Peristaltic pump (how it works)
The mechanism behind dosing pumps. A rotor compresses a hose, pushing the liquid precisely.
Detailed explanation
The peristaltic pump pushes liquid by compressing a hose with a roller rotor. Assays from 0.1 ml are possible.
Silicone hoses degrade: replace every 6-12 months. Norprene tubes last longer. Calibrate the flow rate periodically.
