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.
