Borosil® brand Pipettes are made of specially-selected, heavy wall, machine-drawn, borosilicate accurate, bore glass tubing. They have precision formed jets, and bevel ground ends that resist chipping.

• Graduated to tip
• Two top rings indicate to deliver (TD)
• Permanent amber stain markings

The graduations are made in durable white enamel or amber stain that is resistant to laboratory reagents and repeat washing. All Pipettes are individually measured and then marked. The uniformity of bore ensures accuracy between any two readings and they are autoclavable. These pipettes are graduated to the tip and the two rings at the top indicate that the pipettes are calibrated to deliver from any graduation line down to the tip. Permanent amber stain is diffused into the surface of the glass for markings for better visibility and durability.
