(2018).This video demonstrates a rodent brain microneedle injection using a quartz microneedle with holes. The microneedle is attached to a syringe and micropump to control the delivery rate. The needle with the injection solution is inserted into the brain with the delivery speed set at low. Once positioned, the delivery speed is increased. The needle is withdrawn after a brief pause.

This is most routinely achieved in the laboratory by the use of vacuum pumps. In addition to working at low pressures, vacuum pumps can also be used to enable rapid changing of the atmospheres in a reactor or flask by evacuation and backfilling.

FAQs
The holding force comes from a pressure difference rather than a mechanical grip. Vacuum ports or channels reduce pressure beneath the workpiece, while atmospheric pressure remains above it and presses the part toward the chuck. The resulting contact can secure a substrate while leaving its active surface unobstructed for processing or inspection.
Quartz provides a flat, chemically resistant surface suited to environments involving heat or aggressive chemicals. Its dimensional stability also supports consistent positioning and contact during precision work. These characteristics help limit contamination concerns and maintain repeatable conditions when the chuck is used for wafer handling, coating, laser processing, or metrology.
The arrangement of vacuum ports or channels influences how evenly the workpiece contacts the chuck. A suitable design can support uniform contact across the substrate and help maintain alignment during processing. In engineering systems, this contributes to more consistent positioning and can improve repeatability when parts must remain stable for inspection or fabrication.
A vacuum chuck secures the workpiece without placing clamps across its surface. This reduces physical obstruction during operations that require access for processing, inspection, or measurement and avoids potential damage associated with direct mechanical clamping. The approach is especially relevant when unobstructed surfaces, low contamination, and precise alignment are important.
A typical workflow places the substrate or component on the chuck’s flat quartz surface, aligns it with the intended processing position, and applies vacuum through the ports or channels. The resulting pressure differential holds the workpiece during the operation. After processing or inspection, releasing the vacuum allows the part to be removed without undoing mechanical clamps.
This approach is useful in wafer handling, photolithography, coating, laser processing, and metrology. These applications can require stable positioning, surface access, low contamination, dimensional stability, or resistance to heat and aggressive chemicals. The chuck’s design supports those requirements by combining unobstructed workpiece access with repeatable contact during manufacturing or inspection.
Integration can improve alignment, uniform contact, and process repeatability. Those outcomes matter when a substrate must remain consistently positioned across manufacturing, inspection, or processing steps. In laboratory and industrial systems, the quartz surface and vacuum workholding arrangement can support controlled handling while reducing reliance on fixtures that obstruct or contact the active part.
