2 mL Serological Pipette

2 mL Serological Pipette Green Color Code Stretched Tip Gamma Irradiated DNase/RNase-Free Endotoxin-Free Common Problems with Bulk-Packed Serological Pipettes Opened bags expose unused pipettes to airborne contaminants, moisture, and particulates Difficult aseptic transfer into biosafety cabinets -risk of touching non-sterile surfaces Higher waste in low-volume workflows -you must open many pipettes at once Increased risk of cross-contamination in GMP or cell therapy environments Hawach individually wrapped sterile serological pipettes solve these issues – open one at a time, keep the rest sealed, and transfer aseptically into laminar flow hoods significantly reduces contamination risk. Product Overview The 2 mL serological pipette is a precision disposable serological pipette designed for aseptic liquid handling in cell culture, molecular biology, and clinical diagnostics where a larger volume than 1 mL is needed but 5 mL may be excessive. Each pipette is individually wrapped in a sterile peel-pouch, allowing you to open only what you need – ideal for GMP-controlled workflows and busy biosafety cabinets. Hawach’s 2 mL sterile disposable pipette (Cat# 21111002) features a stretched tip for smooth flow, and is color-coded green for easy size identification. It is gamma irradiated (SAL 10⁻⁶), certified non-pyrogenic, DNase/RNase-free, and endotoxin-free. The slightly larger inner diameter (Φ6.5 mm) and same length (272 mm) as the 1 mL version provide faster liquid uptake while maintaining accuracy for medium-volume transfers. Key advantage: Individual sterile packaging reduces contamination risk and waste – a critical upgrade from bulk-packed alternatives. The 2 mL format fills the gap between 1 mL and 5 mL, offering improved efficiency for medium-volume tasks such as cell seeding, media preparation, and reagent additions in 6-well or 12-well plates. Why Labs Choose Individually Wrapped 2 mL Serological Pipettes Reduced contamination risk -Each pipette sealed until use. No exposure of unused pipettes to ambient air or bench surfaces. Better BSC workflow -Peel-open pouch enables aseptic transfer into laminar flow hoods without touching the pipette shaft. Lower waste -Open exactly the number needed. No leftover contaminated pipettes from opened bulk bags. GMP & QC ready -Individual packaging simplifies traceability and controlled-environment handling; lot numbers on every carton. Optimized 2 mL volume -Faster pipetting than 1 mL, more precise than 5 mL for medium liquid volumes (e.g., 1.5-2 mL additions). For cell therapy, vaccine production, and clinical diagnostics, individually wrapped serological pipettes are the standard over bulk-packed. The 2 mL size is especially useful for tube-to-plate transfers (e.g., 2 mL into 6-well plates) and medium-volume reagent dispensing. Universal Pipettor Compatibility Compatible with all major serological pipettors and electronic controllers: Brand Compatible? Eppendorf Yes Thermo Scientific Yes Sartorius Yes Brand Yes Gilson Yes Rainin Yes Other standard 1-10 mL controllers Yes Fits standard top diameter for 2 mL serological pipettes. No adapters needed. Comparison: Individually Wrapped vs. Bulk-Packed Feature Individually Wrapped (Hawach) Bulk–Packed Sterility after first opening High – each pipette sealed Medium – remaining pipettes exposed Aseptic transfer into BSC Easy – open pouch inside hood Difficult – must handle carefully Cross-contamination risk Low Higher Suitable for GMP / regulated labs Yes Limited Waste from unused pipettes None Some Cost per pipette Moderate (value for sterility) Lower (but higher indirect costs) Conclusion: For aseptic cell culture and regulated workflows, individually wrapped pipettes provide superior sterility assurance. Key Features Stretched tip -Smooth aspiration and dispensing, reduced surface tension. Certified purity -Non-pyrogenic, DNase-free, RNase-free, endotoxin-free (≤0.25 EU/mL). Suitable for PCR and RNA work. High clarity polystyrene -Easy meniscus reading. Negative graduations -Allows blow-out delivery. Gamma irradiated (SAL 10⁻⁶) -Ready to use, no autoclaving. Lot traceability -COA available per lot. Optimal 2 mL capacity -Larger than 1 mL for faster work, smaller than 5 mL for better precision in medium-volume transfers.
