The OMNIS Titrator is a modular, highly precise titration system offering unparalleled flexibility and safety. It features digital sensors for accurate, faster analyses, a patented contact-free reagent exchange system, and supports multiple titration methods. Expandable with additional modules for parallel operations, it ensures adaptability to evolving lab needs while enhancing efficiency and minimizing user error.
(This is the suggested replacement for 3371) Feature uniform skirt heights for greater robotic gripping surface Solvent resistant polypropylene provides compatibility with many common organic solvents (e.g., DMSO, ethanol, methanol) Certified DNase- and RNase-free Total volume is 360 µL; recommended working well volume is 75 to 200 µL Without lids; lids, sealing mats and tapes supplied separately
An ergonomically contoured handle assures comfort and fatigue-free operation. Multi-point, color-coding for easy volume identification. Entire pipette is autoclavable without the need for recalibration. Curved hilt cradles your hand, allows a relaxed hand hold, and provides finer control while pipetting. Separate tip ejector button reduces hand motion and the curved shape enhances comfort.
