200 µL PosiStop Low-Retention Pipette Tips, Sterile, Graduated — 1000 Tips Per Pack
Globe Scientific PosiStop 200 µL Pipette Tips deliver precise, reproducible aspiration for PCR setup, qPCR master-mix dispensing, and serial dilution workflows. Low-retention surface chemistry minimizes sample loss with viscous or low-volume reagents, while molded graduations help bench scientists confirm draw volume at a glance.

Frequently Asked Questions
What does the low-retention surface do?
The treated polypropylene surface reduces sample film and droplet adhesion inside the tip, improving recovery for viscous liquids, surfactant solutions, and small volumes where retained sample would otherwise skew results.
How many tips come in each pack?
All four formats supply 1000 tips per pack. The bulk bag holds 1000 loose tips, while the racked, GreenRack, and refill formats each contain 10 units of 96 tips.
What is the difference between the Racked and GreenRack formats?
Both present 96 sterile tips per rack across 10 racks. The GreenRack uses a reduced-plastic, sustainability-focused rack design, offering the same loading convenience with a lower packaging footprint.
Are these tips universal fit?
The 200 µL PosiStop tips are designed for broad compatibility with standard 200 µL-range micropipettes. Verify fit against your pipette model before high-throughput deployment.
