Gallium Metal - 99.99% Pure 1kg

Our best value per gram, and the size that makes sense for repeat use. One kilogram of 99.99% pure gallium at $1.60/g — against $2.02/g at 250g and $2.80/g at 20g.

This is the research, industry and institutional quantity: laboratories running ongoing work, universities supplying multiple departments, and schools that would rather buy once than reorder every year.

What you get

• 1kg of 99.99% (4N) pure gallium in a sealed container
• A Safety Data Sheet, supplied with every order as standard
• Certificate of analysis with lot number and assay, available on request

Gallium is dense — 5.91 g/cm³ — so a kilogram is only about 169 mL. It is a good deal smaller than most people picture, roughly the volume of a coffee cup.

Where a kilogram gets used

Temperature calibration. Gallium's melting point is a defining fixed point on ITS-90 at 302.9146 K, which is where 4N purity genuinely matters rather than merely sounding good.

Liquid metal research. Thermal interface work, soft robotics, stretchable conductors and alloying — see gallium for science. If you need a room-temperature liquid rather than one that must be warmed, look at GaInSn eutectic instead.

Repeat teaching use. Gallium is not consumed by melting and resolidifying. A kilogram divided into working vials serves a science department indefinitely.

Availability and lead time

When this size is in stock it dispatches from Perth within 1–3 business days like everything else. If it is showing as sold out, contact us — we restock this size to order and can usually give you a firm date.

Quantities above 1kg are available to universities, research institutions and industrial buyers on request. Contact us for a written quote — we can generally better the online rate on volume.

Handling

Gallium is non-toxic and safe to handle with normal care. Wash hands after handling and don't ingest it.

Keep it away from aluminium. Gallium permanently embrittles aluminium and the damage cannot be reversed — at this quantity that warrants real attention to where it is stored and decanted. It also stains fabric and porous surfaces. Store sealed and below 29°C where practical.

For institutional buyers

We invoice against ABN 42 883 208 403 and accept school and university purchase orders. Written quotes show ABN, quote number, ex-GST line pricing, freight and a validity date. See for schools and universities.
