What is glassware used for?
In any well-equipped lab, you’ll find a wide assortment of glassware designed to measure, pour, and hold liquids. This glassware comes in all shapes and sizes, from slender pipettes used to deliver small amounts of liquid to beakers that contain a much larger liquid volume.
Why do we use burettes in titration?
The stopcock can be turned to allow small amounts of liquid to flow out of the tube. Burettes are commonly used to measure precise, variable volumes of solution, primarily for titration, and mixing a known measurement of one reactant until the precise reaction is achieved.
How accurate are laboratory glassware markings?
The accuracy of the markings on laboratory glassware varies. Larger containers, like beakers and flasks, are typically ±5% of the total volume. They are generally used only when the volume measurement does not need to be precise. For graduated cylinders, the margin of error, or tolerance, is about 1%.
What is lab glassware made of?
Each device serves a specific purpose. Lab glassware, made from borosilicate glass, is strong and hard to break. It is suitable for containing chemical reactions and heating liquids to high temperatures.
What is a pipette used for?
Pipettes are measuring devices used to deliver liquids in tiny amounts. They are long, narrow glass tubes with tapered ends and a bulb in the center. They have a hash mark to indicate when they are full. Scientists use a small rubber bulb to draw liquid into the tube and transfer it to another container or mixture.
1. Ruler
A ruler is a long measuring instrument that is used to measure the length of an object. Generally, rulers are made of iron, mica or wood. This measuring instrument is commonly used by the community and is even considered a necessity for children at school. There are 10 cm- to 100 cm-length rulers. The most common length for a ruler is 30 cm.
2. Roll Meter
The roll meter is an instrument for measuring the length of an object. This tool is similar to a ruler, except that the roll meter has a longer measuring distance of up to 50 meters. This tool is used in the furniture industry to measure wood or planks for furniture.
3. Elbow Ruler
The elbow ruler is a measuring instrument used to measure the length as well as to ensure that the right angle is equal to 90o. In the picture, the elbow ruler can only check the 90o angle, but there is another form of the elbow ruler that has been equipped with an angle-adjusting feature so that it can be rotated to check the angle of the object.
4. Angle Ruler
This instrument is generally used by children at school to measure the angle of an object or to draw angles. Angle arcs are often found during math lessons and are used to solve math problems. Those who are still at school must have had carried or held this instrument.
5. Calipers
A caliper is an instrument used to measure the length, thickness, diameter, and depth of an object. It has a measurement accuracy of 0.1 mm. For example, if we want to measure glass with this tool, we will have the following results:
6. Micrometer
A micrometer is also used to measure the diameter and thickness of an object. However, this tool has a higher accuracy than calipers with an accuracy of 0.01 mm. Therefore a micrometer is used to measure the diameter and thickness of smaller objects, such as coins.
7. Scale
The scale is a measuring instrument used to measure the weight or mass of an object. There are various kinds of scales such as sitting scales, body scales, three-arm scales, digital scales, hanging scales, and others.
What are the instruments used to measure?
Instruments for Measurement: Measuring Instruments are used for measuring different things like weight, length, perimeter , area, time, temperature, volume and so on. We use different instruments such as weighing scales and balance to measure weight. We use various instruments such as a ruler, measuring tapes and metre stick to measure length or distance. Instruments such as thermometer are used to measure temperature. We use different instruments such as a calendar, watch, clock, stopwatch, and hourglass. A protractor is used to measure the angles.
What is measuring tape?
Measuring Tape – It is used to measure the length of an object.
What is analog weighing scale?
An analog weighing scale is the traditional and the simplest weighing scale. It is in usage for many years, and it is one such weighing machine that we still find in the majority. On the one hand, the analog weighing machines are easy to operate and do not require any battery or complex mechanism such as electronic chips. On the other hand, it comes at a relatively lower price than digital weighing machines.
How do we measure time?
We can measure time in terms of years, months, weeks, and days. We use a calendar to do this. It is done by giving names to periods, typically days, weeks, months, and years. A date is the designation of a single, specific day within such a system. A calendar is also a physical record (often paper) of such a system.
What is the space that liquid takes up?
When liquid is poured into a container, it takes up a certain space. The space it takes up is called its volume. We measure the volume of liquids by using a beaker.
What is a carpenter tape?
It is used for measuring the length of the physical object. Carpenters commonly use it in their lines of work. It is very convenient and portable and thus can be easily carried from one place to another. It usually comes with a handy switch that locks the tape into a steady position. And when you release it, the tape retracts back inside the casing instantly.
What is balance scale?

1. Common Scales
This type of scale is most often found in grocery shopping centers, such as markets or grocery stores. The way to use it is by placing the object to be measured on the scale. The scale or size of the sitting scale ranges from 1 kg to 500 kg. This scale has several weight capacities depending on its usage.
2. Manual Scales
Manual scales are also commonly found in markets or grocery stores. You could say that this type of scale is one that has been used for a long time and many people still use it, especially in traditional markets.
3. Body Scales
These scales are often found in health centers such as clinics, hospitals, health centers or pharmacies. But sometimes it is also owned by ordinary people to control their weight.
4. Ohaus Scales
The Ohaus balance is more commonly referred to as the Ohaus balance, in general it is also called the analytical balance. It is given this name, because this balance can measure the weight of an object with an accuracy of 0.01 grams and even up to 0.001 grams, depending on the brand of the scale.
5. Quartz Micro Scales
Just like Ohaus scales, quartz micro balances are also used in laboratory and science environments. This scale only has a measurement limit of 1 gram, but with very high accuracy, so it can measure very little gas weight.
6. Hanging Scales
As the name implies, these scales are used by hanging the object to be weighed on a hook that has been connected to the scale.
7. Digital Scales
As previously explained, digital scales display measurement results on the display screen. At first glance, the form of this scale is similar to a digital Ohaus balance, it’s just that the digital scales referred here can be used conventionally.
