AGAR TABLETS (OXOID AGAR NO.3)
Code: CM0049
Description
Compressed tablets of a pre-weighed amount of agar which are especially useful for solidifying liquid media or for the preparation of semi-solid media. Oxoid Agar Tablets are standardised to produce a satisfactory gel when dissolved in 10ml of liquid. This eliminates batch to batch variation and the differences found between one type of agar and another. The use of these tablets obviates weighing and filtration thus leading to considerable time saving.
Technique
To produce a satisfactory gel for plate cultures and slopes, add 1 tablet to every 10ml liquid medium and autoclave at 121°C for 15 minutes. With very acid media it is advisable to use 2 tablets to every 10-15ml of medium. In order to prepare semi-solid agar use 1 tablet to every 100ml of liquid medium.
