WPI NanoLiter2020 nanolitre injector with touchscreen controller

Click2Contact

The NanoLiter2020 is a microinjector from WPI, designed to perform precision injections in the nanolitre range using a variety of glass micropipette sizes. This latest model connects directly to WPI’s SMARTouch controller, which can also be used with the company’s UMP3 pump, allowing the pumps to be controlled individually or synchronously. It also offers improved precision by in-depth plunger displacement validation.

Injections are performed with mineral oil back-filled glass micropipettes, and the sample is front filled. This approach minimises loss of any costly or scarce samples when a minute sample volume can be adequate. Precise control is offered over injection volumes (in the nanolitre to microlitre range) and injection rates, the company says.

The product can control up to two pumps simultaneously and is easily mounted on a micromanipulator or a stereotaxic frame. It features a simple-to-use touchscreen interface and graphical representation of volume status on the MICRO2T controller.
