Applications
- Reagent and buffer aliquoting at a single locked volume
- PCR and qPCR master-mix dispensing for consistent reaction setup
- Serial dilution steps requiring fixed transfer volumes
- ELISA and microplate loading where operator-to-operator variance must be minimized
- Routine QC dispensing on high-throughput benches
- Dedicated-volume stations to prevent cross-contamination between protocols
Quality & Procurement
Shipped from US inventory through labsupplies.com, an authorized Globe Scientific dealer. Each unit carries lot numbers supporting traceability for CAP-, CLIA-, and ISO 15189-accredited laboratories. Institutional and grant-funded tiered pricing is available on request for multi-unit and standardized bench buildouts.
Frequently Asked Questions
Are these pipettes fully autoclavable?
Yes. The entire Diamond PosiStop unit is rated for full autoclaving at standard cycle parameters, allowing sterilization without disassembly between protocols.
Why choose a fixed-volume pipette over an adjustable model?
Fixed-volume pipettes lock to one calibrated setting, removing dial-misadjustment errors. For repetitive transfers at a known volume, they improve reproducibility and reduce QC failures.
What do the colors indicate?
Color denotes the working range: red covers 2.5–25 µL, green covers 50–200 µL, and blue covers 250–1000 µL, simplifying station organization at the bench.
What is the unit of sale?
Each SKU is sold individually (each) at $165.00 per pipette. Order the specific volume you need by its corresponding SKU.
