10 mL Graduated Transfer Pipets, LDPE, Natural — Caplugs® Evergreen (230-1599-020)
These 10 mL low-density polyethylene transfer pipets feature printed volume graduation markings and a 50 µL per-drop calibration, making them well suited for semi-quantitative specimen transfer and reagent dispensing in busy clinical and research laboratories. Supplied non-sterile in bulk (250/Bag), the LDPE construction delivers the squeeze flexibility needed for complete sample expulsion and low residual volume. Part number 230-1599-020 is a workhorse consumable for any lab requiring reliable, single-use liquid transfer at volume.

Frequently Asked Questions
Are these transfer pipets sterile?
No — they are supplied non-sterile. For workflows that do not require a sterility guarantee, such as routine urinalysis, chemistry specimen transfer, or reagent dispensing, non-sterile transfer pipets are standard practice and offer a more economical bulk supply option.
What does the 50 µL drop size mean, and how is it useful?
The 50 µL/drop calibration means each drop expressed from the tip delivers approximately 50 µL, providing a simple semi-quantitative volume reference without a separate pipettor. This is particularly convenient for drop-count reagent additions and specimen dilution steps in routine clinical workflows.
Can these pipets handle biological specimens such as urine, serum, and whole blood?
Yes. LDPE is non-reactive with the full range of common clinical specimens — including urine, serum, plasma, whole blood, and CSF — as well as standard laboratory buffers and dilute acids and bases, making these pipets appropriate for the broad specimen mix encountered in clinical pathology and reference labs.
Are the graduation markings permanent and legible throughout use?
The volume graduation markings are printed directly on the pipet during manufacturing. Under normal single-use handling conditions the markings remain legible for the duration of each transfer; because these are intended as single-use disposables, long-term print durability is not a practical concern.
