Size:5.8mL 1mL Large Bulb Transfer Pipette Graduated, With Bulb Draw of 3.4mL These graduated large 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: 5.8ml. Bulb Draw: 3.4ml. Dispensing Rate: 25 Drops/ml. Stem Diameter: 4.6mm. Length: 6-1/10 inches (15.5cm). Samco Scientific #: 222.

More versatile than expected
I found that with a heat gun on a medium-low setting I could soften and draw the tube creating a much smaller tip. I needed a few pipettes for one purpose but had to buy in bulk. Now I am finding many other applications where I need to apply small drops or need to place a liquid in a hard-to-reach location.

Nice inexpensive pipettes
These pipettes do exactly what they are designed to do. These are the 1mL pipettes with the small bulb which I like because it gives me finer control when attempting to measure liquids using the graduations on the tube. I have used the 1mL pipettes with the large bulb, but they make measurements difficult.I use them for measuring small amounts of hydroponic additives. Having a box of 500 and a cost per unit of less than 4 cents makes it easy to just dispose of them after each use and prevent contamination of the bottled solutions.
