Replacement of a centrifugal vacuum concentrator

真空离心式蒸发器是任何从事生物化学和分子生物学研究领域的实验室的重要组成部分。因此，蒙特利尔大学生物科学研究所(IRBV)在这些领域接受过培训的高素质人员经常需要这种设备。一种真空浓缩器，包括离心机、溶剂捕集器和真空泵。我们研究所的通用设备实验室目前有一个装有两台离心机的真空浓缩器，在大量使用20年后，这两台离心机在过去一年里迅速衰败。它显示出严重腐蚀的迹象，真空问题，以及两台离心机中的一台出现故障。由于年代久远，这台设备不可能再修理了，因为已经没有零件可用了。在所有合作申请人的实验室工作的学生每天都会大量使用该仪器，也偶尔为其他IRBV实验室提供资源。因此，需要资金购买一台大容量孵化器-摇床，以适应我们的所有应用，包括DNA操作和在酸和碱中稀释的样品的蒸发。

A vacuum centrifugal evaporator is a vital component of any laboratory working in areas of biochemistry and molecular biology research. Thus, highly qualified personnel trained in these areas at the Institut de recherche en biologie végétale (IRBV, affiliated with the Département de sciences biologiques of Université de Montréal) frequently require this equipment. A vacuum concentrator comprises a centrifuge, a solvent trap and a vacuum pump. The common equipment laboratory of our Institute currently has a vacuum concentrator fitted with two centrifuges that has decayed rapidly over the past year after 20 years of heavy use. It shows signs of advanced corrosion, problems with vacuum and one of its two centrifuges is out of order. Due to its age, it is impossible to repair this equipment because parts are no longer available. This instrument is heavily used on a daily basis by students working in the laboratories of all the coapplicants and also serves as an occasional resource for other IRBV laboratories. Funds are therefore requested to purchase a large capacity incubator-shaker adapted to accommodate all our applications, including DNA manipulation and evaporation of samples diluted in acids and bases.
