Viton Internal Standard Kit (020-049-609) is constructed with highly resistant Viton tubing for use with HF and high concentrations of HNO3. It is designed to accommodate the automated addition of either an internal standard or ionization suppression solution by means of a metered flow and mixing through peristaltic pump tubing.

The kit consists of 2 stop Red/Red (1.14mm ID) Viton Pump Tubing for the sample, 2 stop Orange/Orange (0.89mm ID) Viton Pump Tubing for the internal standard, and Teflon® sample tubing connected with an acid-resistant plastic ‘‘Y’’ connector.
