[交流] 求助一种测氧结合常数的试验设备

氧气与血红蛋白结合常数的测量用到了一种设备flow-flash apparatus ，因为看的是英文文献，不太清楚设备flow-flash apparatus 到底是什么样的？哪里有卖？希望知道的好心人能帮帮我，谢谢大家啦

附上英文原文介绍：
A brief description of the current flow-flash apparatus is as follows.The reservoirs for reactants were glass cylinders of 5-ml capacity equipped with the inlet and outlet for gases at the top. The solutions were stirred with magnetic stirrers installed in the bottom. The reactant solutions were transferred to horizontal drive syringes by pulling a rod block to which were attached the plungers, and then forced to pass through a jet mixer into an observation tube by a stroke of a pneumatic piston (4.0 kg/cm2). Both reservoirs and drive syringes were mounted in a thermostated aluminum block. The volume of reactant required for one shot was 260 l for each reservoir. The observation cell was fabricated from a block of glass ceramics. A hole 2 mm in diameter was drilled and the two ends were sealed with quartz windows (10 mm apart). The top half of the block was removed by cutting horizontally through the middle of the hole leaving a rectangular opening (2 X 8.5 mrn), which was covered with a quartz window to receive the photolyzing beam.
