Wobble-not™ Serological Pipets, Bulk Packaged

Unlike standard serological pipets with uniform cylindrical plug ends, Wobble-not™ pipets feature a patented 2-tier stepped plug end. This design creates two distinct contact zones within your pipet controller's silicone nozzle, reducing the insertion force required while drastically increasing lateral stability. Paired with ultra-clear printed graduations and high-contrast color-coded stripes, these pipets deliver ±2% volumetric accuracy at full volume. Supplied in bulk re-sealable bags, they reduce plastic wrapping waste during high-volume workflows.

Key Functional Benefits:

• Patented 2-Tier Stepped Plug End: Creates dual contact zones inside any pipet controller's rubber nozzle for maximum lateral stability, eliminating wobble and preventing dripping
• Reduced Insertion Force: Inserts smoothly with lower effort compared to traditional cylindrical pipets, reducing wrist strain during repetitive liquid transfers
• High-Contrast Ultra-Clear Markings: Bold, easy-to-read ascending and descending volume graduations simplify liquid measurement and reverse-pipetting steps
• Integrated Aerosol Barrier Plug: High-density porous polypropylene filter prevents fluid over-aspiration and guards controller barrels against aerosol contamination
• Universal Controller Compatibility: Fully compatible with all major motorized pipet controllers (and pairs seamlessly with VistaLab ali-Q™ 2 controllers)
• Eco-Friendly Bulk Bags: Bulk packaged in re-sealable bags to speed up cabinet setup times and reduce single-use plastic wrap landfill waste
