Sartorius Pipette Tips 1200 ul SafetySpace Sterile 7 Racks of 96 Tips Each

Sartorius 791211F SafetySpace Filter Tips – 1200 µL, Sterile, Racked

The Sartorius 791211F is a premium 1200 µL (1.2 mL) filtered pipette tip engineered for maximum sample security and precision. Part of the innovative SafetySpace series, these tips feature a unique design that leaves significantly more air space between the drawn liquid and the polyethylene filter barrier than conventional tips. This extra volume completely eliminates the risk of expensive or contagious samples permeating the filter, even when utilizing reverse pipetting or handling highly foaming biological liquids. Molded from premium virgin polypropylene in an ISO 8 cleanroom environment, the 791211F is E-beam pre-sterilized and certified free of DNase, RNase, human DNA, and endotoxins, making it an essential consumable for rigorous molecular biology and cell culture applications.

Technical Performance and Design

• SafetySpace Air Gap: The extended internal volume creates a physical buffer zone that prevents liquid from touching the filter during aggressive pipetting, securing 100% sample recovery and preventing costly cross-contamination.

• High-Purity PE Filter: The internal polyethylene filter barrier traps aerosols and vapors without utilizing "self-sealing" chemical additives, ensuring that no unwanted leachables interfere with your delicate analytical results.

• Virgin Polypropylene Construction: Molded from highly inert, colorless polypropylene to minimize fluid retention and ensure complete compatibility with organic solvents, mild acids, and biological buffers.

• Ergonomic Optiload Compatibility: While universally compatible with most major pipette brands, they are perfectly matched for the spring-loaded Optiload mechanism of Sartorius pipettes, ensuring a perfect seal with minimal attachment and ejection force.

Key Benefits & Applications

• Foaming Liquids & Solvents: The SafetySpace design is the gold standard for pipetting buffers, proteins, and viscous solutions that tend to bubble or splash upward into standard filters.

• Electronic Multi-Dispensing: Provides the necessary headroom to safely over-draw liquid for the multi-dispensing modes commonly used on motorized electronic pipettes.

• Molecular Biology: The strict certified purity profile and sterile packaging guarantee zero interference during sensitive PCR, qPCR, and genomic extractions.

• Zero Filter Interference: Because the filter contains no sealing additives, researchers do not have to worry about chemical contamination if an accident were to occur.
