Functional Principle
The process of contact printing relies on factors like target surface wettability, impacting liquid volume and process success.
As the dispensing tip approaches the substrate, the needle establishes contact, enabling conductive adhesive engagement. After reaching the optimal dispensing distance and a brief pause, the needle withdraws, leaving microdroplets on the surface due to adhesive forces and surface tension. This precise contact printing technology showcases the synergy between pin-based mechanics, liquid properties, and surface interactions.
Various Available Pin Types
Capillary pins feature tapered ends, leveraging surface tension and adhesive forces for controlled liquid transfer. Their significant advantage lies in enabling several hundred depositions with just one uptake step. In contrast, blunt-end pins possess flat terminations, excelling in precise, direct contact dispensing. Capillaries offer superior precision for small volumes, making them ideal for high-throughput applications. Blunt-end pins ensure consistent and direct liquid deposition. Both pin types contribute to the versatility required for diverse microdispensing tasks.
Different Volumes
Pin sizes act as conductors of transfer volumes, harmonizing with liquid surface tension and surface wetting intricacies. Explore our contact spotting technology, offering diameters ranging from 80 to 500 Āµm. This spectrum accommodates precise deposition of 0.5 to 30 nanoliter sample aliquots.
Diverse Layouts of Pin Heads
We understand that every research project is unique, and that's why we offer a range of pin-head layouts tailored to your specific requirements. Our standard pin head comes with a 6 x 6 configuration, with a 4.5 mm distance, ideal for working with a 384-well plate.
But we don't stop at "standard." We provide the flexibility to customize pin layouts to suit your project's precise needs. Whether you need a different well-plate configuration or have specific requirements, we're here to help you achieve your research goals. Explore our options and tailor your pin spotter to perfection.
