Applications
- Aspirating and replacing cell culture media in flasks and multiwell plates
- Aliquoting reagents and serum into tubes and reservoirs
- Dispensing buffers during sample prep and dilution series
- Transferring supernatant after centrifugation steps
- Plating bacterial or mammalian suspensions under a biosafety hood
- Measured liquid handling in tissue culture and assay development
Chemical Resistance
| Reagent Class | Compatibility |
|---|---|
| Aqueous buffers | Excellent |
| Dilute acids | Good |
| Dilute bases | Good |
| Alcohols (ethanol, isopropanol) | Limited — brief contact only |
| Acetonitrile | Not recommended |
| Aromatic solvents | Not recommended |
| Chlorinated solvents | Not recommended |
Polystyrene resists aqueous media well; organic solvents may craze or attack the wall, so reserve these pipettes for water-based and short-contact work.

Frequently Asked Questions
How are these serological pipettes sterilized?
Each pipette is supplied sterile and individually wrapped, ready for use in a biosafety cabinet without further processing.
What does the color band indicate?
The band color identifies volume at a glance: yellow (1 mL), green (2 mL), blue (5 mL), orange (10 mL), red (25 mL), and black (50 mL).
Are these pipettes compatible with standard pipette controllers?
Yes. They feature a universal plugged top that fits common motorized and bulb-style pipette controllers and pipette aids.
Can I use them with organic solvents?
They are intended for aqueous media and buffers. Acetonitrile, aromatic and chlorinated solvents are not recommended, and alcohols should only contact the polystyrene briefly.
