我们在进行农业螨类研究过程中,根据需要,制做了一种有柄玻璃针,用以粘取体小柔软螨类,最为适宜。这种针针尖比头发的二分之一还细,针体柔软,不易折,经过使用,以该针粘取螨类,对螨的外骨骼不易损伤,而且容易操作,使用方便,克服了以往使用毛发太软,不易控制的缺点,也克服钢针过硬,易损伤螨类外骨骼。 制作方法 将酒精喷灯预热点燃,用钢锉将直径5mm玻璃截成8cm长,两端缠上纱布,以免玻璃棒受热后烫手,双手捏住,把玻
In the process of agricultural mites research, we made a glass handle with needles according to our needs, which is most suitable for sticking small soft mites. The needle tip is thinner than one-half of the hair. The needle body is soft and not easy to be folded. After being used, the needle mites can not easily damage the exoskeleton of the mite, and is easy to operate and easy to use, thus overcoming the problems of the past The use of hair is too soft, not easy to control the shortcomings, but also to overcome the needle too strong, easy to damage mites exoskeleton. Production methods Preheat the alcohol burner, with a steel file 5mm diameter glass cut into 8cm long, wrapped around the gauze at both ends, in order to avoid hot glass rods heated, hands pinch the glass
