Gellan Gum LAT

Gellan Gum LAT is a kind of low acyl gellan gum, specially processed for Plant Tissue Culture and Micro-organism Tissue Culture application. It has widely been applied by labs to be as subsitute of Agar. The gel strength and the transmittance of this product could be adjusted subject to customer's actual application. This kind of gellan gum could bear 20 psi pressure for 20 minutes. Gellan Gum LAT produces a very transparent gel ≥85% transmittance and gel strength between 400-700 g/cm＾2; Use at 2-4 g/L. If the customers request higher gel strength, we can also produce with below standard: gel ≥90% transmittance and gel strength between 700-1100 g/cm＾2. While for those who need very strong gels, we could supply 1300 g/cm＾2 gel strength and ≥85% transmittance gellan gum. As Professional Producer for gellan gum, our Gellan Gum LAT has been applied by labs form Canada, Germany, Hondrus, Uganda, India with success. CAS NO. 71010-52-1.
Feature: 1. Excellent Acid/ Heat Stability; 2. Brittle Texture and Clear Gels (transmittance ≥85%); 3. Heat Irreversable; 4. Low Dosage; 5. Stable Supplying, substitute of Agar.

Typical Dosage of Gellan Gum LAT: Regular recommended dosage is 0.015%-0.4% subject to different application. Dispersion and Dissolution: To disperse Gellan Gum LAT without lumps. Premix the powder with the other dry ingredients and pour the preparation into the liquid underefficient stirring. Continue stirring to obtain a complete dispersion or disperse it in a non-solvent medium (oil or other). The dissolution of the product depends on the medium and the process: it is improved by heat treatment (time, temperature), shear stress (stirrer, homogenizer). A complete dissolution can be rapidly obtained by boiling for 5-10 min or at around 85-90 centigrade for 10-15 min with sequestrants.
