Replacement of a centrifugal vacuum concentrator

真空离心蒸发器是任何实验室在生物化学和分子生物学研究领域工作的重要组成部分。因此，在这些领域受过训练的高度合格的人员经常需要这种设备，这些人员是在蒙特卡罗大学生物科学学院附属的生物研究所（生物研究所）受训的。真空浓缩器包括离心机、溶剂捕集器和真空泵。我所的公用设备实验室目前有一个真空浓缩器，装有两台离心机，经过20年的大量使用，在过去的一年里迅速老化。它显示出严重腐蚀的迹象，真空出现问题，两个离心机中的一个出了故障。由于它的年龄，这是不可能修理的设备，因为零件不再可用。该仪器每天被在所有共同申请者的实验室工作的学生大量使用，也作为其他IRBV实验室的偶尔资源。因此，要求资金购买适应我们所有应用的大容量培养摇床，包括DNA操作和在酸和碱中稀释的样品蒸发。

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.
