We are contract manufacturers specializing in injection-molded nano- and micro-scale microfluidic consumables.  Centrally located to major biotech hubs in California, Vantiva Precision BioDevices partners “locally” with clients, providing prototyping through scale manufacturing services.

A wholly owned-division of Vantiva with over 35 years injection-molding/molding experience, we offer end-to-end solutions for mass-manufacturing scale-up in multiple facilities; custom-packaging capability in Poland, Mexico and Australia; and simplified logistics with our own worldwide shipping capability.

Optical Imaging Flow Cell – Clear-to-Clear Laser Welding

The Requirement: A hermetically sealed flow cell with clear cover and channel layers with uniform channel height and no adhesive contamination.

Solution: Vantiva’s unique contour laser welding technology seals clear-to-clear materials, no darker energy absorbing layer is needed resulting in a clear optical path.

Precision High Pressure Droplet Generator – Solvent Bonding

The Requirement: A complex, optically clear droplet generator and pillar array design is required for precision drop size, distribution and segregation operating under high pressure.

Solution: Vantiva’s solvent bonding enabled the assembly of clear-to-clear materials avoiding cover films with adhesives that could overflow and impact droplet formation, biocompatibility and different surface energies.


The Requirement: A cost effective and reproducible alternative to silicone as a substrate for a precision nano-pore microarray used for genomic analysis.

Solution: Vantiva provided reproducible injection molded microarrays with uniform spaced pores as small as 20um in diameter performing well in the NGS application and at a reduced cost.
