Hamilton offers multiple Optical Dissolved Oxygen (ODO) sensor caps depending on the application.

ODO H0 / H3 Caps

H0 Cap (Ref 243515) – Replacement cap for VisiFerm ECS, VisiFerm RS-485, VisiPro, and VisiWater products.

H3 Cap (Ref 10068400) - Replacement cap for VisiFerm mA products.

Both H0 and H3 caps provide the fastest response time and are compatible with most fermentation and cell culture media. These caps are steam sterilizable, autoclavable and CIP compatible. The H0 cap directly replaces our older P0 cap (Ref 242427) and is suitable for use on all VisiFerm, VisiPro, and VisiWater sensors.

Cross sensitivities and resistance for the ODO H0 / H3 Caps

Measurements not influenced by: Carbon Dioxide
Wetted parts resistant to: Ethanol
Wetted parts not resistant to: Chlorine, Ozone, and organic solvents such as Acetone and Tetrahydrofuran (THF)

ODO H2 / H4 Caps

H2 Cap (Ref 243505) – Replacement cap for VisiFerm ECS, VisiFerm RS-485, VisiPro, and VisiWater products.

H4 Cap (Ref 10078261) - Replacement cap for VisiFerm mA products.

The H2 and H4 caps are specifically designed for increased chemical resistance. These caps are recommended for processes containing lipophilic compounds, oil-like substances, and aggressive chemicals that may attack silicone coatings. The convex tip also helps prevent bubble formation in aerated processes. both products are steam sterilizable, autoclavable and CIP compatible. The H2 cap replaces our older H1 and P1 cap (Ref 243500 and 243510) in non-abrasive applications.

Cross sensitivities and resistance for the ODO H2 / H4 Caps

Measurements not influenced by: Carbon Dioxide, lipophilic compounds
Wetted parts resistant to: Organic solvents such as Ethanol, Acetone, (THF), Heptan, Dimethylformamide
Wetted parts not resistant to: Chlorine and Ozone gases

L0 Trace ODO Cap

L0 Cap (Ref 243530) – The L0 Cap is optimized for trace measurements from 1 to 2000 PPB (µg/mL) and stable against active chlorine and chlorine dioxide. This cap is ONLY for use with the VisiTrace sensors.

Cross sensitivities and resistance for the ODO L0 Cap

Wetted parts resistant to : Standard cleaning solutions (CIP, NaOH)
Wetted parts chemically stabilized against: Standard disinfection solutions (Chlorine Dioxide, active chlorine)
Wetted parts not resistant to: Organic solvents such as Acetone and Tetrahydrofluran (THF)
