为了提高血球稀释液的质量和过滤效率 ,我们研制了一种血球稀释液双重过滤装置。该装置能同时对原液进行双重过滤 ,大大地提高了过滤的效率和滤液的质量。 In order to improve the quality of blood dilution and filtration efficiency, we have developed a dual dilution of blood cell filtration device. The device can double-filter the liquid at the same time, greatly improving the filtration efficiency and filtrate quality.
