Warsash Scientific  offer the N-380 series of linear actuators from Physik Instrumente (PI). The compact N-380/N-381 linear actuators are suitable drives and micro manipulators for biotechnology and nanotechnology applications with rapid accelerations, velocities of 10mm/s and forces up to 10 N to enable high-dynamics and throughput for automation tasks.

The N-380 linear actuators’ open-loop version is intended for high precision applications where the absolute position is not important or is controlled by an external loop (video, laser and quadcell.) The N-381 model is equipped with a high-resolution position sensor, allowing sub-micrometer repeatability in closed-loop operation.

The NEXACT PiezoWalk technology is an alternative to stepper-motors or DC servo-motors providing several advantages. Due to the direct linear drive, there is no loss of precision as a result of converting rotational to linear motion. The position is securely clamped when switched off. The drive does not need to be powered and does not heat up. The working principle allows high resolutions within one step. In open-loop operation, motions can be resolved to about one nanometer.

The N-380 series of linear actuators can be used in applications including cell manipulation, biohandling, micromanipulation, laser tuning, and for motion in strong magnetic fields.
