Product Description

Sterile serological pipettes manufactured from the highest grade resins, bulk-packed loose in a bag for high-throughput workflows where individual wrapping is not required. Available in 1, 2, 5, 10, 25, 50, and 100 mL volumes, each pipette features clear bidirectional scale lines, a negative scale design for extra capacity, and 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
  • Bulk pack — loose in sterile bag — convenient point-of-use sterility for standard lab 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 — manufactured for 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 — heat sterilization will compromise both the aerosol barrier filter and pipette performance. 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
  • Do not use pipettes from damaged or previously opened bags
  • Open bag aseptically inside a biosafety cabinet — remove pipettes as needed
  • Single-use only — do not reuse between samples to prevent cross-contamination
  • Inspect pipette for damage or defects 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. Autoclaving will compromise the aerosol barrier filter and pipette accuracy.
Frequently Asked Questions
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.
What does bidirectional scale lines mean?
Bidirectional scale lines allow you to read volume accurately in both directions — whether you are aspirating (reading as the liquid rises) or dispensing (reading as the liquid falls). This makes it easy to confirm the exact volume during both filling and delivery steps without needing to reorient the pipette.
Are these pipettes compatible with my pipette controller?
These serological pipettes are designed to be compatible with standard pipette controllers and electronic pipette aids. The color-coded mouthpiece end fits most common controller brands. If you have a specialized controller, verify compatibility with the pipette tip diameter before use.
Are Certificates of Analysis available?
Yes — Certificates of Analysis (COA) are available upon request for all serological pipettes. Each lot is tested and certified RNase-, DNase-, DNA-, ATP-, and Pyrogen-free, manufactured under ISO 13485, and meets USP Class VI biocompatibility requirements.
