Serological Pipets, PYREX Accu Red, Color

• Calibrated "to deliver"
• Large tip opening to allow more rapid intake and delivery of suspensions and viscous materials
• Color-coded by size for easy identification and sorting
• Accu-Red graduations are permanently fused into the glass

Two rings at the top indicate the pipet is calibrated “to deliver” its total capacity when the last drop is blown out.
