Centrifuges: Top Questions to Ask Before Buying

Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning. Laboratories use centrifuges to clarify suspensions, separate liquids, isolate suspended particles, perform density measurements and for many other applications.

Top 5 Questions You Should Ask When Buying a Centrifuge

1. What is the maximum g-force the centrifuge can generate?

2. How does the company’s centrifuge differ from other ones that can do the same speed and capacity?

3. What kind of warranty comes with the centrifuge; what does it cover?

4. If the company discontinues the product, for how many years do they provide accessories and parts for the centrifuge?

5. Ask about cost of the purchase— not just the price of the product being installed but the total cost of ownership, which includes price, service expectations, warranty, etc.
