An ultracentrifuge and rotors to support multiple NSERC-funded programs

超速离心法是生物学研究中的一种标准技术，用于鉴定和纯化细胞内的细胞器、组件、生物膜和其他分子，使用各种不同的复杂方法。所有这些方法都使用超速离心机，使复杂的生物材料样本受到极高的离心力；离心力大约是重力的10万倍。这些样品被固定在转子中，这些转子被设计成容纳适当大小和配置的管。康科迪亚大学生物系的七个研究小组经常需要超速离心法。因此，该部门的单一超速离心机使用量很大；全年95%的工作日(和夜间)和50%的周末几乎不间断运行。为数不多的转子已有几十年的历史，并与其他部门共享。因此，生物系迫切需要第二台通用超速离心机和新的转子。

Ultracentrifugation is a standard technique in biological research used to identify and purify intracellular organelles, assemblies, biological membranes, and other molecules using a variety of different sophisticated methods. All of these methods use an ultracentrifuge to subject complex samples of biological material to extremely high centrifugal forces; on the order of 100,000 times the force of gravity. These samples are held in rotors which are designed to hold tubes of the proper size and configuration. Seven research groups in the Biology Department of Concordia University routinely require ultracentrifugation. Consequently, the single ultracentrifuge in the department is heavily used; running nearly continuously on 95% of weekdays (and nights) and 50% of weekends throughout the year. The few rotors are decades-old and shared with other departments. Therefore, there is an urgent need for a second common-use ultracentrifuge and new rotors in the Biology Department.
