Globe Scientific 138005 Bellows Transfer Pipettes 15.0mL Graduated
Globe Scientific 138005 bellows-style transfer pipettes combine the controlled dispensing of a bellows (accordion) bulb with graduation markings to 5mL for approximate volume measurement. The 15.0mL capacity handles larger sample volumes while maintaining the precise drop-by-drop control that bellows pipettes are known for. Made from medical-grade LDPE. Ideal for histology staining, reagent dispensing, and clinical sample transfer where controlled delivery and volume estimation are both needed.

Frequently Asked Questions
What is the difference between the 138005 and the 138002 bellows pipette?
The 138005 is a larger 15.0mL bellows pipette with graduation markings to 5mL for approximate volume reading. The 138002 is a smaller 7.0mL non-graduated bellows pipette. Both use the same accordion-style bulb for controlled dispensing.
How accurate are the graduation markings on bellows pipettes?
Graduation markings on transfer pipettes are approximate and intended for estimation only. For precise volume measurement, use a calibrated micropipette with disposable tips. Transfer pipette graduations typically have an accuracy of plus or minus 10-15 percent.
Can I use bellows pipettes for organic solvents?
LDPE bellows pipettes are compatible with most aqueous solutions, dilute acids, and dilute bases. They are not recommended for concentrated organic solvents like acetone, chloroform, or toluene, which can dissolve or swell polyethylene.
