小孔管

小孔管是一个空心玻璃管,其上有一个孔,通过它,细胞被吸进库尔特计数器。该管充满盐溶液,电极放置在管的内部和外部,电流流经管中的孔。测量样品时,在管子内部放置一个真空,将细胞或颗粒拉过孔。每次细胞进入孔径孔时,它都会取代盐溶液,从而产生可见的电脉冲。脉冲的大小告诉您细胞(或任何粒子)穿过孔时的大小。脉冲的数量告诉你有多少东西穿过了这个洞。aperture tubes for multisizer

High resolution tubes have an aperture thickness 120% greater than normal apertures thus, extending the time the particle takes to pass through the aperture, giving greater discrimination of particle size.

*使用推荐带主孔管的微珠进行孔管校准。
**校准后,可以使用其他尺寸的微珠来验证孔径的性能。
建议使用孔径尺寸范围为 7-30% 的微珠校准仪器。
