RBO RBO-100
Single Channel Variable Volume Micropipette
Volume Range 10-100 uL · Soft-Click Increments · Universal Tipcone
The 10 - 100 uL window covers some of the most-used pipetting workflows in molecular biology, microbiology, immunology, and biochemistry. The RBO-100 delivers it with RBO's high-quality spring plunger mechanism, soft-click increments to prevent accidental volume changes, and a universal tipcone for tip-supply flexibility.
Why The RBO-100?
Variable-volume pipetting at the 10 - 100 uL range demands two things conventional pipettes struggle to deliver simultaneously: precision across the full volume window, and ergonomics that survive long pipetting sessions. Cheap pipettes drift; rigid plungers cause RSI.
The RBO-100 addresses both concerns. 0.6% accuracy and 0.2% CV at the 100 uL nominal meets ISO 8655 requirements, while the high-quality spring mechanism with audible soft-click increments delivers smooth, snag-free volume changes. The large grippy handle and in-built streamlined tip ejector make plate-format work comfortable across full-shift use.
SOFT-CLICK INCREMENTS
RBO's plunger uses a high-quality spring mechanism with audible soft-click increments — preventing accidental volume changes during pipetting.
0.6% AT 100 uL
At full nominal volume, the RBO-100 delivers 0.6% accuracy and 0.2% 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.
"0.6% accuracy, 0.2% CV, soft-click volume increments." — RBO is Microlit's foundational precision micropipette platform — launched in 2014 and trusted by thousands of labs worldwide for molecular biology, immunology, and clinical workflows.
