BD BBL diagnostic reagent and stain droppers

With our 18 varieties of diagnostic droppers, microbiologists now have a solution to the problem of perishable identification reagents and stains. Featuring reagents hermetically sealed in an ampule to protect them from chemical instability, the droppers provide shelf-life ranging from one to three years, with no refrigeration.

Ready-to-use design

Since the droppers are ready to use, no mixing or measuring is required.

Drop-by-drop dispensing

To perform the tests, simply hold the dropper upright and squeeze it to crush the ampule inside. You can then invert the dropper to dispense the solution drop by drop.

One-day supply

Each dropper contains a one-day supply of reagent or stain, thus reducing the waste and inconvenience associated with bulk reagents.
