Warning:

 

Use caution when working with any polymer tubing under pressure:

• Always wear eye protection when near pressurized polymer tubing.
• Extinguish all nearby flames.
• Do not use tubing that has been severely stressed or kinked.
• Do not use nonmetallic tubing with tetrahydrofuran (THF) or concentrated 

nitric or sulfuric acids.

• Be aware that methylene chloride and dimethyl sulfoxide cause nonmetallic 

tubing to swell, which greatly reduces the rupture pressure of the tubing.

Attention:

 

Manipulez les tubes en polymère sous pression avec precaution:

• Portez systématiquement des lunettes de protection lorsque vous vous 

trouvez à proximité de tubes en polymère pressurisés.

• Eteignez toute flamme se trouvant à proximité de l’instrument.
• Evitez d'utiliser des tubes sévèrement déformés ou endommagés.
• Evitez d'utiliser des tubes non métalliques avec du tétrahydrofurane (THF) ou 

de l'acide sulfurique ou nitrique concentré.

• Sachez que le chlorure de méthylène et le diméthylesulfoxyde entraînent le 

gonflement des tuyaux non métalliques, ce qui réduit considérablement leur 

pression de rupture.

Vorsicht:

 

Bei der Arbeit mit Polymerschläuchen unter Druck ist besondere 

Vorsicht angebracht:
• In der Nähe von unter Druck stehenden Polymerschläuchen stets Schutzbrille 

tragen.

• Alle offenen Flammen in der Nähe löschen.
• Keine Schläuche verwenden, die stark geknickt oder überbeansprucht sind.
• Nichtmetallische Schläuche nicht für Tetrahydrofuran (THF) oder 

konzentrierte Salpeter- oder Schwefelsäure verwenden.

Durch Methylenchlorid und Dimethylsulfoxid können nichtmetallische Schläuche 

quellen; dadurch wird der Berstdruck des Schlauches erheblich reduziert.
