Produto muito bom. A caixa de papelão da embalagem é bem fraca, mas veio tudo integro. Recomendo.
It is a nice product, everything is there and in good condition. I think the set was used before or washed before delivery(it had some spots left from drying). I have no problem with that. Specs: The thermometre is on 0-100 scale C. The glassware looks to be borosilicate( Not sure, I only used it in water bath heating at 78 C). I only did normal ethanol distillation with this kit( I know that for this use I didn't need the fractionating column) Overall a nice kit, good for chemistry beginners and for small quantities distillation. Some tips for beginners in chemistry or in distillation: -Because the glass type is unknow, handle it with care(don't use it with a Bunsen). -Fill the boiling flask at half capacity, if you need to make more runs of distillation. -Make sure you can remove the heating source in case of a violent reaction. -If not obvious don't fill the flask with solid materials, It will crack when cooling . I hope this review was helpfull.
