一次性无菌L型涂布棒

L-shape allows application across the entire Petri dish or plate surface

Smooth spreading surface with slight upward return reduces the risk of damaging the agar sample

Spreaders are presterilised, eliminating the need for flaming or autoclaving

L型设计使其能在整个培养皿或板的表面操作自如

涂布棒的光滑表面和末尾端稍朝上的回勾设计，降低了划破琼脂平板的风险

涂布棒已灭菌，不需要灼烧或进行高温高压菌
