How to maintain Kemmerer bottles

1. To avoid damage, use the case during transport or storage.
2. Store hung from a hook in a vertical position with all valves open. Storing closed many damage the valves.
3. Guard the sampler from blows on the cylinder ends (this may cause them to be knocked out of round), a common cause of sampler leakage.
4. Leakage may also occur from a bent central shaft. When this happens, it is best to replace the shaft.
5. Worn or age-hardened stoppers should be replaced to prevent leakage. Never remove seals when dry. Moisten first, then grasp with a side-to-side motion. Never attempt to remove seal in wet or dry conditions with a direct pulling motion. This will shorten stopper life dramatically.
