Modular Microcentrifuge Tube Ice Rack System

thingiverse

Save money while maintaining sample stability with the Modular Microcentrifuge Ice Rack System! This simple, low-cost alternative requires just a printed lid, water, and a styrofoam cup for chilling your microcentrifuge tubes during lab procedures. Simply print the desired lid in Tinkercad, fill a 4"-mouthed styrofoam cup with cold tap water, place the lid on top, and freeze until needed. The system effectively cools samples to 2-6°C within minutes and maintains temperature for an hour. Note that longer freezing times may be required for complete ice formation. This innovative design ensures minimal condensation and contamination risks by keeping tube shafts submerged in water. Stay tuned for additional lid designs catering to different microcentrifuge tube sizes!
