Borosil brand pipettes are manufactured from specially selected heavy-wall machine-drawn borosilicate accurate bore glass tubing. They have precision formed jets and bevel ground ends to resist chipping. The graduation marks are in durable white enamel or amber stain, both are resistant to normal laboratory agents and repeated washing. All the pipettes are individually measured and then marked. Accuracy is ensured between any two readings, because of uniformity of bore. The pipettes can be autoclaved and if necessary can be flamed for sterilization.
Easy one hand operation. Rotation of the thumbwheel draws or dispenses the liquid with precision and ease. By depressing the side lever the entire contents can be dispensed rapidly. Accepts glass and plastic pipettes. Color coded for sizes.
