Manufactured in the UK: Our Gold Chloride 0.1% Aqueous Solution is manufactured and bottled using non‑toxic, chemical‑resistant containers, providing reliable and trusted quality to our customers.

Frequent Uses

Neurohistological Staining

Commonly used as a reducing agent to visualise neurons and nerve fibers by replacing bound silver with gold grains in staining techniques such as Bielschowski, Gomori, Golgi and Fontana.

Toner in Silver Stains

Used as a toner in methods like Grocott’s methenamine silver (GMS) stain, aiding enhanced contrast of fungi and argentaffin granules.

Colloidal Gold Preparation

Can be used as a precursor for preparing colloidal gold nanoparticles for EM, immunolabelling and nanotechnology applications.
