Source: Paolone, G., et al. Personalized Needles for Microinjections in the Rodent Brain. J. Vis. Exp. (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 The needle is withdrawn after a brief pause.

FAQs
Quartz Window components transmit ultraviolet radiation that ordinary glass may absorb, allowing more of the available light to reach the sample and detector. This difference is important when chemical analysis depends on ultraviolet-visible spectroscopy, because insufficient ultraviolet transmission could limit measurement of composition or reaction changes under controlled laboratory conditions.
Thermal stability helps a quartz window retain its optical and physical function during high-temperature experiments. The material can provide a transparent barrier while the reaction environment is heated, whereas ordinary glass may deform or fail. This property supports measurements and observations in experiments where temperature would otherwise compromise the optical component.
Chemical resistance helps the window remain compatible with many chemical environments while maintaining separation between the sample and surrounding instrument components. That isolation allows light to enter or leave a reaction vessel, spectroscopic cell, or enclosure without exposing the optical system directly to the sample, supporting controlled measurements of chemical behavior.
In ultraviolet-visible spectroscopy, the window forms part of the optical path through which measurement light reaches the sample and the resulting signal returns to the instrument. Its transmission across ultraviolet and visible radiation helps preserve the usable light required to analyze chemical composition or monitor changes during a reaction.
Photochemical reactions require radiation to reach the reacting material, so the optical component must transmit the relevant ultraviolet or visible light while keeping the sample contained. A quartz window provides that access and physical separation, enabling researchers to expose a reaction to controlled illumination and monitor its chemical progress with optical measurements.
Fluorescence measurements depend on light entering the sample and emitted radiation reaching the detection system. A quartz window supports this optical access across relevant ultraviolet and visible regions while maintaining sample isolation. As a result, it can be incorporated into spectroscopic cells or instrument enclosures used to observe fluorescence from chemical samples.
Experiments that combine elevated temperature with optical observation or measurement benefit most from these windows. Their thermal stability helps maintain a transparent interface when ordinary glass could deform or fail. This makes them relevant to reaction vessels, spectroscopic cells, and instrument enclosures used to analyze composition or monitor reactions under heated conditions.
