Blister Pack Reagent Dispensing for High-Throughput Assays

The system divides the reagent dispensing function into separate, isolated units - individual blisters for each reagent. Each blister is a self-contained unit that prevents cross-contamination while enabling high-throughput processing of multiple reagents through parallel or sequential dispensing operations.

The blister pack serves as an intermediary device between reagent storage and the biological sample. It provides a controlled interface that allows precise dispensing of fixed volumes while preventing direct contact and potential cross-contamination between different reagent sources.

Each reagent is enclosed in its own sealed blister, creating physical separation that eliminates cross-contamination. The segmented design allows multiple reagents to be processed in high-throughput applications without harmful interactions between them.

The blister packs are designed as disposable single-use units. Each blister is sealed and intended for one-time dispensing, ensuring that reagents never come into contact with other reagents or contaminated surfaces, thereby preventing cross-contamination entirely.

The frangible seal is designed to break automatically when a specific force is applied by the actuator, providing self-regulating precision dispensing. The seal's mechanical design ensures it breaks at the correct moment and location, eliminating the need for complex control systems while maintaining high precision.

The frangible seal is engineered with specific mechanical properties that change at a critical threshold. When the actuator applies sufficient force, the seal's structural parameters change, causing it to break and release the reagent. This parameter-based control achieves precise dispensing with relatively simple actuation mechanisms.
