Thawing cryovials with a water bath introduces contamination risk, operator variability, and guesswork, all at the worst possible moment for your cells. Macaroni Thaw eliminates all of that.
                                                                                                                                                       
Insert your vial, walk away. In under 3 minutes, Macaroni Thaw delivers a controlled, water-free thaw, automatically detecting completion and alerting you with a clear LED and audio signal. Temperature is kept at or below 37°C throughout, protecting even the most sensitive cell types from thermal shock.

No water. No timing. No variability between users. Just consistent, reproducible results every time, whether you're working with routine cell lines, primary cells, iPSCs, or organoids.
Designed for professional laboratory use, Macaroni Thaw replaces the most inconsistent step in your cryopreservation workflow with a standardised, automated process that runs the same way every single time, whoever is at the bench.

  • Water-free thawing that replaces the 37°C water bath with a clean, automated process, removing the need to maintain or decontaminate a bath
  • Consistent, repeatable results. Automated thaw detection thaws every vial to the same endpoint and removes user-to-user variability
  • Very low contamination risk thanks to the dry, sealed-vial workflow
  • Patent-pending thaw detection technology with a thawing profile equivalent to a 37°C water bath heating rate
  • Fast, hands-free operation. Typical thaw under 3 minutes, with automatic vial detection starting the cycle for you
  • At-a-glance LED status display. A 12-LED clockface plus centre status LED show warm-up, thaw progress, completion
  • Adjustable thaw threshold. Six levels above and below the default to suit your vial type, cryoprotectant and fill volume
  • Auto sleep mode for low-power standby after 60 minutes idle
  • Compact, lightweight benchtop footprint (19 x 12 x 7.5 cm, 0.8 kg without power supply)
  • Designed and manufactured by Grant Instruments in the UK
