ConductScience Serological Pipettes provide reliable liquid handling for cell culture applications requiring sterile, precise volume transfer. These 50mL polystyrene pipettes feature E-beam sterilization, ensuring sterility without heat damage to plastic components. Purple color coding facilitates volume identification during multi-pipette protocols.
The pipettes are manufactured DNase and RNase free, preventing enzymatic degradation of nucleic acids during cell culture work. Non-pyrogenic construction eliminates endotoxin contamination that could interfere with cell viability and experimental outcomes. Graduated markings enable accurate volume measurement for media preparation, cell suspension, and reagent transfer applications.
How It Works
Serological pipettes operate on gravitational flow principles, allowing controlled liquid dispensing through graduated volume markings. The pipette is filled to the desired volume mark using manual pipetting devices or automated pipettors, then liquid is dispensed by gravity flow or controlled pressure.
E-beam sterilization uses electron beam radiation to achieve sterility without thermal exposure, preserving the dimensional accuracy of polystyrene construction. The non-pyrogenic manufacturing process eliminates lipopolysaccharide endotoxins that could activate cellular immune responses. DNase and RNase free production prevents nucleic acid degradation during molecular biology applications.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Sterilization Method | E-beam sterilization | Gamma irradiation or ethylene oxide sterilization are common alternatives | E-beam sterilization provides sterility without chemical residues or thermal stress that could affect plastic properties. |
| Enzyme Contamination Control | DNase and RNase free construction | Standard pipettes may not guarantee nuclease-free manufacturing | Prevents enzymatic degradation of nucleic acids during molecular biology applications. |
| Endotoxin Control | Non-pyrogenic construction | Basic pipettes may not control endotoxin levels | Eliminates endotoxin contamination that could interfere with cell viability studies. |
| Volume Identification | Purple color coding | Clear or differently colored pipettes | Facilitates rapid volume identification and reduces protocol errors during multi-pipette procedures. |
These pipettes offer E-beam sterilization with DNase/RNase free and non-pyrogenic construction for critical cell culture applications. Purple color coding enhances workflow efficiency and reduces contamination risk in sterile environments.
Practical Tips
Store pipettes in original sterile packaging until use and avoid touching the sterile tip with gloves or surfaces.
Why: Maintains sterility assurance and prevents contamination of cell culture applications.
Use controlled aspiration speed when filling to prevent bubble formation and ensure accurate volume measurement.
Why: Air bubbles can compromise volume accuracy and interfere with precise reagent transfer.
Dispose of used pipettes in appropriate biohazard waste containers according to institutional guidelines.
Why: Prevents potential exposure to biological contaminants and ensures proper waste management.
Check expiration dates on sterile packaging before use in critical applications.
Why: Expired sterile packaging may not provide adequate sterility assurance for cell culture work.
Read volume measurements at eye level with meniscus bottom aligned to graduation marks.
Why: Ensures accurate volume measurement and reduces parallax error in liquid transfer procedures.
If liquid does not flow smoothly, check for blockages or ensure proper pipettor attachment.
Why: Obstructed flow can indicate contamination or mechanical issues affecting transfer accuracy.
