🔬 Premium Design Features
✅ Bidirectional Graduations - Read from Top or Bottom
Our serological pipettes feature ascending and descending graduations printed in bold, easy-to-read numbers. This dual-scale design allows you to:
- Measure dispensed volume - Read descending scale (TD - To Deliver)
- Measure remaining volume - Read ascending scale from tip
- Reduce calculation errors - Choose most convenient reading direction
- Improve efficiency - No mental math required for partial volumes
✅ Negative Graduation Zone - Accurate "To Deliver" Marking
Each pipette includes a negative graduation zone below the zero mark, ensuring complete liquid delivery when emptying to the last drop. This is critical for:
- Accurate cell culture media transfer
- Precise reagent dispensing in assays
- Standardization across experiments
- Meeting pharmaceutical manufacturing tolerances
✅ Large-Bore Opening - Fast Flow Rate
The wide tip opening facilitates rapid liquid uptake and dispensing, making these pipettes ideal for:
- High-throughput applications
- Viscous solutions (serum, glycerol stocks)
- Media containing particulates

✅ Cotton Plug Filter - Prevents Cross-Contamination
Each pipette features a built-in hydrophobic cotton plug in the mouthpiece that:
- Prevents liquid from entering pipette controller or pipettor
- Blocks aerosol contamination
- Protects expensive pipetting devices from damage
- Maintains sterility throughout use
- Meets biosafety requirements for hazardous materials
✅ Color-Coded Bands - Quick Size Identification
Universal color coding system matches industry standards:
- 🔵 Blue - 1mL
- 🟢 Green - 2mL
- 🟡 Yellow - 5mL
- 🟠 Orange - 10mL
- 🔴 Red - 25mL
- 🟣 Purple - 50mL
✅ Crystal-Clear Polystyrene - Excellent Visibility
Medical-grade transparent polystyrene construction provides:
- Easy visual inspection of liquid level
- Detection of air bubbles
- Verification of complete liquid transfer
- Enhanced accuracy through clear graduation visibility

💡 How to Choose the Right Pipette Size
| Pipette Size | Best For | Typical Applications |
|---|---|---|
| 1mL | Small volumes, precise work | Microcentrifuge tube work, small-scale transfections, adding concentrated reagents |
| 2mL | 96-well plates, small flasks | Filling 96-well plates, small T-flask work, reagent addition to tubes |
| 5mL | T25 flasks, 24-well plates | Most common size for routine cell culture, media changes in T25 flasks |
| 10mL | T75 flasks, 6-well plates | Standard cell culture work, media changes in T75 flasks, sample pooling |
| 25mL | T175 flasks, large volumes | Large flask media changes, buffer preparation, bulk reagent dispensing |
| 50mL | T225 flasks, bottles | Large-scale cell culture, media bottle filling, high-volume transfers |
💡 Pro Tip: For best accuracy, choose a pipette size where your target volume falls in the middle 50-80% of the pipette's range. For example, use a 10mL pipette for 5-8mL volumes rather than a 25mL pipette.
🔧 Usage Guidelines & Best Practices
Proper Pipetting Technique
-
Attach to Controller:
- Remove pipette from wrapper using aseptic technique
- Insert firmly into pipette controller or manual pump
- Ensure secure fit to prevent leakage or detachment
-
Aspirate Liquid:
- Submerge tip 2-5mm below liquid surface
- Aspirate slowly to avoid bubble formation
- Keep pipette vertical (perpendicular to bench)
- Do not allow liquid to reach the cotton plug filter
-
Dispense Liquid:
- Touch tip to vessel wall at 30-45° angle
- Dispense slowly and smoothly
- Allow final drops to drain naturally (3-5 seconds)
- For "blow-out" pipettes, expel final drop using controller
-
Disposal:
- Discard in appropriate biohazard or sharps container
- Never reuse single-use pipettes
- Follow institutional biosafety guidelines
Common Mistakes to Avoid
- ❌ Aspirating too fast - Causes bubbles and inaccurate volumes
- ❌ Touching pipette tip to non-sterile surfaces - Compromises sterility
- ❌ Overfilling past the cotton plug - Contaminates pipette controller
- ❌ Holding pipette horizontally while filled - Liquid may reach filter
- ❌ Not allowing drainage time - Results in inaccurate delivered volume
- ❌ Using wrong size for volume - Reduces accuracy
Maintenance of Pipette Controllers
To protect your pipetting equipment when using serological pipettes:
- Regularly check and replace controller filters
- Never invert controller with pipette attached
- Clean exterior with 70% ethanol regularly
- If liquid enters controller, decontaminate immediately per manufacturer instructions
- UV decontaminate controller between uses with hazardous materials
