Ceftazidime kinetics of diffusion in inoculated agar plates

Method for staining and preserving agar gel diffusion plates.

An improved method for the preservation of agar gel precipitin lines has been developed.

Syneresis and delayed detachment in agar plates.

Biogels made of crosslinked polymers such as proteins or polysaccharides behave as porous soft solids and store large amounts of solvent. These gels undergo spontaneous aging, called syneresis, which consists of the shrinkage of the gel matrix and the progressive expulsion of solvent. As a result, a biogel originally casted in a container often loses contact with the container sidewalls, and th...

Multiple syringe inoculator for agar plates.

The design and operation of a manually operated multiple syringe inoculator was described. Either 9 or 21 inoculations of constant volume could be made simultaneously. Up to 100 plates could be inoculated in 15 min with excellent reproducibility. No contact occurred between the inoculating needles and the agar surface. Construction was simple and inexpensive, with minimal maintenance.
