4. Products that are catalog #s 5090-xxxx are “Paper/plastic individually wrapped, sterile, RNase/DNase free” and shorter in length for better mobility and accuracy.

The Difference Is Crystal Clear! Wobble-not serological pipets are superior in ergonomics and performance compared to every other serological pipet.

See the Difference

Traditional serological pipets have a straight cylindrical shape vs. the Wobble-not, which have a two-tiered step design which helps to decrease insertion force, while increasing pipet stability in your controller.

Feel the Difference

You will feel better and work smarter. No more jamming your serological pipet into your pipet controller. Achieve maximum stability (no wobble) and LESS DRIPPING with our newest revolutionary design to benefit your health and wellness, as well as your research applications.

Wobble-not
The First Ever Ergonomic Serological Pipet!

With standard serological pipets, there has never been a difference in the plug end design. All require high insertion force (jamming) in an attempt to get the top as high up in the pipet controller nozzle as possible. You do this to try to get as much stability as possible otherwise, you risk dripping of the liquid you pipette. No matter how hard you jam, there is wobble.

Ergonomics and Performance in a never-before-seen design

Wobble-not serological pipets are a revolutionary, new design and the only serological pipets that will give you two zones of contact with relatively low insertion force. No jamming! And furthermore, this results in maximum stability for your pipetting and LESS DRIP! No other serological pipet comes close to achieving the same amount of Wobble-not!

Oxford Lab Serological Pipets

Oxford Lab Products Serological Pipets are precision-engineered for accuracy, safety, and universal compatibility. Each pipet is made from USP Class VI–compliant polystyrene with polyolefin filters that prevent liquid contamination and overflow. The gamma-irradiated, sterile packaging ensures clean, ready-to-use performance for tissue culture, clinical, and research applications.

Graduations are calibrated within ±2%, offering exceptional accuracy for both aspiration and dispensing. With reverse and negative graduations, clear black markings, and color-coded identification, Oxford Serological Pipets deliver exceptional usability and reproducibility across every workflow.

Key Features

• Universal Compatibility: Fits all standard motorized pipet controllers in the industry.
• Accurate Volume Control: Reverse and negative graduations ensure precise aspiration and dispensing, calibrated within ±2% accuracy.
• High-Quality Materials:
• Pipet: Made from crystal-clear GPPS (General Purpose Polystyrene).
• Filter: Made from PO (Polyolefin) for reliable liquid barrier protection.
• Sterile and Ready to Use: Individually wrapped in peel-to-open packaging to maintain sterility and prevent contamination.
• Filter Protection: Integrated filter barrier prevents liquid overflow into the pipet controller.
• Durable Temperature Range: Performs reliably between –20°C to +50°C.
• Color-Coded Identification: Distinct color bands allow quick and easy size recognition.
• Clear, Legible Graduations: Black printed markings for high visibility and effortless volume estimation.
• Certified Safe and Compliant: Free from DNase, RNase, pyrogens, cytotoxins, and latex.
• Quality Manufacturing: Produced under ISO 13485 and ISO 9001 quality management systems.
• Long Shelf Life: Stable for 3 years after production date.

Quality Assurance

Oxford Serological Pipets are manufactured in cleanroom environments under strict ISO-certified quality control standards. Each pipet is gamma-irradiated to SAL10 (ISO11137) and tested to ensure sterility, safety, and biocompatibility. Materials are USP Class VI compliant, guaranteeing they are safe for biological and clinical use.

Globe Scientific's plastic serological pipets are produced under the strictest protocols and offer the highest degree of accuracy.

The pipettes are supplied with an aerosol barrier plug that prevents both liquid and aerosols from contaminating the pipettors.

The serological pipettes are produced from crystal clear polystyrene (PS) and are color coded for easy volume identification.
