressive organic solvents.

Approximate dimensions: Height: 12 mm Length: 14 mm Width: 7 mm

同样出色的微型桥接器，但由澄清的聚丙烯制成。这些微桥对大多数有机溶剂具有耐受性，尤其适用于涉及去污剂和其他疏水性试剂的结晶实验。当使用诸如去污剂、挥发性有机物（例如异丙醇和乙醇）以及非挥发性有机物（例如 MPD）等试剂时，它们通常会观察到液滴扩散。这些微桥还可以抵抗丙酮、二恶烷、乙腈、2,2,2-三氟乙醇和其他腐蚀性有机溶剂。

Quartz Capillaries

应用

X-ray data collection
Liquid-liquid diffusion crystallization
Gel acupuncture crystallization
X 射线数据采集
液-液扩散结晶
凝胶针刺结晶

特征

Thin walled – 10 micron
Quartz Glass 0620
薄壁 – 10 微米
石英玻璃 0620

描述

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。

直径从封闭端测量约 30 至 40 毫米（测量仪器：LaserMicrometer LS 7500）公差如下。

陶瓷切割石

描述

These small (25 mm x 25 mm x 0.65 mm) cutting stones are used to make clean cuts of glass and quartz capillaries. Use the edge of the stone to etch the capillary then gently snap the capillary in two. This is useful for cutting the tips off closed capillaries used for mounting single crystals for x-ray diffraction analysis or for cutting capillaries to the desired length.

Capillary Cutting Procedure

1. Gently place the capillary on a clean, flat surface.
2. Gently holding the stone at approximately 30° angle to the capillary tube, starting near one edge of the stone, proceeding in a single, smooth motion, draw the length of the non-serrated edge of the stone across the capillary one time . Apply just enough pressure to score the capillary, do not attempt to cut through the capillary.
3. Pull the capillary axially until it breaks. If it won’t break, the score was not deep enough. Repeat the above steps, pressing down with slightly more force while drawing the cleaving stone the capillary.
4. Once cut, inspect the end finish to ensure the cut quality meets the application requirements.

这些小的（25 毫米 x 25 毫米 x 0.65 毫米）切割石用于对玻璃和石英毛细管进行干净的切割。使用石头的边缘蚀刻毛细管，然后轻轻地将毛细管一分为二。这对于切割封闭毛细管的尖端非常有用，这些封闭毛细管用于安装单晶以进行 X 射线衍射分析或将毛细管切割成所需的长度。

毛细管切割程序

1. 轻轻地将毛细管放在干净、平坦的表面上。
2. 以与毛细管成约 30° 角的方式轻轻握住石头，从靠近石头的一个边缘开始，以单一、平滑的动作进行，将石头的非锯齿边缘的长度拉过毛细管一次。施加足够的压力来刻划毛细管，不要试图切穿毛细管。
3. 轴向拉动毛细管直至其断裂。如果它不会打破，那么分数还不够深。重复上述步骤，在将切割石拉入毛细管的同时稍微用力向下按压。
4. 切割后，检查端部光洁度，确保切割质量符合应用要求。
