Tween 20, 10% solution. Pipette + tip combination: choose an air displacement pipette and a standard or wide orifice tip. The use of a positive displacement pipette and tip is also advisable for pipetting Tween 20. For example, for a 20 - 200 vl pipette, the error limit is 2.0 vl for every selected volume.Pipets are slender tubes, typically 12 to 24 inches long. They may measure a predetermined volume such as 25.00 mL or 10.00 mL. They may also have graduations (these are called “Mohr” pipets) that allow odd and fractional volumes to be delivered. They are generally accurate to within 0.02 mL and are thus classified as volumetric glassware. proof vol. 2 . r .

Oct 08, 2020 · Standard preparation from stock VOC solution (200 mg/L) for the calibration curve is one of fundamental source to the uncertainty budget. The preparation of standards was done by using pipette (pip) (100 μL and 1000 μL) and volumetric flask (flask) (50 mL). Thus, the uncertainty calculation of standard preparation (Eq. Moto flashing tool 2019.
