If you have a lab, you will need to purchase equipment for it at some point. You can buy used equipment to save money too. Just make sure you buy said equipment in the following ways.
Look at Real Images
Suppliers that offer used lab equipment will usually provide real images of their supplies because they know buyers will want to see exactly what they're getting. You just need to go through these images patiently to get a clear picture of the condition you can expect when the lab equipment shows up at your own lab.
