Dispensing Capillaries
Precision Starts Here.
At the heart of SCIENION’s systems lie two complementary dispensing technologies, sciDROP PICO and sciDROP NANO, each powered by its own family of precision capillaries. Piezo Dispense Capillaries (PDC) enable picoliter-scale, pulse-driven droplet generation, while Nano Dispense Capillaries (NDC) support nanoliter-to-microliter jetting through electromagnetic micro-valve control. Together, they form the foundation of our reproducible, non-contact dispensing ecosystem.
Every workflow demands tailored performance. That’s why SCIENION provides a broad portfolio of PDC and NDC options, covering multiple orifice sizes, flow ranges, and surface coatings to match diverse applications, from precise microarray spotting and biosensor production to reagent loading for diagnostic and microfluidic devices. Designed, manufactured, and quality-controlled in-house, SCIENION’s dispensing capillaries deliver consistent accuracy, long-term stability, and seamless scalability from R&D to manufacturing.
Benefits
Both Piezo (PDC) and Nano (NDC) Dispense Capillaries power SCIENION’s sciDROP technologies, delivering stable, reproducible droplet formation across picoliter to microliter volumes. Trusted by leading diagnostic and research manufacturers, this precision ensures consistent performance from the first test to full-scale production.
Choose from a wide selection of PDC and NDC options, different orifice sizes, coatings, and flow characteristics, to match your liquid type and workflow. Whether handling aqueous buffers, organic solvents, or complex protein mixtures, SCIENION provides the right capillary for optimal results.
Each dispense capillary is manufactured under strict quality control to ensure consistent geometry, stable surface properties, and long lifetime. Combined with automated droplet monitoring and calibration in our instruments, this guarantees traceable performance for regulated and high-throughput environments.
SCIENION’s capillaries are designed for seamless use across sciFLEXARRAYER and cellenONE instruments, supporting workflows from microarray printing to single-cell isolation and microfluidic device production, all with the same core precision–dispensing DNA.
With proper care and cleaning, both PDCs and NDCs offer long reusability and minimal waste. This durability reduces consumable costs and environmental impact while maintaining the accuracy and reliability required for advanced life-science manufacturing.
CHOOSING THE RIGHT DISPENSING CAPILLARY
The Selection Guide can be used to generally select an appropriate PDC, for the sample to be printed – as it shows:
- The drop size and coating options suitable for a selection of typical samples
- Typical aqueous buffer systems, e.g. PBS, carbonate buffer, SSC
- A selection of suitable organic solvents as buffer additives with a content < 50%
- A selection of suitable organic solvents with a content > 50%
PDC Coating Type 1:
Recommended for samples in aqueous solutions or in print buffer containing organic solvent
PDC Coating Type 2:
Recommended for samples in aqueous solutions, in print buffer containing organic solvents or in organic solvent.
PDC Coating Type 3:
Recommended for samples in aqueous solutions or in print buffer containing organic solvent.
PDC Coating Type 4:
Recommended for samples in aqueous solutions, in print buffer containing organic solvents or in organic solvent.
Single Cells to Microarrays: Powered by the Same Precision
Whether you’re printing microarrays with SCIENION sciFLEXARRAYER or isolating single cells with Cellenion cellenONE, the same PDC technology ensures consistent droplet formation and dependable precision across applications.
