Customers can make selections based on the oxygen bomb electrode, which is more accurate.

For those who frequently use calorimeters, sometimes they encounter the issue of oxygen bomb leakage. Oxygen bomb leakage can cause inaccurate test results. How do we check if the oxygen bomb is leaking? Inflate the oxygen bomb with oxygen and then submerge it in water. If bubbles appear in the water, it indicates leakage. If it leaks, the sealing ring needs to be replaced. The oxygen bomb comes with three sealing rings: large, medium, and small. If this position leaks, replace the large sealing ring; if this position leaks, replace the medium sealing ring; if this position leaks, replace the small sealing ring. Now, let's start by deflating the oxygen bomb.

After opening the oxygen bomb, you can directly see the large sealing ring. First, replace the large sealing ring. The large sealing ring is most prone to leakage and is frequently replaced.

Now, let's use a wrench to open the head of the oxygen bomb and disassemble it. Just clamp it with this small wrench.
