Using swabs in tubes will protect bacteriological, cytological, or serological samples during transportation to analysing sites. Thick-walled tubes prevent the single or dual tips from dehydrating for best retrieval, and feature labels for accurate inventory. Choose tubes dry or prefilled with media which acts as a moisture reservoir for specimen extraction. Shafts are designed short or long to reach any sampling sites and come in different materials for maximum flexibility.
