This life-sized 2-part model is a realistic representation of the left and right human lungs. All external features rendered in detail.

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.

Balance Compact 200g/0.1g and 7.05oz/.01oz OhausCs200

Dual Spring Scale, Ohaus, 2000gx50g, 20nx0.5n.

These spring scales provide direct readings for both force and measurement experiments. The transparent tube allows full view of the action of the spring. They are color coded for easy use, calibrated in both grams and Newtons and feature readings that range from 100 g/1 N to 5000 g/50 N. The fusion-welded tubes are durable and are great for force and measurement experiments. The scales are 10" long at rest, 13" long fully extended. Image may vary.
