Frequently Asked Questions
Are these PosiStop tips certified free of DNase, RNase, and pyrogens?
Globe Scientific manufactures these tips for molecular biology use with low-retention polypropylene and a barrier filter. Confirm specific purity certifications against the current product documentation before validating critical workflows.
How many tips come in each pack?
Each option supplies 1000 tips: the bulk bag holds 1000 loose tips, while the racked and GreenRack formats provide 96 tips per rack across 10 racks per box.
What is the difference between the racked and GreenRack options?
Both deliver 96 sterile tips per rack across 10 racks. The GreenRack format uses a reduced-plastic rack design to lower packaging waste, offered at a slightly lower per-pack price.
Why choose low-retention tips for 200 µL pipetting?
Low-retention surfaces reduce liquid adhesion to the tip wall, improving recovery of viscous, surfactant-containing, or high-value samples and tightening pipetting precision.
