Samco Scientific 212 Polyethylene 3.9mL Graduated 1mL Small Bulb Transfer Pipette, with Bulb Draw of 2.2mL (Pack of 500)
These graduated small bulb type Samco Scientific disposable transfer pipets are made of shatterproof, nontoxic polyethylene. Non-sterile and bulk packed, the single-unit design features a stem which narrows down to a fine tip and a built-in pipet bulb eliminating the need for plugging. Especially useful where more accurate volume measurements are required, the graduation lines allow the accurate measurement of more than one volume. Their low-affinity surface reduces loss of cells and valuable proteins due to binding. They can also be frozen in liquid nitrogen or heat sealed for storage. Graduation Increments: 0.25 - 1.0ml. Overall Capacity: 3.9ml. Bulb Draw: 2.2ml. Dispensing Rate: 25 Drops/ml. Stem Diameter: 4.7mm. Length: 5-1/2 inches (14.0cm). Samco Scientific #: 212.
