Here are some of our best practices for maximizing pipette accuracy. Best Practices for Pipetting Accuracy Follow these steps to ensure increased pipette accuracy in any laboratory setting:. Proper Pipetting Angles — Angles play a critical role in both maximizing pipette performance and minimizing user errors.
Pre-wetting — After installing a tip onto your pipette, aspirate the select volume of liquid and dispense it back into the source container.
This is pre-wetting and it helps achieve pipetting accuracy by allowing the second aspiration — the liquid you actually transfer to the receptacle — to be completely dispensed from the tip.
Aspiration Depth — During each aspiration step, it is critical to submerge your pipette tip no more than mm below the surface of the liquid to avoid adhesion of the liquid to the outside of the tip. Consistent Smooth Speed and Pressure — While aspirating and dispensing liquid, use a smooth controlled speed through to the first stop and through to the blowout. This helps pull the entire measured volume out of the tip.
Blowing out — As you dispense a liquid against the side of the receptacle, always depress the plunger past the first stop, all the way to the blowout. Change Tips — Pipettes and pipette tips are designed to work in harmony as part of a pipetting system for delivering liquids with accuracy and precision. Tips are designed for single use.
Re-using a tip for multiple transfers may cause accuracy to vary from one measurement to the next. Manage Temperature Transfer — Pipettes are very susceptible to thermal transfer from your hands. This warmth significantly affects the accuracy and precision of the instrument over time. For pipettes, the best practice is to hold the instrument only when you are using it. Looking at such reviews will help you to know whether the Glass Pipette you want to buy good or bad.
View Product. Bestseller No. Can be used again after being cleaned up. Apply for testing laboratories, chemistry, microbiology, liquids, scents etc. After drawing the liquid, the tip can not touch other objects, so as to avoid contamination of impurities.
Blue suction ball: made of high quality rubber, non-toxic and odorless. Glass droppers with high quality: the dropper is made of lead-free glass with corrosion resistance. Clear reading lines on the pipettes' wall: Number from from mouth to head.
Glass wall is printed with clear and precise scale, easy for you to measure the liquid. Can be used again after being cleaned up Multiple Use -Perfect for receiving and dispensing liquids. When adding the liquid, the dropper is just above the vertical. High quality:Pipettes are made of borosilicate glass,thick and durable. Environmental and reusable:Come with brushes and glass stir rods,the glass pipettes are environmental friendly and non-toxicIt is also reusable after clean up,and better than plastic pipette.
Clear reading line:Graduation is very precise, clear and professional, the calibration marks are easily readable. Multiple using ways:Large reservoir for receiving and dispensing liquids. Apply for testing laboratories, chemistry, microbiology, liquids, scents and more. Clear Graduated Lines - Glass wall is printed with clear and precise scale from No. Multiple Use - Perfect for receiving and dispensing liquids. Perfect for receiving and dispensing liquids Environmental friendly and reusable; can be easily rinsed clean Commonly used in chemistry, microbiology, bio-chemistry and medical fields for lab experiments and researches.
Most of our work is done with sterile pipettes and if so, the operations are done aseptically. When working with non-sterile pipettes it is a good idea to work aseptically anyway as a matter of routine in order to practice the technique. Note that this pipette has a scale that extends above zero to expand the calibrated capacity of the pipette. Thus, this is really an Mohr pipettes are another type of pipette.
Mohr pipettes are not 'blow-out' type, nor are the tips part of the measurement.
