High speed centrifuge

高速离心机是生物化学研究人员必不可少的设备。该仪器用于收获细胞，亚细胞分离和涉及蛋白质，酶和核酸纯化的几个步骤。如果没有这个仪器，我们的大部分实验是不可能进行的，因为我们的工作主要集中在蛋白质、酶和核酸的基本特性上。我们目前有两个工作离心机和一个瘫痪了25年的离心机，由七个不同的研究小组共享，服务于60多名科学家。现有离心机包括一台使用了2年的Beckman Avanti JE，一台使用了12年的Beckman Avanti J25I离心机和一台使用了25年以上的Beckman J2-21离心机。两个阿凡提离心机是唯一能够执行我们的研究人员需要的任务。由于我们部门对这类设备的需求很高，我们一直保持着旧的贝克曼离心机。不幸的是，老贝克曼J2-21不再能够超过6000 RPM，最近需要昂贵的维修。由于这些离心机通常工作长达20年，我们的资金请求应该在未来几年内为七个研究小组提供必不可少的共享设备。如果没有这种新的离心机，这些研究人员的研究计划的相当大的延迟将导致他们的研究的重大和昂贵的延迟。

A high speed centrifuge is an essential piece of equipment for researchers in biochemistry.  This instrument is used to harvest cells, sub cellular fractionation and for several of the steps involved in the purification of proteins, enzymes and nucleic acids.  It would be impossible to perform most of our experiments without this apparatus since the main focus of our work is on the fundamental properties of proteins, enzymes and nucleic acids.  We presently have two working centrifuges and a crippled 25 year old centrifuge that are shared by seven different research groups and serve over 60 scientists.  The available centrifuges include a 2 year old Beckman Avanti JE, 12 years old a Beckman Avanti J25I centrifuge and a Beckman J2-21 centrifuge that is over 25 years old.  The two Avanti centrifuges are the only ones capable of performing the tasks needed by our researchers.  We have maintained the older Beckman centrifuge due to the high demand for this type of equipment in our department.  Unfortunately the old Beckman J2-21 is no longer capable of exceeding 6,000 RPM and has recently needed expensive repairs.  Since these centrifuges usually perform for up to twenty years, our request for funding should provide seven research groups with an essential piece of shared equipment for several years to come.  Without this new centrifuge, considerable delays in the research programs of these researchers will result in significant and costly delays in their investigations.
