PRIMA™ membranes are plastic cast memebranes with fast flow rates.  PRIMA™ provides an easy answer to developers who want the fastest result or who are working with highly viscous samples or that contain high particulate loading.

Features and Benefits

  • Direct-cast, large pore nitrocellulose membrane with exceptional cross-web and down-web consistency

     Superior sensitivity, ideal for highly specific applications.

  • No treatments post-manufacture

     Uniquely homogenous membrane.

  • Rapid rewetting

     Easy absorption of all sample types.

  • Extensive range of flow rates

     Meets the requirements of even the most difficult assays.

PRIMA™ 40
Fastest-wicking plastic-cast membrane for use with the most viscous samples or samples that contain high levels of particulates.

PRIMA™ 60 
Plastic-cast membrane.  A vest fast wicking membrane for use with highly viscous amples, e.g., undiluted serum.

PRIMA™ 85 
A general-purpose membrane for use with most sample types.

PRIMA™ 125
A membrane with very easy handling requirements that gives good line intensity for use with low viscosity samples.

Standard Sizes
Available in 50m rolls of 25mm width; for other sizes please inquire.
