Twister spray chamber, includes Helix CT locking screw & seal (1 pc), UniFit with 1.6mm OD x 0.75mm ID x 700mm long tube (1 pc) & 19mm ball joint clip. Made from borosilicate glass, 50mL volume. Compatible with Thermo 6000 Duo ICP-OES.The Twister features a baffle, which efficiently removes larger droplets, producing a smaller mean droplet size entering the plasma. Resulting in a more robust plasma, making the Twister an excellent choice for applications requiring the best possible precision & for both high TDS or organic sample matrices.The unique Helix CT interface consists of two parts, a ConstantTorque Locking Screw & chemically inert PressFit ferrule. The main feature of the Helix CT is the built-in, ratcheting torque control mechanism that allows for a consistent, zero dead volume, inert seal of the nebulizer.Replacement parts include NC1943061 & NC2081825, suggested to replace every 6 months.Glass Expansion is ISO 9001:2015 certified by AB Certification, No. AU4501-9001
