Posted on: October 27 2014Geomycin cream is no longer available. Is this a loco?
Answer
Given the concentration of the solution you have = 1mg/ml You do not have a play area. As a gelvormer you can use Hydroxypropylcellulose (Klucel GF), which you should dissolve in a concentration of 5% in the gentamycin solution. Adding an intermediate fabric to avoid clumping is not included. You would need at least 5 G glycerin and you already have a concentration reduction by solving 5 g HPC. But after a certain wait time, the HPC, slowly added stirring well to the gentamycin solution, will probably solve it. Meanwhile, cover the cooking vessel well!
more possibilities offer for the preparation of this gel when one uses the Gentamycin solution 3mg/ml seen than per 100 g gel only 34 ml of gentamycin solution is needed. Over 66 ML remains for the preparation of a gel, which can therefore be sterilized separately using heat. I n a second stage is diluted with the gentamycin solution .
In both cases, the gel is filled in a sterilized tube. Sterilization of the tube is possible by heat, after wrapping the tube in parchment paper. A boiling pressure pan can serve as an alternative to the classic autoclave. After sterilization, the wrapped tube is dried. The cap of the tube is treated with alcohol 70 °
The shelf life of the gel is limited to 1 month under preservation in the refrigerator.
