Diamond PosiStop 12-Channel Adjustable Pipettes, Fully Autoclavable, 0.5–300 µL — Sold Each

The Globe Scientific Diamond PosiStop 12-Channel Pipette delivers parallel, reproducible dispensing across 96-well plates for high-throughput workflows. Built for ELISA assays, PCR and qPCR plate setup, and serial dilutions, each model pairs adjustable volume control with a positive-stop mechanism for confident, repeatable aspiration. Six color-coded ranges cover routine bench needs from sub-microliter additions to 300 µL transfers.

Frequently Asked Questions

Are these pipettes fully autoclavable?

Yes. Every model in the Diamond PosiStop 12-channel line is fully autoclavable, allowing complete sterilization of the instrument for contamination-sensitive workflows.

What does the PosiStop mechanism do?

PosiStop provides a defined positive stop during volume adjustment and aspiration, giving consistent, tactile feedback that improves repeatability across all 12 channels.

Do the channels fit standard 96-well plates?

They do. Fixed 9 mm channel spacing aligns with standard SBS 96-well microplate well pitch for accurate row-by-row dispensing.

How should I choose between overlapping volume ranges?

Select the model whose range centers on your target volume; accuracy is highest in the mid-to-upper portion. For example, dispense 50 µL with the 5–50 µL or 10–100 µL model rather than near a range limit.
