WHY CHOOSE US?
The Guaranta services are tailored for R&D leaders who:
-
Are developing innovative products for life science, healthcare or biomedical markets.
-
Their technology includes miniaturisation, microfluidics or lab-on-a-chip elements.
-
Want to decrease the risk of non-optimal product design in terms of product functionality and manufacturability.
We can support you throughout your product development cycle by providing technical designs and expert guidance. We help overcome challenges with product design, process development and manufacturing, so you can deliver your projects on-spec, on-time and on-budget.
OUR SERVICES
Our services support you across different R&D stages of product development, from preparing technical designs for your prototypes to designing products and processes for mass manufacturing.
Being an independent consultancy, we provide unbiased advice on the design options, experimental validation, choice of materials and manufacturing technologies.
From Idea to Experiment
For those who have a product idea but need a technical design for a proof-of-concept or a prototype so it can get tested.
Integrated Microfluidics
(Lab-on-a-chip)
For those who want to integrate multiple processes into a miniaturized, multifunctional product.
Fluidic System Architecture
For those who need a comprehensive solution to control and automate fluidic handling in a microfluidic device.
Design for Manufacturing (DFM)
For those who want to minimize manufacturing costs while ensuring high product quality and reliability.
Micro- and Mass-manufacturing
For those who require micro-manufacturing tool sets or aim for mass production.
Set-up of Lab and Workshop
For those who are setting up an efficient laboratory or a workshop, in need of expert advisory, conceptual sketches and budget breakdown.
