Life Sciences

Many life science applications can benefit from the use of specific transfer pipettes designed to make the task easier and more efficient.

Use of Pastettes in Life Science Applications

For cells in flasks and tubes, use large volume, long pipettes:

Procedures Pastettes Non-Sterile Sterile Singles Sterile 10’s Sterile 20’s
  • Sub-culturing
  • Harvesting
  • Sampling 15, 50, 100ml tubes and flasks
  • Remove supernatant and media from cell cultures
  • Wash cells
  • Post centrifugation/trypsinisation to remove cell layers

  • Prevent cells from getting stripped / sheared when removed or transferred
  • Triturate cells
  • Isolate Platelets from blood and wash

  • Loading gels
  • PCR work
  • Aspiration of media/reagents/supernatant from microwell plates
  • Feed hybridomas
  • Protein assays
  • Lipid extractions
  • Atomic absorption spectroscopy reagent preparation
  • Careful separation of supernatant in centrifuge tubes
  • Dropwise additions to culture plates
 Extended Fine Tip LW4233 LW4238 – LW4232
Standard Micro LW4020 LW4021 – LW4023
Large Bulb Micro LW4252 – – LW4255

Eliminate steps, use large bulbed, narrow stemmed pipettes:

  • Reaction chamber
  • Storage ampoule
  • Portable aliquoting
  • Pre-mix, collect, heat-seal, freeze, store, or incubate and dispense: Reagents, buffer solutions, Protozoa, nematode larvae, marine eggs, seeds, Anti-serum, urine
