Nov 23, 2010 · Place some liquid in a graduated cylinder and look at the meniscus (where the liquid meets the air). Notice that the meniscus is bent such that the edges are higher than the centre. To get an accurate measure of volume, read the middle (lowest point) of the meniscus.The meniscus is the curve at a liquid’s surface by which one measures the volume of a liquid. 6. Why is it important to read the meniscus at eye level while the graduated cylinder is on a flat surface? It is important to read the meniscus at eye level while the graduated cylinder is on a flat surface to get an accurate; not distorted reading. 7.
Part I: The Graduated Cylinder. Determine the volume contained in a graduated cylinder by reading the bottom of the meniscus at eye level. Read the volume using all certain digits and one uncertain digit. Certain digits are determined from the calibration marks on the cylinder. The uncertain digit (the last digit of the reading) is estimated.

Encouraging results were reported by Jung and colleagues in a study on 13 patients affected by medial meniscus posterior root tear and treated with all-inside repair using 1 suture anchor, with 50% rate (5 out of 10 patients) of complete healing at the MRI control. 44 Concerning the lateral meniscus, Shelbourne et al. 45 showed that prognosis ... You should observe the container from the eye level, and if you see the liquid slightly above or below, you may find a little shift in the meniscus and get inaccurate readings. Once you have located the correct meniscus line, holding the measuring container at eye level, add or remove the liquid, till you have the desired volume in the container.
A. Using a Graduated Cylinder to Determine the Density of Water 1. Weigh to 0.01 g a clean, dry 10 mL graduated cylinder and record the value. 2. Add to the cylinder between 7.5 and 9.0 mL of water. 3. Read and record the volume to 0.1 mL. 4. Weigh the cylinder plus water, and record the value. 5. From your data, calculate the density of water. 6. Hold the cylinder at eye level to take a reading. Ensure that it is hanging straight down. Avoid crouching to read the cylinder while it is resting on the table; if jostled, the container could tip over and pour liquid onto your face or torso. Take the liquid measurement at the very bottom of the dip in the surface of the liquid. To get a measurement using a graduated cylinder, scientists look at the meniscus of the liquid and observe the lowest portion. Compared to the beakers and flasks that scientists use in a laboratory, these cylinders are usually more accurate for measuring the volume of a liquid.
A graduated cylinder is used to measure the volume of liquids. The curved surface of the water inside the cylinder is called a meniscus. Read the volume at the bottom of the curve of the meniscus, with your eye level at the surface of the liquid. 1.

This curved surface is called a meniscus and is caused by an interaction between the water molecules and the molecules of the glass container wall. When reading the volume of a liquid that makes a meniscus, hold the gradated cylinder so that the meniscus is at eye level, and read the liquid level at the bottom of the curved surface (that is, READING the BURET Remember the numbers start at 0.00 on top and go to 25.00 on the bottom The curved surface at the top of the liquid level is called a. meniscus. You read the liquid level using the bottom of the meniscus. The meniscus is created by surface tension of the liquid and the extent thatthe liquid "wets" the wall. If you're having trouble using burettes you can use a graduated cylinder in order to more easily read the amount of liquid being measured. The marks on the cylinder are also generally considered easier to read. There are a variety of different sizes of graduated cylinders. The most typical sizes are 10ml, 25ml, 100ml, 500ml, and all the way up ...
walls of the cylinder, a reading can be made. Note that a meniscus forms on the neck of the hydrometer. Just as reading the meniscus in a graduated cylinder, the user must take the reading where the plane of water is and not where the water clings up the neck of the hydrometer.

Meniscus is the curve in the upper surface of a liquid close to a container. The reading should be read as something like: SG 1.030, and not shortened to SG 30 as this may cause confusion later on. Always thoroughly clean up your hydrometer, measuring cylinder and any other containers used. Another example is measuring volume by reading a meniscus (parallax). You likely read a meniscus exactly the same way each time, but it’s never perfectly correct. Another person taking the reading may take the same reading, but view the meniscus from a different angle, thus getting a different result.

Jun 06, 2017 · The long answer: To read a meniscus, you first need to see what type of meniscus your liquid forms. If the meniscus is a concave meniscus, read at the lowest level of the curve. If the meniscus is convex, take your measurement at the highest point of the curve. The short answer: Take your measurement from the center of the meniscus. It’s that easy. • Show students the way to read a meniscus. • Explain to students the difference in accuracy between the graduated cylinder (read to ±1% of the total volume) and the pipet (read to the nearest ±0.02 mL), and the resulting difference in significant figures in measurements. • Remind students about proper disposal of broken glass.
