MP-1 & MP-2 Peristaltic Pumps

Spectrum Chromatography manufactures 2 different pumping systems for use in low-pressure liquid chromatography. These pumps also find frequent use as general-purpose laboratory pumps. To allow for maximum flexibility, the pump drives and pump heads are sold separately.

Peristaltic pumps offer several advantages over other type of laboratory pumps. The most significant advantage is that the only wetted material is the tubing you select. This permits easily determination of the chemical compatibility of the pump and replacing the tubing eliminates any possibility of carry-over.

The 2 pump drives offered by Spectrum are the MP-1 and MP-2 drives. These each use the same pump heads but have different operating features. Each drive can accept up to 3 pump heads and also has remote control capabilities which allow them to be stopped remotely (e.g. by a CF-1 fraction collector at the end of a run).

Two different styles of pump heads are available. The most common pump head is the Fast-Load pump head. This pump head accepts any flexible tubing with a wall thickness of 1/16" (1.6 mm) and an outer diameter of 7/16" (11.1 mm) or less. The tubing can be loaded into this pump head without removing the pump head from the pump.

The second style of pump head is the standard pump head. The standard pump heads each accept only a single size of tubing. To load or unload the tubing from the pump head, the pump head must first be removed from the pump.
