It has continuous graduations up to 1000mL, ideal for tests where a high volume of settled matter is present. Graduated in these divisions: 0-2mL in 1/10mL, 2-10mL in 1/2 mL, 10-40mL in 1mL, 40-100mL in 2mL, and 100-1000mL in 50mL. Leak-proof polyethylene plug permits easy withdrawal of sediment for gravimetric analysis and simplifies cleaning. Top diam. 12cm (4.7") x 50cm (19.7") high.
