Title: 200 ml Beaker: A Versatile Laboratory Tool

A 200 ml beaker is a common laboratory tool used in various scientific disciplines. Its compact size and versatility make it an essential piece of equipment in many experiments and procedures. This article aims to shed light on the uses, properties, and precautions associated with a 200 ml beaker.

The primary purpose of a 200 ml beaker is to hold and mix liquids. Its wide mouth and cylindrical shape facilitate easy pouring and stirring. It is commonly used for measuring and transferring small volumes of liquids, especially in chemistry experiments. The graduated markings on the side of the beaker allow for accurate measurements, making it a reliable tool for quantitative analysis.

The material used to make a 200 ml beaker is typically borosilicate glass. This type of glass is resistant to thermal shock, making it suitable for heating and cooling substances. However, it is important to note that extreme temperature changes should be avoided to prevent breakage. Additionally, a 200 ml beaker is usually equipped with a spout to facilitate precise pouring without spillage.

Apart from holding and mixing liquids, a 200 ml beaker can also be used for simple reactions, such as acid-base titrations. Its wide base provides stability, preventing accidental tipping during experiments. Furthermore, the beaker can be easily covered with a watch glass or a small beaker cover to prevent contamination or evaporation.

When using a 200 ml beaker, certain precautions should be taken. Firstly, it is essential to handle the beaker with caution to avoid breakage. Secondly, the beaker should be placed on a heat-resistant mat or a tripod when heating with a Bunsen burner or any other heat source. Additionally, it is crucial to wear appropriate personal protective equipment, such as gloves and goggles, to ensure safety during experiments.

In conclusion, a 200 ml beaker is a versatile laboratory tool commonly used for holding, mixing, and transferring liquids. Its compact size, graduated markings, and stability make it ideal for various scientific applications. However, proper handling and safety precautions should be followed to ensure efficient and safe use. With its numerous applications and user-friendly design, the 200 ml beaker remains an indispensable tool in laboratories worldwide.

200 ml beaker uncertainty

A 200 ml beaker is a common laboratory tool used for measuring and transferring liquid volumes. Like any measuring instrument, it has a certain level of uncertainty associated with its measurements. The uncertainty of a 200 ml beaker can be influenced by various factors, including its manufacturing quality, calibration, and usage conditions.

Manufacturing quality plays a crucial role in determining the uncertainty of a 200 ml beaker. Beakers produced by reputable manufacturers tend to have lower uncertainties due to their adherence to quality control standards. On the other hand, beakers manufactured by less reliable sources may have higher uncertainties, as their volume markings may not be accurate or consistent.

Calibration is another important factor affecting the uncertainty of a 200 ml beaker. Regular calibration ensures that the beaker’s volume markings correspond to the actual volume of liquid it holds. If a beaker is not calibrated or if it undergoes wear and tear over time, its uncertainty may increase. Therefore, it is essential to calibrate the beaker periodically to maintain its accuracy.

The conditions under which the beaker is used can also impact its uncertainty. Factors such as temperature, pressure, and the skill of the operator can introduce additional sources of uncertainty. For instance, temperature variations can cause the beaker’s material to expand or contract, affecting its volume measurements. Similarly, an inexperienced operator may not correctly read the meniscus, leading to inaccurate volume readings.

To minimize the uncertainty associated with a 200 ml beaker, several steps can be taken. First, it is advisable to purchase beakers from reputable manufacturers known for their quality and accuracy. Regular calibration using traceable standards should be performed to ensure accurate volume measurements. Additionally, operators should be trained to use the beaker correctly and read the meniscus accurately.

In conclusion, a 200 ml beaker has an inherent level of uncertainty in its volume measurements. This uncertainty can be influenced by factors such as manufacturing quality, calibration, and usage conditions. By selecting high-quality beakers, performing regular calibrations, and training operators, the uncertainty associated with a 200 ml beaker can be minimized, leading to more accurate and reliable volume measurements.

200 ml beaker dimensions

A 200 ml beaker is a common laboratory tool used for various purposes such as measuring, mixing, and heating liquids. It is important to know the dimensions of the beaker to ensure accurate measurements and safe handling.

The dimensions of a 200 ml beaker typically include the height, diameter, and thickness of the glass. The height of the beaker can vary but is usually around 8-10 cm (3-4 inches). The diameter, which is the width of the opening, is typically around 6-7 cm (2-3 inches). The thickness of the glass can vary, but it is usually around 1-2 mm (0.04-0.08 inches).

These dimensions are important for several reasons. Firstly, they allow scientists to accurately measure and transfer liquids. The graduations on the side of the beaker help in obtaining precise volume measurements. The height and diameter of the beaker also determine its capacity, in this case, 200 ml.

Additionally, the dimensions of the beaker play a role in its stability and safety. The wider base provides stability and reduces the risk of tipping over. The height of the beaker allows for easy pouring and prevents spills. The thickness of the glass ensures durability and resistance to breakage, although caution should still be exercised to avoid thermal shock and mishandling.

It is worth noting that the dimensions mentioned here are approximate and can vary slightly depending on the manufacturer and specific design of the beaker. It is always recommended to check the markings on the beaker itself for accurate measurements.

In conclusion, a 200 ml beaker typically has a height of 8-10 cm, a diameter of 6-7 cm, and a glass thickness of 1-2 mm. These dimensions allow for accurate liquid measurements, stability, and safe handling in laboratory settings.

200 ml beaker price

The price of a 200 ml beaker can vary depending on various factors such as the brand, material, and quality. In general, a 200 ml beaker is a common size used in laboratories for various purposes, including measuring and mixing liquids.

When it comes to pricing, plastic beakers are generally more affordable compared to glass beakers. Plastic beakers are commonly made from materials such as polypropylene or polyethylene, which are durable and resistant to chemical reactions. These beakers are often priced between $1 to $5, depending on the brand and quality.

On the other hand, glass beakers are more commonly used in scientific research and educational settings. They are preferred for their transparency, heat resistance, and chemical inertness. The price of a 200 ml glass beaker can range from $5 to $20, depending on the brand, quality, and additional features such as graduations or spouts.

It is important to note that prices can also vary depending on the supplier or retailer. Online marketplaces and scientific supply stores may offer different prices for the same beaker. Additionally, purchasing in bulk can often lead to discounted prices.

When considering the price of a 200 ml beaker, it is also essential to consider the intended use and the required specifications. Some applications may require beakers with specific features or certifications, such as beakers with a low temperature coefficient or beakers that are compliant with certain regulations. These specialized beakers may be priced higher than standard ones.

In conclusion, the price of a 200 ml beaker can range from $1 to $20, depending on factors such as the material, brand, quality, and additional features. It is recommended to compare prices from different suppliers and consider the specific requirements before making a purchase.
