This is a complete and economical kit for obtaining samples of phyto and zooplankton from lakes and ponds for later study in the lab. The apparatus we provide is durable and reusable. Our basic water bottle needs no messenger. It is constructed of PVC with soft rubber seals and 20 m of line on a styrofoam float that will bob to the surface if dropped. We provide twelve (12) 250 mL sample bottles for transporting samples back to the lab. Our plankton net is the real thing: constructed of genuine Nitex® 8
