Several times since starting my tenure-track faculty position, I’ve had to purchase major pieces of scientific equipment. I define this as scientific equipment that costs greater than $5,000. For many of my colleagues in the U.S. this would not be a large amount of money, but it represents a significant portion of my yearly research grant, which means that I need to make a good decision about what I’m purchasing.
My first step in this process is to brainstorm a list of what I need the equipment to do (e.g. features, attachments, flexibility, etc.) and any physical limitations that have to be taken into account (e.g. Will it fit somewhere in the lab? Does it have particular power requirements?). Taking a few minutes up front to clearly define the minimum requirements that you have for the equipment saves a lot of time later, so don’t skip this step.
The next step is to gather information about the type of equipment that you are looking for. I do this by talking to colleagues and getting recommendations, thinking about any previous experiences that I have had with this kind of equipment, and browsing websites and catalogues. Once I’ve collected these data, I put them into a table so that I can compare the different models of equipment offered by different suppliers. Often one model will emerge as the front runner, and sometimes I can effectively rule out a particular piece of equipment by doing this comparison.
Only after I’ve identified the models that I’m interested in, do I contact scientific companies to ask for quotations. When I make a quotation request I include: i) the specific model that I’m interested in, ii) any accessories that are necessary for my research, and iii) information on the regular warranty that is offered and the pricing of an extended warranty. I send the requests for quotations out on the same day and time as a way to gage the responsiveness of the sales representatives as this information sometimes factors into my decision making process.
Many of my purchasing decisions come down to price, so it’s helpful to be comparing apples to apples instead of apples to oranges. I comparison shop when I buy my weekly groceries; why wouldn’t I do the same thing when it comes to buying scientific equipment?
