RBO RBO-F-5
Single Channel Fixed Volume Micropipette
Fixed 5 uL Dispense · Universal Tipcone · ISO 8655 Certified
Clinical diagnostics and control analysis labs run thousands of identical-volume dispenses every shift — and dial-in errors on variable-volume pipettes are a leading cause of QC drift. The RBO-F-5 eliminates that risk entirely with a fixed 5 uL dispense, soft-click plunger mechanism, and in-built streamlined tip ejector.
Why The RBO-F-5?
Fixed-volume pipetting solves a problem variable-volume pipettes don't: it eliminates volume-drift risk entirely. Clinical diagnostics, control analysis, and high-throughput plate fills all benefit from a pipette where the operator cannot accidentally change the dispense volume mid-shift.
The RBO-F-5 delivers fixed 5 uL dispenses with 2% accuracy and 1% CV at nominal, calibrated against DIN EN ISO 8655-2 at Microlit's NABL ISO 17025 lab. Combined with the universal tipcone and in-built tip ejector, the workflow ergonomics keep operators productive across long sessions.
SOFT-CLICK INCREMENTS
RBO's plunger uses a high-quality spring mechanism with audible soft-click increments — preventing accidental volume changes during pipetting.
2% AT NOMINAL
At 5 uL, the RBO-F-5 delivers 2% accuracy and 1% CV per the catalog spec, verified against DIN EN ISO 8655-2 at Microlit's NABL-accredited ISO 17025 lab.
UNIVERSAL TIP COMPATIBILITY
The universal tipcone accepts most internationally accepted standard tips — eliminating vendor lock-in and giving labs maximum tip-supply flexibility.
LARGE GRIPPY HANDLE
A specially designed large grip combined with the streamlined in-built tip ejector provides great ease of use during long pipetting sessions and comfortable access to bottles and tubes with narrow necks.
"Fixed 5 uL, 2% accuracy, soft-click plunger increments." — The RBO-F-5 is RBO's foundational fixed-volume model for clinical diagnostics and control analysis labs — workflow consistency without dial-in error risk.
