Tissue Culture Agar

A high-quality gelling agent for preparing solid and semi-solid plant tissue culture media.

Add to your culture medium formulation to create a stable growing surface for in-vitro plant cultures.

Why use agar?

Agar is one of the fundamental components used in solid plant tissue culture media.

When added to an appropriate culture medium and prepared correctly, agar creates a gel-like surface that supports plant material during in-vitro culture.

InVitro Garden Plant Tissue Culture Agar is supplied as a dry powder and can be combined with your chosen tissue culture formulation.

The tissue culture agar provides:

Physical support
A stable surface for plant material and explants.

Medium structure
Transforms an appropriate liquid formulation into a gelled culture medium.

Flexibility
Can be used alongside different basal media and formulations.

How much agar will I need?

As an example, our Aroid Multiplication and Rooting Medium recipes use 7–8 g of agar per litre of finished medium. At this amount:

• A 30 g pack makes approximately 3.75–4.3 litres.
• A 100 g pack makes approximately 12.5–14.3 litres.

These amounts refer to the final volume of prepared medium, not the initial water volume. Agar is a gelling agent, not a complete nutrient medium; combine it with your chosen medium formulation.

Follow the recipe and preparation instructions for your chosen medium, including heating to dissolve the agar and sterilizing the prepared medium. The amount of agar required can differ between recipes.
