Needle Adapter: The needle adapter accessory is for unstable liquid sampling into a bottle with septum. It also features a bottle support which can be customized to fit most bottles. This accessory allows the sample bottle to be inerted with Nitrogen or other gas depending on process requirements so that the sample does not come in contact with air or the atmosphere. The Needle adapter accessory can be configured to fit most bottles with septa and needles come in several different sizes and materials for product compatibility.

Uses: The needle adapter option is suitable for sampling unstable liquids that must be sampled without any contact with the environment. Perfect for flammable, hygroscopic and atmosphere sensitive processes.

Why is the Needle Adapter suitable for pre-polymer solvents?

  • Bottle can be inerted with Nitrogen or other gas suitable to the process.

  • Prevents the process contacting air or moisture.

  • Septum bottles ensure an enclosed environment.

  • Dual needle system allows for venting of fumes away from the operator.

For some applications, sampling into a bottle with a septum cap is an ideal solution. The needle adapter is used to pierce the septum of the bottle.

Due to the nature of the septum, the operator's exposure to toxic fumes / vapors of the sample is limited. This solution is not recommended for slurries, highly viscous products or application than can plug.
