Prevent evaporation with self-closing plate seal
- RAPID Slit Seal -

The RAPID Slit Seal is proven to prevent solvent evaporation and cross-contamination.  It allows easy insertion and withdrawal of pipette tips and sampling needles without catching and dragging.

  • Self-closes instantly.
  • No cross-contamination between wells.
  • Allows next day analysis.
  • No adhesive on well spots.
  • Pipette tips insert easily with less friction.
  • Reduce solvent evaporation.

Product Introduction Video


“We run quite a lot of samples with our mass spec, which is why some people in our lab prefer to use the autosampler plate for the samples so that they can just run 96 samples in one sitting…The plate seals are working perfectly for our application.”

Testimonial from Danica-Mae Manalo, Proteomics Lab, Cedars-Sinai Medical Center
