The AutoMimo 1200 is an automated sample preparation system for use with the Autof ms1000 MALDI-TOF which can effectively solve the problem of poor repeatability and uniformity caused by manual micro-dosing errors. High-efficiency air purification system and regular ultraviolet disinfection function protect the safety of operators and laboratories, and effectively reduce biological safety risks. At present, the AutoMimo can be adapted for use on all mainstream mass spectrometry spot templates.
