100–1000 µL Two-Step Tiered Pipet Tips — PP, Blue, Non-Sterile, 1000/Bag (230-1467-B3K)
These 100–1000 µL polypropylene pipet tips feature a two-step tiered shaft design that delivers a secure, airtight seal and accurate volume delivery across the full working range. Supplied non-sterile in bulk 1000/Bag format, they are well suited to high-throughput clinical, research, and pharmaceutical pipetting workflows. The blue color coding follows the established large-volume tip convention, enabling fast visual identification at the bench.

Frequently Asked Questions
Are these tips sterile?
No — they are supplied non-sterile in 1000/Bag bulk packaging, which is appropriate for the vast majority of general bench, clinical chemistry, and molecular biology pipetting workflows that do not require sterility.
What makes the two-step tiered design different from a universal tip?
The two-step tiered shaft profile is engineered to match the specific tip-channel geometry of compatible pipettors, providing a secure mechanical seal and accurate volume delivery that a single-taper universal tip may not reliably achieve on these platforms.
Can polypropylene tips be autoclaved?
Polypropylene is generally autoclavable; however, these tips are supplied non-sterile and intended for single use. If autoclaving is required for a specific workflow, verify that your laboratory's autoclave cycle parameters are appropriate for the bulk bag format before processing.
What is the shelf life and storage requirement for these tips?
When stored in a clean, dry environment away from direct sunlight and harsh chemical vapors, polypropylene pipet tips maintain their dimensional stability and performance characteristics for an extended period. Refer to the lot documentation included with each bag for specific storage guidance.
