Antibiotics, Antimycotics & Preservatives

Thomas Scientific offers an extensive range of antibiotics, antimycotics, and preservatives ideal for various applications within the laboratory. Cell culture antibiotics are primarily used for microbiology and cell culture work and can prevent contamination of bacterial cultures by other unwanted bacteria.
Antibiotics available include penicillin, streptomycin, and tetracycline. Antimycotics can prevent the growth of fungi and are perfect for laboratory applications to prevent or kill fungi. The selection available includes amphotericin B, nystatin, and fluconazole.
Preservatives are essential in the laboratory to prevent the growth of microorganisms in laboratory reagents, solutions, and samples. They’re ideal for extending the shelf life of your diagnostic kits, buffers, staining solutions, and more, providing precise, accurate lab results.
