Do you know how to use a pipette? These tips on how to pipette will instantly improve your pipetting technique and help you to correctly use a micropipette.
Why is a pipette accurate? Why are Volumetric pipettes more accurate? volumetric pipet more accurate because its long size decreases error of misreading the meniscus and volumetric pipets are designed to measure specific volumes (such as 5ml). Also graduated cylinders are not calibrated during manufa...
Why is the burette more versatile than a pipette for measuring volumes of liquids? Calculate the number of water molecules in a drop of water (drops of water = 1.00 g/mL; 1 drop = 0.0018 mL). Which one gives the least accurate measuremen...
Small volumes (50-100 mL) can be washed down the sink. Large volumes should be collected as hazardous waste. Note: if step 5 is necessary, add a small amount of the piranha solution to the waste container and inspect for any reaction. If there is no reaction, continue to pour the rema...
4. Pipette and Tips: Precision pipettes and their corresponding tips are used for accurate measurement and transfer of liquids, particularly small volumes, during the preparation of standard solutions and samples. Ensure pipettes are calibrated to avoid errors in solution preparation. 5. Volumetric Flas...
The dilution factor is used to calculate the number of cells in the original cell culture. In our example, an average of 50 colonies was counted on the plates obtained from the 1:10,000 dilution. Because only 0.1 mL of suspension was pipetted on the plate, the multiplier required to reco...
How many grams of solid potassium iodide (Kl) would be needed to prepare 250 mL of a 0.300 M solution? A corrosion technologist pipetted a 100.00 mL hard water sample and titrated it with 37.64 mL of 0.01 M EDTA solution for a total ...
(i.e., near the melting temperature) due to the release of latent heat. The emissivity coefficient of ice was calibrated atε = 0.98. Time zero corresponds to the bubble’s first contact with the icy substrate, where the top of the bubble is still adhered to the pipette (first ...
Pipettes, like the ones used in science class, are necessary to get the right amount of nicotine and flavors into the mix. They are easy to use, cheap and are able to be accurate down to the drip. Having one pipette for each flavor bottle without a built in drip will prevent any flav...
In her right hand, the technician in the photograph below holds an automated pipettor which is attached to a pipette. An automated pipettor—the device in the technician's right hand—is used to move fluids into and out of a pipette (the long glass tube). Automated pipettors can use encod...
