Swabs & Inoculating Loops

Heathrow Scientific inoculating needle/loops are disposable laboratory tools that provide the choice to spread or pick colonies and cultures without risk of contamination, using the loop end to uniformly streak gel surfaces and the needle end to remove colonies from media. Hach cotton swabs are presterilized cotton-tipped swabs with hardwood sticks specifically used to transfer colonies from positive membrane filtration plates to confirmation broth during microbiological water quality testing procedures for confirming the presence of indicator bacteria like coliforms and E. coli.
