1.0 mL Fine-Tip LDPE Transfer Pipets — Natural, 400/Bag (230-1565-020)
These 1.0 mL disposable transfer pipets feature a precision fine tip with a calibrated 20 µL drop size, giving clinical and research laboratories controlled micro-volume delivery without a micropipettor. Constructed from low-density polyethylene (LDPE) for flexibility and complete sample expulsion, they are supplied non-sterile in a 400/Bag bulk format ideal for high-throughput workflows. Part number 230-1565-020 covers a broad range of specimen transfer, reagent dispensing, and diagnostic support applications.

Frequently Asked Questions
Are these transfer pipets sterile?
No — they are supplied non-sterile. For applications requiring sterile transfer pipets, please contact us for sterile alternatives in the Caplugs® Evergreen line.
What does the 20 µL drop size mean in practice?
The fine tip is calibrated to deliver approximately 20 µL per drop under normal dispensing pressure. This provides a practical semi-quantitative reference for routine specimen transfer and reagent spotting, though it is not a substitute for calibrated micropipettor accuracy when precise volumes are required.
Is LDPE suitable for the reagents used in my lab?
LDPE offers broad compatibility with aqueous buffers, dilute acids and bases, and common alcohols such as methanol and isopropanol. Aromatic and chlorinated solvents should be verified against your specific reagent before routine use. Consult the chemical resistance table above or contact our technical team with specific reagent questions.
How are the pipets packaged, and is lot documentation available?
Each bag contains 400 pipets. Caplugs® Evergreen applies lot-level quality controls, so lot numbers are available for documentation in CAP-, CLIA-, and ISO 15189-accredited laboratories. Contact LabSupplies.com for lot-specific records when required by your quality system.
