What does multichannel pipette mean?
Multichannel pipettes generally come with either 8 or 12 pipette heads, easily allowing for a single device to fill multiple wells at a single time. This enables the user to quickly and easily fill multi-well plates used in tissue culture, drug screening, or enzyme assays.
What is Finntip?

Who makes finnpipette?
Thermo Fisher Scientific
This unique and incredible benefit is a promise from Thermo Fisher Scientific to provide the highest quality pipettes for it’s customers. 5-year warranty is provided to each registered customer, the non-registered pipette owners get automatically 3-year warranty.
How do you calibrate finnpipette?
Procedures to adjust the pipette: Place the service tool that comes with the pipette, into the openings of the calibration nut at the top of the handle. Turn the service tool clockwise to increase the volume or counterclockwise to decrease the volume. After the adjustment, check the calibration as described above.
What are pipetting techniques?
Pipetting technique is a term that is used to refer to the full scope of a user’s interactions with a pipette as they conduct their experiments. As would be expected, some practices are termed proper pipetting technique and help the user maintain a high level of accuracy and precision in their volume transfers.
What is Z factor in pipette calibration?
The calibration of pipette is carried out by gravimetric method. When determining the volume of water, the accuracy of measurements is effected by ambient temperature, atmospheric pressure and relative humidity. These factors are usually combined to give the Z factor, used in calculation of volume of water.
How do you find the accuracy and precision of a pipette?
The most common way to check your pipette accuracy is by weighing water. The density of water is 1 g/mL. This means that every microliter (µL) should weigh exactly 0.001 g using a high-precision balance.
How is Z factor calculated?
Z factor is calculated as the separation band divided by the dynamic range (i.e., the difference between the sample mean and the control mean), which is calculated as shown in Equation 1. The same equation can be expressed in Equation 2 when rearranged. Based on Z-factor value, the hits can be discerned.
What is CV in pipette calibration?
Standard deviation can be expressed as a relative value as cv. % CV (Coefficient of Variation) = (Standard Deviation / Corrected Mean) × 100. Calculate the average ( Mean ), accuracy, standard deviation (S.D.) and imprecision ( C.V. ) using the. following formula: n n － 2.
What is Z-factor in pipette calibration?
What types of laboratory pipettes does Labsystems offer?
It offers manual, electronic, and digital pipettes used in all types of laboratories around the world. The precise laboratory pipettes of Labsystems can be found in research and development, quality control, and production laboratories.
What is the performance of a pipette?
A pipette’s performance is directly related to the quality of the pipette tip for optimal liquid handling results.
How accurate is air displacement pipetting?
Air displacement pipetting is highly accurate for standard pipetting applications. However, conditions, such as atmospheric pressure as well as the specific gravity and viscosity of the solution, may effect the performance of air displacement pipettes.
What are electronic pipettes used for?
Electronic tip ejection, index finger pipetting action and ClipTip™ technology make these pipettes ideal for repetitive pipetting tasks. These adjustable tip spacing electronic pipettes allow you to transfers between virtually any tube, rack, microplate or horizontal gel box.
