10 mL Short Stem Transfer Pipets, LDPE, Natural — Graduated, 250/Bag (230-1597-020)
These 10 mL short stem transfer pipets from Caplugs® Evergreen are molded from low-density polyethylene (LDPE) and supplied non-sterile in a convenient 250/Bag bulk format for high-throughput clinical and laboratory workflows. The short stem geometry provides stable, controlled aspiration from wide-mouth specimen containers, reagent bottles, and bulk specimen cups, while the 45 µL/drop calibration offers a reliable semi-quantitative volume reference for routine transfer applications. LDPE construction delivers the flexibility needed for complete sample expulsion with low residual retention.

Frequently Asked Questions
Are these transfer pipets sterile?
No — these pipets are supplied non-sterile in 250/Bag bulk packaging. They are intended for routine specimen transfer, reagent dispensing, and other general laboratory applications that do not require sterility assurance.
What does the short stem design offer compared to a long stem transfer pipet?
The short stem geometry provides a more stable, controlled aspiration angle when working with wide-mouth containers such as specimen cups, beakers, and reagent bottles. It reduces stem flexion during large-volume transfers, which helps minimize aspiration errors and improves handling comfort in high-throughput workflows.
How precise is the 45 µL/drop calibration?
The 45 µL/drop figure is a semi-quantitative reference calibrated for the tip geometry of these pipets. It is well suited for routine laboratory transfer tasks but should not be substituted for volumetric-grade pipetting in applications requiring tight accuracy tolerances.
Is LDPE compatible with the biological specimens commonly handled in a clinical lab?
Yes — LDPE is broadly compatible with aqueous clinical specimens including urine, serum, plasma, whole blood, and CSF, as well as standard laboratory buffers and dilute acids and bases. For applications involving concentrated organic solvents, verify compatibility before use.
