First developed in 1884 by Christian Gram, the Gram Stain is a fundamental technique used to identify and classify bacteria. In this instance, bacteria are stained with Crystal Violet and Grams Iodine and counterstained with Phenyl Fuschin.
Gram positive bacteria retain the crystal violet and Iodine complex and are stained blue, whilst Gram negative bacteria are counterstained red. The teaching notes have been designed for the teacher with little experience in handling micro-organisms and include step by step diagrams of the practical procedure and the whole experiment can be done in one lesson.
The accompanying booklet entitled ';Safe Handling of Micro-organisms' includes full instructions on safety, aseptic technique, culturing and disposal.
The Gram Stain Kit contains:
- Escherichia coli culture
- Staphylococcus albus culture
