At Biochip 2022 we are introducing a new design of a magnetic shape memory alloy pump prototype for volume flows in a range up to 1 ml/min. All msm®‑pump types consist of a replaceable pump head and a fixed magnetic shape memory alloy drive unit, which forms a travelling cavity on the magnetic shape memory alloy stick by a rotating magnet (see below).
Two msm-pump variants were developed, a stand-alone pump and a biochip-compatible prototype. In the above picture, a msm-130E prototype is shown as stand-alone pump and a msm-130C prototype with the fixed pump part for delivering liquids on disposable biochips. Using this technology applications of msm-pumps can be found in bio-, chip and medical technology, where a disposable pump component is mandatory.
Fields of application for msm-pumps
- Biochip technology
- Lab-on-Chip / Organ-on-chip
