Use a 125 mL Erlenmeyer flask to collect the distillate. Transfer the distillate
periodically to a 100 mL graduated cylinder (you will need a second flask or beaker to collect the drops which fall during this transfer); this way, if any material foams over into the condenser, the entire distillate will not be contaminated. If a portion of the distillate is contaminated in this way, you will have to re-distill that portion. Collect 100-120 mL of distillate.
