Product Details
The kit includes caps designed to fit plain end culture tubes and flasks with Delong style necks or ports, molded from durable, autoclavable polypropylene (PP). The caps feature ridges inside that provide a secure grip and facilitate gas exchange. They are available in five colors for easy sample identification and organization. The design maintains sterility without the need for cotton plugging and reduces sample evaporation compared to traditional cotton methods, offering the same benefits of evaporation control and sterility as stainless steel closures.
