Environmental Science— Water Sampling, continued
Water Sampling Bottle
Collect water samples at depths from 1 to 20 meters—ideal for dissolved oxygen testing! Simply lower to sampling depth using a cali- brated line, pull the trip line, and water will flow in and automatically overflow five times for an accurate and representative sample. Collect sample from the removable inner chamber. Lead collar ensures rapid descent and minimizes drift. Thermometer can be inserted into chamber for temperature readings. Includes three 60-mL inner chambers and clear acrylic outer tube. Size 6" L x 31⁄2" W.

Environmental and Science—Pollution
Bacterial Pollution (Coliform)—
Student Laboratory Kit
By: The Flinn Staff
Students will determine the presence or absence of coliform bacteria (indicative of the presence of untreated sewage and potentially patho- genic bacteria) in water supplies. By observing a dramatic color change that occurs in a lactose broth medium, students will determine whether coliforms are present. Includes 25 tubes of lactose broth medium with chlorophenol red indicator, sterile transfer pipets and instructions.
Complete for 25 students tests. Super Value Kit is complete for 75 student tests.
Environmental Pollution—
Student Laboratory Kit
By: The Flinn Staff
Introduce students to air and water pollutants using this comprehensive, hands-on kit. Students will gain a deeper understanding of air quality by performing valuable experiments to detect smoke, particulate mate- rials and acidic gases in air. Safe and easy tablet-type tests are used to explore critical water factors, such as pH, phosphate and ammonia. Kit includes detailed background information, complete instructions and reproducible student handouts.
Complete for 30 students working in pairs.
