Wi Medical Device Development

Custom Reagent Blister Packaging: Design & Manufacture

The world of sample-to-answer molecular diagnostics and sophisticated IVD tests demands fully integrated assays complete with reagents and buffers on device.  This demand lead Wi to develop an effective method of designing, rapid prototyping, filling, and sealing blisters.  Additionally, Wi has developed novel methods of opening and dispensing the fluids under control and with minimal force.  This translates to lower power requirements for instrumentation and tighter control of the assay being executed.

Wi has over 13 years of experience developing and producing blisters. We are capable of producing practically any quantity, shape, or size of formed blister to integrate into your application. We are just as happy to deliver a small quantity of 100 sample parts as we are to engage in long-term production contracts for tens of millions of blisters.
