Hello Michael

First of all you should know that the endotoxin test has different
methodology, which are Gel Clot, Turbidimetric and chromogenic, it is in
your budget to evaluate which one can help you best.

The most economical (Gel Clot) would give you semi-quantitative results,
but in exchange it would have about 50 determinations per 5 mL vial
(limitations apply) and in terms of equipment you only need a heating
block, automatic pipettes, borosilicate tubes, and reagents ( Lysate,
endotoxin standard and pyrogen-free water) and an all clear oven is
calibrated and qualified, from there there are many possibilities,
depending on your substrate and the way to analyze it.

The turbidimetric and chromogenic method, although it gives you a more
accurate value, the cost is higher, but today there are highly automated
options such as the Charles River PTS, then there are more sophisticated
equipment with a relatively learning curve. short.

Finally, it all depends on your budget, in my opinion I would start with
Gel Clot, it will take longer but it gives good results, and remember that
the USP places it as one of the first options.

Greetings
