Diagnostic components - tight tolerance converting
Manufacturing processes for accurate diagnostic testing devices
Realiable and extremely accurate membrane based diagnostic testing is used by millions of patients globally on a daily basis.
Material converting for diagnostics
The development of accurate in-home and over-the-counter diagnostic test products for a wide range of healthcare issues has driven intense development of multi-layer laminate construction of specialist adhesive coated films and space tape lamination. PolarSeal has been actively involved in this fast-growing market sector from the start, and now plays a major role in the development and manufacture of new diagnostic test strips.
Applications overview
Reliable and extremely accurate membrane-based diagnostic medical test strips are now used by millions of patients globally daily. Diagnostic products include blood coagulation, blood glucose, cholesterol, ischemia, heart failure, blood pressure, urinary tract infections as well as testing for ovulation and pregnancy.
By utilising cutting edge bespoke converting capability and an unparalleled experience of the materials required, PolarSeal can provide the manufacture of these critical diagnostic products to the tightest tolerance requested whilst serving the mass volume required.
PolarSeal is fully qualified in this advanced technical field and can offer great flexibility in terms of the options possible in respect of the design and production specifications of these specialist products which may include:
- Membrane-based diagnostic requirements – non-migratory inert adhesive systems for compatibility with assay-type diagnostic testing devices
- Capillary flow – various thickness materials used to facilitate volume requirements by utilising varying sized channels to regulate the amount of specimen being tested
- Hydrophilic characteristics – to customize the flow of specimen by the selection of the various coatings and adhesives available, by the control of surface tension required to reduce the test time and sample size through offering enhanced wicking
- Versatile processing capability – conformable and ease of die-cutting
- Matching the surface energy of biological fluids
- Tape construction – single coated, double-coated, or transfer film
- Diagnostic test strip
