Freedom Rocker BlotBot 240


The Freedom Rocker™ BlotBot®is an automated blot washer. Using a microprocessor for precise timing and dispensing, it automatically processes blots and gels in a consistent manner, every time. It frees you from babysitting your samples.


  • Unattended dispensing and aspiration of liquids. Only requires an electrical outlet – no vacuum, pressurized air or gas, or additional pumps required.
  • Can recover reagents, such as antibody solutions, separately from each gel or blot.
  • Drip proof quick-release connections.
  • Adjustable Parameters for each protocol step include: rocking speed (5 to 40 cycles per minute) reagent/solution rocking time (1 min to 90 hours) dispense volume (10 to 150 ml) up to 10 repetitions per step clearing rinse option
  • Patent pending technology. Rocking continues after the final rinse and the wash buffer remains in the trays to prevent the blots or gels from desiccating
  • Built in the USA for years of trouble free use.
  • Uses existing protocols. Programming is easy and follows standard protocols steps. Programs can be up to 9 steps where each step is an immersion in a reagent (e.g. antibody) or a series of washes.
  • In each step reagents or buffer will be dispensed and aspirated to all the trays simultaneously, for consistent processing of all the blots and gels.
  • The minimum volume required to fully cover each mini blot is 3.5 mL.
  • A clearing rinse can be activated to provide a quick rinse to get the final drop of reagent after each wash or reagent immersion. Quiet.
  • The removable trays can be washed. Replacements can be ordered separately.
  • A bottle of buffer is connected to the BlotBot with a hose and leak-proof quick-connector connections.
