clinostat clock type
A combustion tube is a laboratory glassware used primarily in organic chemistry for conducting combustion reactions. It's a straight, narrow tube made of heat-resistant glass, usually borosilicate glass, with one end sealed.
Here's how it typically works:
- Preparation: The sample to be combusted is usually placed inside the combustion tube. This sample is often an organic compound or a mixture of compounds.
- Sealing: After loading the sample, the open end of the tube is sealed, often using a stopper or a glass rod. This ensures that the combustion reaction takes place within a closed system.
- Combustion: The sealed tube is then placed in a combustion furnace, which raises the temperature to a level where combustion of the sample occurs. This typically involves heating the sample in the presence of excess oxygen.
- Collection of Products: As the sample combusts, it reacts with oxygen to produce carbon dioxide and water vapor, along with other possible products depending on the composition of the sample. These products are collected and can be analyzed using various techniques such as gas chromatography.
- Analysis: The collected products can provide valuable information about the composition of the original sample. For example, the amount of carbon dioxide produced can be used to determine the carbon content of the sample, which is useful in determining its molecular formula or identifying functional groups present in organic molecules.

Cork to fit boiling tube cork
To fit a cork into a boiling tube in a laboratory setting, you'll want to ensure a snug fit to prevent any leakage or contamination. Here's a simple guide to achieve that:
Select the right size cork:
Ensure that you have a cork that matches the diameter of your boiling tube. It should fit tightly but not so tight that it's difficult to insert or remove.
Prepare the cork:
If the cork is new, it might be stiff. To make it more pliable and easier to insert, you can soak it in warm water for a few minutes. This will make it more flexible and easier to work with.
Trim if necessary:
If the cork is too long for the boiling tube, you can trim it to size using a sharp knife. Make sure to cut it evenly to maintain a tight seal.
Test fit:
Before inserting the cork into the boiling tube, test its fit to ensure it's snug but not too tight. You want it to create a good seal without being difficult to insert or remove.
Insert the cork:
Once you're satisfied with the fit, carefully insert the cork into the boiling tube. Apply even pressure to ensure it goes in straight and doesn't get stuck.
Secure the cork:
If necessary, you can use a rubber band or laboratory tape to secure the cork in place and provide additional sealing.
Check for leaks:
After inserting the cork, visually inspect the seal to make sure there are no gaps or leaks. You can also perform a leak test by filling the boiling tube with water and observing for any signs of leakage.
Monitor during use:
While using the boiling tube, periodically check the cork to ensure it remains securely in place and continues to provide a tight seal. If you notice any signs of wear or deterioration, replace the cork as needed.
