• One refill box contains 1000g of component A and 1000g of component B
• With 1 set of A and B, approximately 525 grams of CO2 can be made

The reactor set makes pure CO2 from a chemical reaction. Just add parts A & B in equal measures to the cylinder and within a short period of time, you are making your own CO2 safely at home.
