2 mL Serological Pipette
Description
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.

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.
