Screw Caps

New screw caps for Spectroquant® cell tests

Safer conditions. Easier handling. Better results.

If you're in the chemical or food industry or work in wastewater analysis, we at EMD have just made your job a little easier. We're introducing our innovative new screw caps for Spectroquant® cell tests - significantly stronger and smarter than the caps you're used to.

Accurate results wherever and whenever you need them

EMD's photometric test kits and instruments are already proven to deliver accurate results wherever and whenever you need them. And by redesigning our screw caps and molding them out of a super-strong material, we've made a good thing even better. While other brands use polypropylene (PP), our new screw caps are made of polyvinylidene fluoride (PVDF), which is much more resistant to chemicals used in the digestion procedure.

Key benefits:
  • Peace-of-mind design: With a higher chemical resistance, you can rest assured that test ingredients – like the chromium sulfuric acid in Chemical Oxygen Demand (COD) tests – will not attack the packaging and jeopardize your lab work.
  • Rock-solid test results: Boiling samples? No problem. A newly designed inner seal prevents liquid loss and the PVDF material withstands temperatures up to 140ºC.
  • User-friendly handling: To “cap it off,” we’ve added a knurled, expanded surface for an easier grip. This makes it more comfortable to screw the caps.
