LC50 Aquatic Toxicity Kit

You are introduced to static toxicity tests used by the EPA and other health and environmental organizations to set water quality standards. During the lab, students prepare various concentrations of ammonium sulfate, a fertilizer component, and introduce Daphnia magna into their solutions. After 24 hours, students observe the mortality percentage of Daphnia in each concentration and determine the LC₅₀ of ammonium sulfate. Kit accommodates a class of 30 students working in groups of 6 and includes a prepaid coupon to request the perishable material later at your convenience. Contact us or return the coupon at least 2 weeks prior to requested delivery date to ensure prompt arrival of material.
