Abstract
A peristaltic pump for pumping a fluid includes a flexible tube and a roller. The flexible tube has inner and outer tubular opposed walls. The inner wall defines a through passage to receive the fluid. The roller has an outer contact surface. The peristaltic pump is configured to compress the flexible tube with the contact surface of the roller to thereby force the fluid through the through passage. At least the contact surface of the roller is formed of borosilicate glass.
Claims16
A peristaltic pump for pumping a fluid, the peristaltic pump comprising:
- a flexible tube having inner and outer tubular opposed walls, the inner wall defining a through passage to receive the fluid;
- and
- at least one roller having an outer contact surface;
- wherein the peristaltic pump is configured to compress the flexible tube with the contact surface of the roller to thereby force the fluid through the through passage;
- and
- wherein at least the contact surface of the roller is formed of borosilicate glass, the peristaltic pump further comprising:
- a roller carrier;
- and
- a roller axle pin coupling the roller to the roller carrier;
- wherein the roller axle pin is formed of borosilicate glass and the roller axle pin is stationary with respect to the roller carrier and the roller is rotatable about the roller axle pin.
