How to Make Broken Glass Agar Agar Jelly YouTube
In 1887 Julius Richard Petri, another worker in Koch's laboratory, modified the flat glass plate and produced a new type of culture dish for media4. The Petri dish was designed with an overhanging lid to keep contaminants out. By the 1890s the culture media we know today, with Petri dishes, peptones and agar, were developed.

3. Pour the dissolved glue solution into the quantitative container, let the glue solution cool down and put it into the thermostat, and leave it at a constant temperature of 20℃ for 4-8 hours. 4. Use the gelometer to measure its strength. The sum of the weight added to the pressure lever is the gel strength of agar.

1 Citation Explore all metrics Abstract Rheological properties of composite hydrogels of agar with carboxymethyl cellulose sodium salt (NaCMC), intended for water conservation, were studied. The viscosity and yield stress of the hydrogels can both increase and decrease depending on the ratio of the polymer components in the hydrogel.
Tried agar for the first time and seems to be doing well. I used a grain from my spawn jar
The agar dissolves in the water and the mixture is filtered to remove the residual seaweed. The hot filtrate is cooled and forms a gel (jelly) which contains about 1 percent agar. The gel is broken into pieces, and sometimes washed to remove soluble salts, and, if necessary, it can be treated with bleach to reduce the colour.

INTRODUCTION According to the US Pharmacopeia, agar can be defined as a hydrophilic colloid extracted from certain seaweeds of the Rhodophyceae class. It is insoluble in cold water but soluble in boiling water. A 1.5% solution is clear and when it is cooled to 34-43°C it forms a firm gel which does not melt again below 85°C.
