Question about item

Hello, I am looking to acquire a ductless fume hood for chemical purposes only in a Geology research laboratory. The chemicals that will be used are HCl at several concentrations (6M the highest), NaOH, NH4OH and Oxalic (0.4M). There will no heating or fuming, and some evaporation might occur associated to the procedures and it will be with small amounts (.20 ml).  I looked to the model Captair flex XL 391. Would be possible to suggest me other models (or confirm if this is an adequate one) and costs of ourchase associated? Thank you. Paula M Figueiredo pdossan2@ncsu.edu 513-834-4946
