UV/VIS fiber optical flow cell with variable optical length (0.05 mm to >1 cm). A unique key feature of the flow cell is the internal hydraulic bypass whereby high flow rates (> 100 ml/min) can be obtained with minimal pressure loss inside the cell even with 0.05 mm optical length – there is no other product alike on the market.
Liquid is only in contact with the PEEK flow body, gaskets (PTFE, Viton or EPDM) and optical window (UV/VIS transparent quartz glass). Connections to the cell is with 1/4-28 UNF threads and will allow many tube diameters. As standard the cell comes fittings for 1/8 OD hard tubing.
TECHNICAL SPECIFICATIONS:
- SMA 905 fiber optical connection
- Optical path length from 0.05 mm to > 1 cm
- Flow rates > 100 ml/min with minimal pressure loss in the cell (internal hydraulic bypass)
- Full/large pH range – All parts are in corrosion resistant materials (PEEK flow body, PTFE, Viton or EPDM gaskets). Only exception is the optical quartz window which can corrode after prolonged use in glass corrosive media (typically hydroflouric acid and strongly alkaline solutions (e.g. 6 M KOH) and at elevated temperatures. Cell is supplied with replacement optical quartz windows.
- Fittings for tight connecting to 1/8” tubing – For other tube dimensions please make a request
- Gaskets/Spacers Materials: PTFE, EPDM or VITON (comes as standard with spacers for optical lengths from 0.05 mm to 10 mm)
