These 1L PYREX® blunt tip cones are for use with heavy sediments, where ability to read small volumes is unimportant. Graduated from 0 to 1 mL in 0.1 mL divisions, 1 to 10 mL in 0.5 mL and 10 to 40 mL in 1 mL; also marked at 1000 mL. The blunt tip increases its ruggedness and cleaning ease.

This PYREX® general purpose condenser has a 24/40 Standard Taper inner joint at the bottom with a drip tip. Although the condensing area per unit length of the 400mm long jacket is low, the large capacity water jacket gives efficient cooling. They can be used for either distillation or extraction. Condenser tubulations are approximately 10mm O.D.
