Fully Skirted Square 24-Deep Well Microplate with Disposable Cover (PR-CR1424-CDC)

 

Older version of PR-CR1424-CL. Mainly used with the Thermo Fisher Cytomat Selector series and for further automation uses.

  • Pyramid bottom for easy centrifugation (pellet in center well)
  • Comes with a disposable low-evaporation sandwich cover (1.2 mm holes) on top
  • Mainly used for automation purposes where the PR-CR1424-CL ridges are an issue 

Square 24-Deep Well Microplates with PS Lid (PR-CR1424-CL)

  • Used for leachable-sensitive cultures, such as the cultivation of CHO- and HEK cells
  • Pyramid bottom for easy centrifugation (pellet in center well)
  • Stackable two high in our universal clamps
  • Barcoded version available for sample tracking (PR-CR1424-CLB)

Square 24-Deep Well Microplates with Disposable Cover (PR-CR1424-CLDC)

  • Low evaporation disposable covers (1.2 mm holes) mounted on top
  • Pyramid bottom for easy centrifugation (pellet in center well)
  • Stack three high in our universal clamps 

Grey/White Square 24-Deep Well Microplates with a Transparent Bottom (PR-CR1424-DG)

  • Has a transparent bottom and is thus suitable for use in the Growth Profiler
  • Light grey to prevent cross-talk between wells, ensuring the most accurate measurements, even at lower ODs 

Extra Tall 4-Position Universal Clamp (PR-CR1812DC-L)

 

For use with 24-Deep Well Plates and disposable covers.


S
pecial clamping system with ultra-high pillars to support triple-stacked plates and disposable covers, such as the PR-CR1424-CLDC series. Fits various shaker platforms.

 

If stainless covers are used, only two 24-Deep Well Plates and covers are to be stacked (to prevent a too high center of gravity)
