Carbon Dioxide Pump

The SFT- 20 liquid carbon dioxide pump from Supercritical Fluid Technologies (SFT) delivers a flow rate of 200 ml/min without the need for external cooling baths. The SFT- 20 generates pressures up to 10,000 psi (69 MPa). Utilizes dual sapphire syringe pump technology. The SFT- 20 may be acquired as a stand alone CO₂ pump or as part of SFT’s SF T-2000 Supercritical Fluid Extractor. SFT www.supercriticalfluids. com 302-738-3420

Threaded, Off-Line Diaphragm Seals

selves to complex seal assemblies. The seals have a large diaphragm, which increases accuracy and allows for low pressure readings. Welded diaphragms allow the lower housing to be removed for cleaning without losing fill. There are a variety of process connections available, including ¼”, ½”, ¾”, and 1” NPTF. The standard diaphragm and lower housing material is 316 SS, with many other exotic materials available. REOTEMP www. reotemp.com 800- 648-7737

Toxic Gas Monitor

[Correction: Note that when this product appeared in the November/ December issue of G&I, the photo was incorrect]

The SC-01 single toxic gas monitor from RKI features interchangeable sensors that are automatically recognized by the instrument. Sensors offered for NH₃, CO,

Cl₂, H₂S, H₃, and SO₂. An extender allows the sensor to be attached to the end of a 10-foot cable. LCD display shows gas reading, battery level, current time, and will automatically backlight in alarm conditions. Standard alarm types include can be set to latching or self-resetting.
