Aqua-Hold Pap Pen记号笔

The Aqua-Hold Pap Pen draws a liquid repellent barrier around a section of tissue. Used like a paint pen, you just draw a well on a slide. The barrier creates the proper surface tension to hold aqueous solutions such as costly antibody and other valuable specimens. After application, the barrier material is insoluble in alcohol and acetone but can be removed after staining with xylene. Each pen holds 13ml of long-lasting material, making hundreds of wells.

Aqua-Hold Pap Pen在一部分组织周围绘制了防水屏障。 像油漆笔一样使用，你只需在幻灯片上绘制一个井。 屏障产生适当的表面张力以保持水溶液，例如昂贵的抗体和其他有价值的标本。 施用后，阻隔材料不溶于醇和丙酮，但可在用二甲苯染色后除去。 每支笔可容纳13毫升持久耐用的材料，可生产数百口井。
