Product Description

Sterile serological pipettes manufactured from the highest grade resins, available in individually wrapped paper/plastic packaging or bulk-packed loose in a sterile bag — select the format that best matches your workflow. Available in 1, 2, 5, 10, 25, 50, and 100 mL volumes with color-coded rings for instant volume identification.

The built-in aerosol barrier filter — made from bonded polyolefin fiber — provides superior contamination protection compared to standard cotton plugs, effectively preventing cross-contamination and reducing the risk of over-pipetting and pipetting device contamination. The 1, 2, 5, and 10 mL pipettes are manufactured from a single piece of polystyrene plastic, eliminating the weld points found in many competing brands. Weld points can trap liquid and introduce inaccuracies — single-piece construction ensures clean, accurate, reproducible liquid delivery with every use.

Key Features & Benefits
  • Two packaging formats — individually wrapped paper/plastic for point-of-use sterility, or bulk-packed loose in a sterile bag for high-throughput workflows
  • Seven volume formats — 1, 2, 5, 10, 25, 50, and 100 mL to cover the full range of serological pipetting applications
  • Single-piece polystyrene construction — available for 1, 2, 5, and 10 mL — eliminates weld points that can trap liquid and cause inaccuracies in competing brands
  • Built-in aerosol barrier filter — bonded polyolefin fiber filter prevents cross-contamination and reduces over-pipetting risk — superior to standard cotton plugs
  • Clear bidirectional scale lines — accurate volume measurement in both aspiration and dispensing directions
  • Negative scale design — provides extra capacity beyond the nominal volume for complete liquid delivery
  • Color-coded rings — instant volume identification at a glance — reduces selection errors at the bench
  • Highest grade resins — consistent, reproducible performance across all volumes
  • RNase-, DNase-, DNA-, Pyrogen-, and ATP-free — certified for sensitive cell culture, molecular biology, and clinical applications
  • Sterile — gamma irradiated, dose verification per ISO 11137, SAL 10⁻⁶
⚠️ Not autoclavable — pipettes are pre-sterilized and certified ready to use from packaging.

Storage & Handling
  • Store in original packaging in a clean, dry environment away from direct sunlight and UV exposure
  • Maintain storage temperature between 15°C and 30°C (59°F – 86°F)
  • Keep away from excessive humidity
  • Individually wrapped: Do not use pipettes from damaged or previously opened packaging — peel open aseptically at point of use inside a biosafety cabinet
  • Bulk pack: Open bag aseptically inside a biosafety cabinet — remove pipettes as needed and reseal bag between uses
  • Single-use only — do not reuse between samples to prevent cross-contamination
  • Inspect pipette for damage before use
  • Dispose of used pipettes in accordance with your institution's biosafety waste disposal guidelines
⚠️ Not autoclavable — do not attempt to re-sterilize. Pipettes are pre-sterilized and certified contaminant-free from the factory.
Frequently Asked Questions
When should I choose individually wrapped vs bulk pack?
Individually wrapped pipettes are the preferred choice when point-of-use sterility is required — each pipette is sealed in its own paper/plastic peel pack and remains sterile until opened. This is ideal for standard cell culture, clinical, and sterile-critical workflows. Bulk pack pipettes are suitable for high-throughput workflows where the entire bag is opened and used within a single session inside a biosafety cabinet, reducing the time spent opening individual wrappers during rapid multi-pipette workflows.
What is the advantage of single-piece construction?
The 1, 2, 5, and 10 mL pipettes are manufactured from a single piece of polystyrene with no weld points. Some competing brands weld the pipette tip and mouthpiece to the main body — these weld points can trap liquid, introduce inaccuracies, and create potential contamination sites. Single-piece construction eliminates these risks for cleaner, more accurate, and more reproducible liquid delivery.
How does the aerosol barrier filter compare to a cotton plug?
The built-in bonded polyolefin fiber aerosol barrier filter provides more consistent protection than traditional cotton plugs. Cotton plugs can become wet, degrade over time, and provide variable filtration. The polyolefin fiber filter maintains a reliable barrier against aerosols and over-pipetting, protecting both your sample and your pipetting device from cross-contamination.
What does the negative scale design mean?
The negative scale design extends the graduation markings beyond the nominal volume of the pipette, providing extra capacity for complete liquid delivery. This ensures you can fully dispense the target volume without running dry at the tip — particularly useful for complete transfer of viscous samples or when working at the upper end of the pipette's capacity.
Are Certificates of Analysis available?
Yes — Certificates of Analysis (COA) are available upon request. Each lot is tested and certified RNase-, DNase-, DNA-, ATP-, and Pyrogen-free, manufactured under ISO 13485, and meets USP Class VI biocompatibility requirements. Contact us with your lot number for documentation.
