Globe Scientific Narrow Stem Transfer Pipettes — Thin-Profile Access for Small-Opening Vessels Globe Scientific narrow stem transfer pipettes feature a reduced-diameter stem that f its into vessels with restricted openings where standard transfer pipettes cannot reach. Available in short stem (65–85mm) and long stem (155mm) configurations with capacities from 1.2mL to 15.0mL, these disposable polyethylene pipettes serve applications ranging from microcentrifuge tube work to sample recovery from narrow-neck flasks. The narrow profile also reduces dead volume in the stem, improving sample recovery when working with limited specimen volumes. Order from LabSupplies.com, an authorized Globe Scientific dealer.

Common uses include transferring samples from microcentrifuge tubes without disturbing pellets, accessing cryovials and small-diameter culture tubes, recovering specimens from narrow-neck volumetric flasks, and working with pediatric blood collection tubes. The short stem versions (65mm and 85mm) are optimized for microtubes and small vessels, while the long stem versions (155mm) reach into standard test tubes and centrifuge tubes. Frequently Asked Questions {"@context":"https://schema.org","@type":"FAQPage","mainEntity":[ {"@type":"Question","name":"What is the difference between narrow stem short and narrow stem long transfer pipettes?","acceptedAnswer":{"@type":"Answer","text":"Short stem versions (65–85mm) are designed for shallow vessels like microcentrifuge tubes and cryovials. Long stem versions (155mm) reach into deeper vessels like standard test tubes and centrifuge tubes. Both feature the same reduced-diameter stem for accessing restricted openings."}}, {"@type":"Question","name":"Can narrow stem pipettes fit into microcentrifuge tubes?","acceptedAnswer":{"@type":"Answer","text":"Yes. The 1.2mL short stem (65mm) and 4.0mL short stem (85mm) versions are specifically designed with a thin enough profile to access 1.5mL and 2.0mL microcentrifuge tubes."}} ]} Show more
