LyoQuick Freeze-Dried Bacteria
Lyophilized bacteria in an easy-to-use self-contained
rehydration and dispensing tube . Each tube contains two
ampules, one containing freeze-dried bacteria and one containing sterile rehydration broth . Simply pinch the tube to break the internal ampules and let the freeze-dried organisms rehydrate, then dispense the rehydrated organisms into broth or onto agar through the dropper tip . The unique design eliminates several steps typically required for the rehydration of freeze-dried cultures, greatly reducing the risk of contamination .
Bacterial Classification and Morphology Set
This culture set will enable your students to observe firsthand the three basic shapes of bacterial cells . Set includes individual tube cultures of Bacillus subtilis (rods/bacilli), Micrococcus luteus (spheres/cocci) and Rhodospirillum rubrum (spirals/spirilli) .
Bacterial Collection
Convenient collection of six different bacteria cultures representing different chemical and morphological

Bacterial Pigmentation Set
Demonstrate the diversity of pigments produced by bacteria with this set . Set includes individual tube-cultures of Micrococcus roseus (pink), Serratia marcescens (red), and Micrococcus luteus (yellow) .
Fungal Cultures
Maintenance requirements for fungal cultures are similar to those for bacterial cultures . Fungal culture media are typically more acidic and higher in carbohydrates than bacterial media . Fungal cultures take five days to develop .
