It has a little rubber bulb at the center, a narrow tip and a hash mark that tells you when it is full. The bulb is used to create a vacuum of sorts that helps to suck air and then draw the liquid into the device. What is it used for? Pipettes are primarily used as media dispensers. What is the level of accuracy? Highly accurate. Their accuracy is partly dependent on their size which comes in a range of 12 to 24 inches. The graduations on a pipette can measure liquids within a 0.
On the whole, all the different glassware have a level of accuracy that works in specific cases. They key to chemistry experiments is to use high-quality products that are tolerable to the hazardous chemicals in use and provide accurate readings.

Wrong Temperature — Volumetric flasks are marked with volume, temperature, and accuracy readings. The T. This is followed by a temperature in celsius, and finally, the accuracy you can expect from the measurement. This might look like:. There are plenty of necessary things to consider when equipping a lab.
While pipettes may not seem like much on the outset, even these small expenses can add up to a big bite out of your budget. To cut your expenses and save money for all the small and not-so-small costs of setting up and running a lab, we offer a cost-effective solution to some of your biggest headaches.

Instruments for Measuring Volume Glassware used in lab settings come in a wide variety of sizes and shapes. Erlenmeyer Flasks These flasks have a narrow, cylindrical neck and a conical base with a flat bottom.
Florence Flasks With a long neck over a round bulb with a flat bottom, Florence flasks are also usually made of borosilicate glass to withstand heating. Beakers Beakers are cylindrical, glass containers with a rolled lip and spout for pouring. Graduated Cylinders Similar to beakers, graduated cylinders are tall, cylindrical containers with a spout for pouring. Volumetric Flasks Also called Dewar flasks after Scottish chemist and physicist Sir James Dewar, volumetric flasks have a long, narrow neck and a round bulb with a flat bottom.
Burettes Burettes are long, narrow glass tubes with hash marks for measurement along the side. They are applicable for various sectors like physical science, quality assurance, and engineering. Electrical, electronic and mechanical are different types of measuring instruments. Be it a time, length, size, speed, sound, light, weight, pressure or temperature measuring these parameters are the whole and sole part of our daily routine. From regular medical check-ups, measuring the weight of groceries, transportation to controlling the temperature while cooking are the common aspects where measuring instruments are essential.
So, start taking the correct measurements now by choosing the right type of measuring instruments online.

Vernier Caliper is a measuring and layout tool typically used for measuring linear dimensions. It can measure the outer dimension using the main jaw, inner dimensions…. A feeler gauge is one of the measuring and layout tools used for measuring the clearance between two parts.
It consists of several small lengths of…. Vernier calipers are measuring tools used mainly for measuring linear dimensions. These calipers come handy in measuring the diameter of circular objects. Their circular jaws fit…. Utilized in a wide variety of fields, calipers can be found in the offices of mechanical engineers, scientists, and doctors, as well as in the field with metalworkers, woodworkers, and forestry researchers. Used for both navigation and establishing orientation, it relies on the natural magnetic pull of the Earth to establish a relative direction for the user.
Especially useful on construction jobs, it is also a standard inclusion in woodworking and metalworking shops. An exceptionally diverse field of measurement tools, pressure gauges are used to quantify everything from altitude to air pressure to depth to blood pressure. Hydrostatic and aneroid gauges are the most common styles of an analog pressure gauge; the former has a delayed response but is great for sustained pressure, while the latter responds quickly but is less accurate overall.
A transparent plastic or glass half-circle, the protractor measures angles and is usually marked with degrees. They are a staple of the mechanical engineering profession but are also commonly found employed in high school geometry classes. Professionally, they are mostly found in engineering and construction jobs, where they are used to ensure accurate measurements on flat surfaces. A popular tool to have around the house, rulers are perhaps the most common measuring tool in use today.
Available in a variety of specialized forms, you may also find:. Combination squares, rulers with interchangeable angled heads that are used in woodworking and stonemasonry to mark out angled cuts.
Drywall squares, extra-large versions of the standard measuring square that are designed to allow long, accurate markings for drywall cuts. Framing squares, also known as steel squares. Widely used in carpentry to set up perfect right angles, the shorter side is known as the tongue while the longer side is known as the blade.
Tape Measure. Also known as a measuring tape , these flexible rulers can be used to take measurements of size or distance. Alternatively, the self-retracting metal tape measure utilizes a spring-loaded housing that can be clipped onto a belt.
A ubiquitous tool of the construction trades, these tape measures are especially useful for taking measurements over long distances — sometimes up to feet!
