The smartest way to refill your empty TIPACK box & Reload block. Racks are individually wrapped to ensure the best cleanness and to facilitate rack handling. Use 45% less plastic than a regular rack box. Racks are fully autoclavable. The racks are color-coded to differentiate tip models and indicate the compatible Gilson pipette models. Remove blister packaging before autoclaving. Autoclaving conditions: Moist heat / 121°C / 20 minutes / 1 bar
