This is a complete and economical kit for obtaining samples from flowing water for further study in the lab. The equipment provided is durable and reusable and does not require extensive training. The D-frame net is lightweight and practical, with a 30-inch handle for easy handling by students. Six (6) are provided, so several groups of students can obtain samples at once. The wide-mouthed sample jars (12) are a generous 500 mL in size for holding your sample till you get back to the lab. Constructed of durable polypropylene, they are square in shape so they won't tip or spill. Our turbidity tube is student-sized at 60 cm in length and functions like a miniature secchi disk to measure water clarity. We also provide one (1) armored glass thermometer of high accuracy for taking the relevant temperatures of air and water; and six (6) 500 mL plastic wash bottles for rinsing down equipment in the field.
