Frequently Asked Questions (FAQs)
1. What are weighing bottles used in the laboratory?
Weighing bottles are used in the laboratory for precise weighing of solids. They are typically cylindrical with flat bottoms and are made of glass or durable plastic. Weighing bottles have plug-style glass stoppers that create a seal to prevent spillage or evaporation. They are available in various sizes and are designed to have an extremely low empty weight, making them suitable for use with precision balances.
2. What is the difference between a weighing bottle and a weighing boat?
The main difference between a weighing bottle and a weighing boat is their purpose and precision. Weighing bottles are used for precise weighing of solids and have a cylindrical shape with a flat bottom. On the other hand, weighing boats or dishes are simpler trays or semi-flat items used to hold solids for less precise measurements or bulk amounts. Weighing bottles are designed for precise measurements, while weighing boats are more commonly used for less precise measurements.
3. Why do you use a weighing bottle?
Weighing bottles are used in the laboratory because of their specific features. They have a cylindrical shape with a flat bottom and are closed with plug-style glass stoppers to create a seal. This seal prevents spillage or evaporation during the weighing process. Weighing bottles are also designed to have an extremely low empty weight, making them ideal for use with precision balances. They are available in different sizes to accommodate various sample volumes.
4. How do you weigh bottles for inventory?
To weigh bottles for inventory, place a bottle on the scale and record the weight. Subtract the tare weight (empty weight of the bottle) from the total weight to determine the fluid ounces in the bottle. To calculate usage for each bottle, subtract the ending weight from the starting weight. It's important to keep track of any new bottles added between the start and end to ensure accurate inventory measurement.
5. What is used for weighing samples in the laboratory?
For weighing samples in the laboratory, analytical balances are commonly used for semimicro quantities. It is important to handle objects to be weighed using tongs, paper towels, or gloves, to avoid contamination or errors. Analytical balances provide accurate and precise measurements for laboratory applications.
6. Can you reuse weighing boats?
Weighing boats are designed to be disposable, but they can be washed and reused multiple times. They are biologically inert, resistant to dilute acids, alcohol, and bases, and can withstand temperatures up to 140°F. However, it is important to ensure proper cleaning and sterilization before reuse to avoid any potential cross-contamination or measurement errors.
7. Why is weighing by difference more accurate than direct weighing?
Weighing by difference is considered more accurate than direct weighing because it eliminates the need for a container, reducing potential measurement errors associated with the container's weight. With the weighing-by-difference procedure, scale calibration errors are also minimized as exact zeroing of the scale is not essential. Any error in the initial reading is automatically canceled when the subtraction of the readings occurs, resulting in a more accurate measurement.
8. How do you use a weighing bottle?
To use a weighing bottle, tip it above the container to receive the sample, allowing a small amount to fall out. Then, tip the weighing bottle back up and gently tap it to ensure all of the substance falls back into the bottle and does not remain on the bottle rim. This technique helps to ensure accurate and precise weighing of the sample using the weighing bottle.
