Frequently Asked Questions
1. What is the difference between air-displacement and positive-displacement pipettes?
Air-displacement pipettes are ideal for standard aqueous solutions, while positive-displacement pipettes use a piston to directly contact the liquid, making them superior for handling viscous, volatile, or corrosive samples without contamination.
2. How often should laboratory pipettes be calibrated?
To maintain accuracy and precision, pipettes should typically be calibrated every 6 to 12 months, depending on the frequency of use and the stringency of your laboratory’s quality control protocols.
3. When should I use a bottle-top dispenser instead of a pipette?
Bottle-top dispensers are best for accurately dispensing larger volumes of reagents directly from a bottle, reducing the risk of spills and improving efficiency when repetitive dosing of the same liquid is required.
4. What types of laboratory pumps do you offer?
Our range includes peristaltic pumps for gentle fluid transfer, vacuum pumps for filtration and aspiration, and syringe pumps for high-precision, low-flow rate applications common in microfluidics.
5. Are the volumetric apparatus items certified for accuracy?
Yes, many of our volumetric glass and plastic items, such as measuring cylinders and volumetric flasks, come with batch or individual certificates of conformity to ensure they meet specific accuracy classes (Class A or Class B).
6. How do I know if a pipette tip is compatible with my pipette brand?
Answer: The most reliable method is to use a technical cross-reference guide. High-quality tips, such as the LLG Labware range, are engineered to create a secure, leak-proof seal with major brands like Eppendorf, Gilson, and Thermo Scientific. To verify the exact fit for your specific model, you can consult the full LLG Labware pipette tip compatibility table.
7. When should I use filter tips instead of standard tips?
Answer: Filter tips are essential for molecular biology, PCR, and handling sensitive samples where aerosol contamination must be avoided. These tips feature an internal barrier that protects both your pipette and your sample from cross-contamination. Learn more about selecting the right format in our guide on how to optimise your pipetting accuracy with compatible pipette tips.
8. What are the benefits of using low-retention pipette tips?
Answer: Low-retention tips are chemically treated or moulded to ensure that every microliter of liquid is expelled, which is critical for high-precision workflows. By minimizing sample residue on the inner walls, you improve reproducibility and reduce the loss of expensive reagents. Discover the technical benefits of low-retention tips for pipetting accuracy
9. Can using the wrong pipette tip cause measurement errors?
Answer: Yes, using incompatible or low-quality tips is a primary cause of measurement error and can compromise the airtight seal required for precision. Even the most advanced pipette is only as reliable as its tip. To safeguard your research, read our expert advice on how to choose the right pipette tip for your application
