Functional highlights

  • Freely programmable drop volumes from 0.5 µl (approx. Ø 1 mm) to 33.5 µl (approx. Ø 4 mm)
  • Temperature range cryochamber: 0 to -25°C
  • Temperature accuracy: ± 0.1°C
  • Temperatures of cryochamber, seawater reservoir and drop valve independently adjustable
  • Sample holder with different angles from 0° to 60

Infrastructure process from conception to operation

•  Cryochamber for precise tempering of the coated sample

•  Sample holder for different sample angles

•  Temperature control by PID for cryochamber, seawater reservoir and drop valve

•  Freely programmable drop volumes
