Unformatted text preview: by using Spectro (absorbance) machine. In order to use this machine, the machine has to be set to zero the whole time until the vial is put in place. Before the vials are inserted in the machine there has to be another vial with just Alga Grow (Carolina Biol. Supply). But make sure each vial in wiped down with acetone so that it wont affect the absorbance reading and shake all the vials in the shaking machine to get a more accurate absorbance reading. Then after inserting the vial with just Alga Grow and setting everything to zero take off the that vial and put vial one and once done with the reading place back the vial with just Alga Grow to make sure everything is still adjusted to zero. Then insert the next vial and repeat these steps to get the absorbance reading....
