5. Operating Exclusions

The instrument is suitable for dispensing a wide range of liquids, excluding but not
limited to:
– Liquids which attack FEP, ETFE, PFA, PTFE and PVDF;
– Solutions containing hydrofluoric acid, since they attack borosilicate glass;
– Suspensions, containing solid particles;
– Solutions which decompose and form solid particles (e.g., Biuret reagent);
– Substances which undergo catalytic transformation or react with Platinum-Iridium

(e.g., H

2

O

);

– Carbon disulfide, as this media inflames easily
