1.0 mL Disposable Transfer Pipets — Standard Tip, LDPE, Natural, 500/Bag (230-1563-020)
These 1.0 mL low-density polyethylene (LDPE) disposable transfer pipets feature a standard wide-bore tip and a calibrated 40 µL drop size, making them a practical choice for routine specimen transfer, reagent dispensing, and sample processing in clinical and research settings. Supplied non-sterile in bulk 500/Bag format, they are well suited to high-throughput laboratory workflows where single-use disposable pipets are consumed in large daily quantities. The inherent flexibility of LDPE ensures complete sample expulsion and minimal residual retention with every transfer.

Frequently Asked Questions
Are these transfer pipets sterile?
No — the 230-1563-020 is supplied non-sterile. For applications requiring sterile transfer pipets, look for the sterile-packaged variants in the Caplugs® Evergreen line.
What does the 40 µL drop size mean in practice?
The 40 µL/drop calibration provides a semi-quantitative volume reference useful for routine dispensing tasks where approximate delivery is acceptable. It is not a substitute for a calibrated micropipettor when precise volumetric accuracy is required.
Why choose LDPE over polypropylene for a transfer pipet?
LDPE is softer and more flexible than polypropylene, which makes it easier to squeeze the bulb fully and expel the entire sample — an advantage when working with viscous specimens or when minimizing residual volume matters.
How are these pipets packaged, and are they suitable for high-volume labs?
They are packaged 500 per bag in a bulk format designed for laboratories that process large daily specimen volumes and need a consistent, cost-effective disposable pipet supply on hand at all times.
