RBO RBO-E-200
8-Channel Variable Volume Micropipette
8-Channel Multi-Channel · 20-200 uL · Universal Tipcone
Multi-channel plate workflows demand consistency every 8 channels can sustain across the row. The RBO-E-200 brings RBO's spring-mechanism plunger and universal tipcone to 8-channel format, holding 0.8% accuracy and 0.3% CV at the 200 uL nominal across the full row.
Why The RBO-E-200?
In ELISA, qPCR plate setup, and clinical screening, channel-to-channel volume variability is the single largest source of intra-plate CV. The operator's thumb controls all 8 plungers, and force distributes unevenly across the row — unless the plunger mechanism is built for consistency.
The RBO-E-200 extends RBO's single-channel precision platform to multi-channel work. The high-quality spring plunger delivers consistent force distribution across all 8 channels, while the in-built streamlined tip ejector simplifies tip removal between transfers. The pipette fills 8 wells of a 96-well plate column in one stroke.
SOFT-CLICK INCREMENTS
RBO's plunger uses a high-quality spring mechanism with audible soft-click increments — preventing accidental volume changes during pipetting.
0.8% AT 200 uL
At full volume, the RBO-E-200 delivers 0.8% accuracy and 0.3% CV per the catalog spec across all 8 channels, verified at Microlit's ISO 17025 NABL 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.
"8 channels, soft-click increments, 0.8% accuracy at 200 uL." — The RBO-E-200 brings RBO's foundational pipette ergonomics to multi-channel plate work — the precision platform extended across an entire plate row in a single stroke.
