The magnetically-stirred variable volume view cell apparatus, which was used to measure solubilities, is shown in Figure 2. The 2 in. o.d. x 5/8 in. i.d. 304 ss cell (28 mL usable volume) contained a 1 in. diameter by 3/8 in. thick sapphire window. A piston with two 90-durometer buna-N o-rings separated the experimental fluid from the pressurizing fluid, C02- Pressure was controlled by a 175 mL Lee Scientific model 501 computer controlled syringe pump. The view cell... 

Figure 2.4-3 Apparatus based upon a variable-volume view cell with a computer-controlled ISCO syringe pump. Type A recirculation mode for adding or removing solutions, emulsification through a capillary, and/or optical access. Type B reciprocating pump for turbidimetry studies of latexes or suspensions.
