My son took advance Chemistry last year and this was a required chemical. The packaging was excellent and it worked perfectly for the experiments he had. There was more than enough to complete all the labs he had for it, in fact, we still have some for my daughter to use in her Chemistry course. I would definitely buy this again.
It has always been a pleasure doing business with Home Science Tools. Over the past few years my experiences have been nothing but positive. Great products, fast shipping and excellent packaging. I look forward to many more years of business!
