Three-position thermal unit that integrates with the Beckman iSeries liquid handlers including the Biomek i5 or i7 decks. Expanded plate capacities are available upon request. The unit will accommodate any standard consumable plate or small tube racks with the corresponding MéCour thermal insert that provides uniform temperature distribution to all plate wells or small tubes and vials. Operating temperature range for this unit is +100°C down to -65°C. MéCour now provides dry air purging systems that integrate with the thermal portion of the system to insure unwanted condensation is eliminated.
