The type of pump you choose for your fluid handling will largely depend on your laboratory application. In this article, we will compare the popular pump types.
You can find a range of pumps on the market today, and each microinjection pump is suited for its own applications. In this article, we will compare the volume ranges of a variety of pumps and consider the applications these pumps are best suited for.
This simple kit helps to dampen the pulsations of a peristaltic pump.
Microinjection uses either a metal needle or a glass micropipette to inject small liquid volumes. For example, genetic material may be inserted into a living cell, a drug introduced into an eye or brain, or fluid injected into a muscle. Typically, microinjection is performed under a microscope.
The Nanoliter injector is a micro-processor controlled injection system that uses direct piston displacement. The collet assembly (exploded view) is shown in the image below. The glass pipette fits into the white, plastic sleeve (spacer). When the collet is screwed in place securely, the black rubber washers are compressed and hold the glass firmly in place.
When it comes to setting up microinjection systems, the options appear endless. The pictures below give some broad suggestions on how you might set up your own system. Keep in mind that many parts are interchangeable depending on your needs or preferences.
WPI carries a wide variety of fluid handling tools utilizing three different technologies:
- peristaltic pumps
- syringe pumps
- pneumatic injectors
