描述

In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.^1-3

Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.

在透析方法中，有问题的样品通过半透膜与“沉淀剂”分离，半透膜允许小试剂分子通过，但阻止生物大分子穿过膜。1-3

透析按钮由聚苯乙烯注塑成型，大小与小按钮相当。将样品放置在该腔室中，以便在按钮顶部形成一个轻微的液体圆顶。透析膜放置在按钮/样品的顶部，并用 O 形环固定到位。 O 形环由透析按钮中的凹槽固定到位。透析按钮配有 O 形圈。 5 µl 至 100 µl 大小的透析按钮的总高度约为 6 mm，外径约为 10 mm，未安装 O 形圈，直径约为 12 mm，安装了 O 形圈。 200 µl 和 350 µl 大小的透析按钮总高度约为 8 mm，外径约为 15 mm，不带 O 形圈，直径约为 17 mm，带 O 形圈。每个透析按钮包都包括一个塑料高尔夫球 T 形涂抹器，以帮助将透析膜应用到按钮上并使用随附的 O 形圈固定。

描述

Micro-Bridges are small devices in the shape of a bridge that are designed to carry out sitting drop vapor diffusion crystallization when placed in a VDX™ Plate or Linbro® Plate. A single Micro-Bridge fits neatly into the reservoir of a standard 24 well VDX Plate for a sitting drop crystallization experiment. Once placed inside the wells, Micro-Bridges are stable and there is no need to stick them to the wells with grease or adhesive. It is therefore possible to transfer them to other wells during or after a crystallization experiment.

Why sitting drop? Placing the droplet in the indentation greatly reduces the risk of losing the protein by accident. Crystallization can be carried out in the presence of detergents and organic solvents which are compatible with polystyrene (such as MPD, iso-propanol, and ethanol). The protein drop is less affected by condensation problems. Soaking and seeding experiments can be carried out easily. Crystals can be transported more securely. Larger drop volumes can be used. Micro-Bridges have a concave indentation in the top surface of the bridge which holds the sample droplet during a crystallization experiment and prevents the droplet from spreading over a large area. Made from polystyrene, these parts are highly transparent and suitable for most crystallizations. The surface of the indentation is highly polished to facilitate the visual inspection of the drops under a microscope. The maximum drop volume for the Micro-Bridge is 35 µl. Reservoirs can be sealed with plain cover slides and vacuum grease or clear sealing tape.

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

微桥是桥形的小型设备，设计用于在放置在 VDX™ 板或 Linbro® 板中时进行坐滴蒸汽扩散结晶。单个 Micro-Bridge 可巧妙地装入标准 24 孔 VDX 板的储液器中，用于坐滴结晶实验。一旦放置在孔内，Micro-Bridges 就很稳定，无需用油脂或粘合剂将它们粘在孔上。因此，可以在结晶实验期间或之后将它们转移到其他孔中。

为什么要坐下来？将液滴放入压痕中可大大降低意外丢失蛋白质的风险。可以在与聚苯乙烯相容的去污剂和有机溶剂（如 MPD、异丙醇和乙醇）存在下进行结晶。蛋白质下降受冷凝问题的影响较小。可以轻松进行浸泡和播种实验。水晶可以更安全地运输。可以使用更大的液滴体积。微桥在桥的顶部表面有一个凹形压痕，用于在结晶实验期间固定样品液滴并防止液滴在大面积上扩散。这些部件由聚苯乙烯制成，高度透明，适用于大多数结晶。压痕表面经过高度抛光，便于在显微镜下目视检查液滴。 Micro-Bridge 的最大滴体积为 35 µl。可以使用普通盖玻片和真空润滑脂或透明密封胶带密封储液罐。

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.

应用

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。

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。
