对于选购磁力搅拌器有疑惑的用户而言,本文将详尽提供如何购买磁力搅拌器,应该从哪方面衡量选择合适的磁力搅拌器?
首先,你需要知道单位需要什么。 在开始搜索一个合适的单位之前,请列出搅拌器将要做的常见的工作。 你会搅拌什么样的体积样品?是否有必要在搅拌的同时加热样品? 你将使用什么尺寸的船只? 将它全部写在您在购物时将要使用的摘要中。 列表可能看起来像这样:
样品量:500-1000ml
最适温度:185°F。
烧杯直径:4.25英寸
您的工作规模也需要考虑。 传统的磁力搅拌器一次加热并搅拌单个样品。 然而,目前存在可同时处理多个容器的单元。 如果你是在大量混合,这很可能是值得考虑收购一个多方位单元,如Scilogex MS-H-S10磁力搅拌器热板 。
在这一点上,你还可以决定某些功能是否会提有效,如果额外的成本是值得的。 数字读出比模拟控制更有意义吗? 是否需要温度传感器来监控一致的温度? 您将通过笔记本电脑或计算机记录数据吗? 所有这些选项可作为附加装置从大多数制造商获得或集成到磁性加热板搅拌器中。
还应考虑维护要求和保修。 如果您计划长时间握在同一单元上,您可能需要搜索具有强大保修和低使用成本的产品。 保修是非常标准的全面,但它是服务和维护的成本,这是你需要考虑一旦保修期满了。
预算
Cost is always a guiding factor when purchasing laboratory equipment. Generally speaking, budget is one of the first considerations before making a purchasing decision. However, I would caution against this way of thinking. If you've decided you need to buy a magnetic stirrer, it's even more important that you get a unit that will do whatever you need it to, no matter the price. For example, you may choose to buy one model over another because it costs less. But will it perform the duties you need? If not, was it worth the money, whatever you saved? A piece of equipment that does everything you need it to do and costs $200.00 more will provide a better value. Look this way. If you spend $300 on a magnetic stirrer and it only does half the job you need it to do, is the investment worth it?
That's why we recommend setting a budget after you've determined what you want. Buying anything based on price alone rarely yields the satisfaction and efficiency you expect
