A wide range of caps for closing open-top empty cartridges/columns, to use as a single barrel reaction vessel. Caps are available for vials ranging from 1-150 ml. Caps come in different types (screw, crimp, snap), a range of colours, closed or open for piercing applications with different type of (optional PTFE) liners. Caps are often delivered together with the vials but can also be provided seperately. We will find out which caps fit your vials and needs best. 

For well plates, cap mats for long-term storage, (pre-) pierced fully compatible with your (semi- or automated) systems are available. Please also note our 3M seals and foils in the 'read more' section and the microplate seals for our cappers/sealers. 

 

Besides Cap Mats adhesive foils are widely applied: 

  • Adhesive plate seal with high organic resistance (DMSO, MeOH, AcCN)
  • Embossed surface for easy piercing
  • Easy Sealing & Removable
  • Resealable EPS Seal Solvent Resistant
  • No needle clogging
  • No stickiness to needles of autosamplers
  • Easy piercing and peeling off
  • No residual adhesive on micro plates after peeling off
  • High airtightness
  • No cross contamination between wells
  • Thermal stability between -80℃ and +80℃,
  • Suitable for HPLC, Cold storage, dry freezing.
  • Pre-cut type for manual sealing
  • Size:80mm×122mm
  • Material:Polyolefin, Synthetic adhesive
