The Model 720 emerged as a solution for mid-to-high volume processing where filtration speed and particle retention were critical. It bridges the gap between small-scale batch processors and massive industrial continuous centrifuges. Its longevity in the market is a testament to a design that prioritizes mechanical simplicity over unnecessary complexity, resulting in a lower total cost of ownership for operators.

The Model 720 typically utilizes a robust aluminum rotor with rubber cushion inserts. These inserts accommodate standard 100ml pear-shaped or cone-shaped centrifuge tubes. The design minimizes vibration even when the load is slightly unbalanced—a common issue when dealing with volatile samples.
