5 mL Serological Pipette

5 mL Serological Pipette Blue 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 reducing contamination risk. The 5 mL size is the workhorse of daily cell culture workflows for routine media exchange, buffer addition, and reagent dispensing. Product Overview The 5 mL serological pipette – also commonly referred to as a 5 mL cell culture pipette or sterile 5 mL serological pipette – is a precision disposable pipette designed for aseptic liquid handling in cell culture, molecular biology, and clinical diagnostics where larger volumes (2-5 mL) are routinely transferred. 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 5 mL sterile disposable pipette (Cat# 21111003) meets ISO 12771, features a stretched tip for smooth flow, and is color-coded blue for easy size identification (standard for 5 mL). It is gamma irradiated (SAL 10-⁶), certified non-pyrogenic, DNase/RNase-free, and endotoxin-free. The larger inner diameter (Φ8.2 mm) provides fast liquid uptake, and the extended length (338 mm) improves media bottle access – you can reach the bottom of 250 mL or 500 mL bottles without tipping, reducing spill risk and simplifying sterile liquid transfer. Key advantage: Individual sterile packaging minimizes contamination exposure and waste – a critical upgrade from bulk-packed alternatives. The 5 mL format is the workhorse for routine media exchange, media preparation, buffer additions, and reagent dispensing where volumes exceed 2 mL but are below 10 mL. Why Labs Choose Individually Wrapped 5 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 5 mL capacity for routine media exchange -Faster than using multiple 1 mL or 2 mL pipettes; more precise than 10 mL for medium-large volumes (e.g., 5 mL media per T-25 flask, 5 mL per 6-well plate well). Superior media bottle access -The 338 mm length reaches deep into media bottles, centrifuge tubes, and large flasks without tipping or splashing, making daily cell culture tasks safer and faster. For cell therapy, vaccine production, and clinical diagnostics, individually wrapped serological pipettes are the standard over bulk-packed. The 5 mL cell culture pipette is especially popular for routine passage of adherent cells (e.g., adding 5 mL fresh media to T-75 flasks) and for transferring larger sample volumes in QC workflows. 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 5 mL serological pipettes. No adapters needed. The longer length (338 mm) is designed to reach the bottom of deep vessels while maintaining compatibility with standard pipettors. 4. 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. Extended length (338 mm) -Improves media bottle access; reduces the need to tilt large bottles during sterile liquid transfer, minimizing spill risk. Larger inner diameter (Φ8.2 mm) -Faster liquid uptake than smaller sizes, improving workflow efficiency for routine media transfer and daily cell culture tasks.

For every production lot, we provide Certificate of Analysis (COA), sterility certificate, and endotoxin test report upon request. Are the pipettes manufactured in cleanroom conditions? Yes. Hawach serological pipettes are manufactured and packaged in ISO-classified cleanroom environments to ensure sterility and particulate control. Can the packaging configuration be customized for distributors? Yes. We offer OEM services including custom pouch printing (logo, part number, instructions), private label cartons, and custom bag counts. Minimum order quantity applies. What is the graduation interval on the 5 mL pipette? Typically 0.1 mL increments from 0 to 5 mL, plus negative graduations for blow-out delivery. Exact interval available on COA. Is it compatible with electronic pipettors? Yes. Fits all standard 1-10 mL serological pipettors from Eppendorf, Thermo, Sartorius, Brand, Gilson, Rainin, and others. Why is the 5 mL size the most popular for routine media exchange? 5 mL is the most common volume for routine cell culture media changes (e.g., T-25 flasks, 6-well plates, 60 mm dishes). It offers faster work than using multiple 2 mL pipettes while being more convenient and less wasteful than 10 mL for medium-size transfers.
