- Hanging drop crystallization
- Sitting drop crystallization
- Sandwich drop crystallization
Features
- High purity of glass
- Siliconized, hydrophobic glass surface

- 18 mm glass diameter
- Circle
- 0.22 mm glass thickness is UV Compatible (>85% transmission)
Description
Siliconized glass cover slides allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution.
These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use Dow Corning Vacuum Grease (HR3-510) or Dow Corning 7 Release Compound (HR3-508) to seal cover slide to plate. Available in 12, 18 or 22 mm diameter circles and 22 mm diameter squares. Available in 0.22 mm or 0.96 mm glass thickness. The 0.96 mm thick slides are virtually unbreakable during crystallization handling.

描述
硅化玻璃盖玻片允许液滴悬浮在一个位置，该位置为蒸汽扩散与周围的水库溶液提供近乎最佳的条件。
这些硅化玻璃盖玻片为结晶实验提供一致、高质量的光洁度。疏水表面会产生一滴“很好地”并且不会在玻璃上变平。硅化表面可防止晶体粘附和沉淀到玻璃表面上。使用道康宁真空润滑脂 (HR3-510) 或道康宁 7 离型剂 (HR3-508) 将盖玻片密封到板上。提供 12、18 或 22 毫米直径的圆形和 22 毫米直径的方形。提供 0.22 毫米或 0.96 毫米玻璃厚度。 0.96 毫米厚的载玻片在结晶处理过程中几乎牢不可破。
