Source Data and Code for an Open-Source Microinjector

An open-source, footswitch-actuated microinjector for nano- or microliter volume injections can be assembled in less than 2 hours for under $130 USD. The device is self-contained, pressure controllable, and offers aspirate and discharge modes for in vivo procedures. The dataset, shared by Victor H. Dominguez under a CC-BY-4.0 license, contains the source data and code supporting this hardware design.

Use Cases

• Replicate the microinjector assembly based on the provided build instructions and component list.
• Analyze the performance data for dispense errors, which are reported to be around 15%.
• Modify the open-source design for specific experimental needs or to integrate with other lab equipment.

Strengths

• The design is documented as costing less than $130 USD and requiring less than 2 hours to assemble with ordinary tools.
• The device performance is quantified, with pulse-triggered discharges reliably delivering nanoliter volumes and a stated dispense error of around 15%.

Limitations

• The dataset is very small at 29.5 KB, indicating limited scope, likely containing only design files and minimal supporting data.
• Row count and column-level documentation are absent, requiring manual inspection after download to understand the data structure.
