The Sentry ISOLOK MSE automatic point sampler is designed for sampling toothpaste, peanut butter, tomato paste, juice concentrates – even rocket propellant. Like any piece of equipment, it sometimes needs repairs and maintenance. But it can be challenging to know how to make strategic decisions around [maintaining sampling equipment](https://532305.hs-sites.com/repair-replace-equipment). Here’s how to keep your ISOLOK MSE sampler working properly.
## Seal Replacement challenges
The ISOLOK MSE has a variety of seal locations and sizes within its design. For some operators and maintenance professionals, properly maintaining the specialized parts on the ISOLOK MSE sampler can be challenging.
- The amount of seals within the sampler can cause difficulty in isolating what might be causing errors
- Incorrect placement of seals can cause poor function and allow air into the process stream
- Incorrect seal replacement can cause the sampler to jam – which leads to unreliable sampling
Replacing seals and maintaining equipment can be confusing when just looking at a product manual, and IOMs and spec sheets can provide only so much information.
