Rapid Mix SFA-20
Rapid Mix Accessory SFA-20
The Hi-Tech Scientific SFA-20 is a stopped-flow accessory used to mix reagents for short-lived reactions. The SFA-20 has an empirical dead time of less than 8 ms, and when used with Agilent Cary spectrophotometers monitors reaction rates up to 100 s-1.
The SFA-20 is available in three additional versions that enable microvolume mixing or mixing of more than two reagents. Optional extras include a pneumatic drive attachment, anaerobic kit, and a range of different size syringes.

Product Details
Features
- High precision, gas-tight syringes mounted on a rigid drive platform outside the thermostatically controlled sample circuit stop the flow precisely and instantaneously.
- Easy set-up for variable ratio mixing applications: syringes are mounted outside the sample circuit, providing easy and rapid replacement.
- The platform, syringe mounting blocks, and thermostatted sample circuit are constructed from chemical-resistant materials to protect the instrument from spills and chemical attack.
- The flow circuit has no seals, so a wide temperature range of 0–80 °C can be achieved using an external thermostatted circulator/cooler.
- Inert sample circuit reagents travel in the inert sample circuit through an umbilical cord to the flow cell containing a high-efficiency T-format mixer.
- The SFA-20 can be driven by hand. A pneumatic drive can be added as an optional extra for better reproducibility. It is highly recommended for multimixing (mx) versions.
