Very likely yes. Darwin was built precisely for this. Many of the best microfluidic instruments are designed and manufactured in Europe and simply not distributed in the US. Our catalogue covers 70+ brands including Elveflow, Micronit, Bartels, Emulseo, and many others that have no US distributor. If you know the product, send us the reference and we confirm availability and lead time within one business day.

Yes, this is one of the most common requests we handle. Our technical team. made up of PhDs and engineers with hands-on microfluidics experience. can review your application, budget, and experimental requirements and propose a complete equipment list. We cover everything from flow control and chips to tubing, connectors, surfactants, and imaging accessories. Contact us at contact@darwin-microfluidics.com or +1 (617) 366-1212 to get started.

Yes. Chip selection is one of the most common technical questions we receive. Our team can advise on material (PDMS, glass, COC, silicon), channel geometry, inlet configuration, and compatibility with your fluid handling setup. Send us your application details. target droplet size, fluid type, flow rates, detection method. and we recommend specific chips from our catalogue with reasoning behind each choice.

Start by contacting our technical team with your target particle size, lipid formulation, and required throughput. We recommend a complete system: the right microfluidic chip for nanoprecipitation, a flow controller or syringe pump matched to your flow rates, Emulseo surfactants if needed, and the tubing and connectors for a leak-free setup. We have helped multiple US biotech teams build LNP workflows from scratch and can share application notes from comparable setups.

We respond to all technical enquiries within one business day. usually faster. You can reach us by email at contact@darwin-microfluidics.com or by phone at +1 (617) 366-1212. You talk directly to a member of our scientific team, not a call centre representative reading from a script. For urgent orders or time-sensitive experiments, call us directly and we prioritise your request.

Yes. We work regularly with US university purchasing departments, NIH-funded labs, and corporate procurement teams. We can issue formal quotations, pro forma invoices, and W-9 documentation, and we support purchase order-based transactions. If your institution requires vendor registration, contact us at contact@darwin-microfluidics.com and we guide you through the process.

We stand behind every product we sell. If something does not perform as expected in your application, contact our technical team and we will troubleshoot with you directly. In most cases we can identify whether the issue is with setup, compatibility, or the product itself, and we work with you and the manufacturer to find a solution. We would rather fix the problem than lose a customer.

Yes. For recurring orders, large single purchases, or multi-item lab setups, contact us directly at contact@darwin-microfluidics.com or +1 (617) 366-1212 to discuss pricing. We work with core facilities, CROs, and biotech companies on custom pricing arrangements, and we can set up standing orders for consumables like surfactants, tubing, and chips that you order regularly.
