The 2-stop Pharmaprene Purple-White Pump Tubing – PT-2290PH, manufactured by Pharmaprene, available in 12/pkg.
2-Stop and 3-Stop Pharmaprene tubing refers to a type of flexible tubing primarily for peritaltic pumps. In this case, the stops are color-coded markers that indicate the precise section of tubing that should be compressed by the pump rollers. The stops allow for precise fluid transfer and prevent the tubing from slipping within the pump head. As such, a 2-stop tubing has two color markers, while 3-stop tubing has three that often designate different fluid transfer volumes or separate different sample segments within a single tube.
Key Characteristics for 2-Stop and 3-Stop Pharmaprene Tubing
Function: The color-coded stops help to accurately position the tubing within the pump rollers, ensuring consistent fluid transfer and preventing damage to the tubing by precisely defining the compression area.
Material: Pharmaprene is a type of elastomer known for its excellent chemical resistance. In addition, its flexibility and biocompatibility make it suitable for use with various liquids in laboratory and medical applications.
Applications for 2-Stop and 3-Stop Pharmaprene Tubing
There are many applications for the 2-stop and 3-stop Pharmaprene tubing including two of the most common:
- Peristaltic pumps: Most commonly used in peristaltic pumps for precise fluid transfer in applications like liquid chromatography, cell culture, chemical analysis, and medical fluid delivery systems.
- Sample preparation: It is possible to do separate samples within a single tube by utilizing the multiple stop sections.
How to Distinguish between 2-Stop and 3-Stop Tubing
Distinguishing between the 2-stop and 3-stop tubing is simple. In fact, it is as easy as counting the number of stops on the tubing.
2-Stop: Typically used for standard fluid transfer with a single compression zone. Two color stops make it easy to use the tubing because they indicate the span of the compression zone directly on the tubing itself.
3-Stop: As the name indicates, this tubing allows for more complex fluid handling. For example, the 3-stop tubing can handle the transfer of multiple samples or create precise fluid volumes thanks to three color-coded compression zones.
