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 fits 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.

When to Use Narrow Stem Transfer Pipettes
Narrow stem transfer pipettes excel in applications where vessel openings are too small for standard-bore pipettes or where dead volume must be minimized. 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.
