样品前处理

各位实验室同仁，我是做药物代谢的，以前最害怕做样品处理，因为样品多振荡器只能一个或两个分开振，样品多了振的手都麻了，还有如果是液体体积较大，小振荡器还振不起来，不均匀，尤其是液液萃取时，液体稍多点根本振不好，还有复溶时加100或200uL复溶，振荡器也不能把干在较高试管壁上的药物溶下来；

前段时间朋友给我推荐了一个叫multi-tube vortexer(多管振荡器），刚开始不以为然，后来去他们实验室看了，哇塞，那个棒；可以同时振荡一批（上百个）样品，只要把样品放到试管架上上下一夹，1分钟或半分钟搞定，尤其是振荡器劲大，可以振荡几毫升的液体，复溶也很好；后来就给老板说了，买了一个。太好了，

真心推荐给各位同仁，要学会保护自己，听说这种振荡器在国外每个分析实验室都有，还是外国佬会享福呀。见附件图片

谢谢分享！！

再次给大家介绍个好东西，连续加样器，英文是repeat pippte,国内大多实验室用的加样器一次只能加一个样品，这中连续加样器有各种吸头，比如1mL(25uL）的吸头意味一次吸取1mL的液体，每按一下加样25uL,这样吸一次液体可以加样40个样品，对于做生物分析的实验室加内标可方便了；另外还有个优点，绝对比普通加样器一个个加样准确，均匀；

如果大家加体积大的液体的话，可以用瓶口分液器，每次瓶中放入1升的液体，调好每次喷出的液体量（比如500uL),按一次就打出500uL;又快又准确

我觉得实验室必须有好的实验工具，毕竟严重影响我们的效率和准确性呀，推荐给大家，希望能帮助到大家

谢谢各位的支持

希望能对实验室各位战友有帮助

详细的应用专业范围，介绍给大家

好像对细胞悬浮，质粒提取等生化专业，蛋白水解都挺实用的

The Multitube Vortexer is designed for mechanical and chemical cell lysis, mixing suspensions, and general sample agitation. This vortex mixer gives a distinctly different motion than shaking a sample. With vortexing, greater shearing forces are placed on materials in the bottom of a tube, thus promoting either disruption or solubility. The multi-tube vortex mixer is a tool to provide that extra degree of mixing, however it accommodates full racks of tubes or microwell plates as opposed to singe tubes. Consequently, this unit is useful for higher throughput mixing of samples.

The multi tube vortexer can be used for resuspending bacterial pellets, mixing reagents for alkaline lysis plasmid preps, mixing of components for bead-based assays, mixing of aqueous and organic solutions for extractions, mixing of solid phase supports and reactants, and any other process which requires a vortexing step. This mixer is sturdy yet quiet in operation.
