Test the grade before you commit to a container

We ship trial samples for every grade we make. Tell us the quantity and the test you intend to run, and we will send a sample sized to that test rather than a token 50 g.

Also used for WhatsApp contact.

Select value is the composite key 'series/slug' (e.g. magnesium-oxide/zh-v2). The option label shown to the user is 'Series name — Grade name' (e.g. Magnesium Oxide — High Purity Magnesium Oxide ZH-V2). Never send or accept a bare slug: light-grade and food-pharma-grade exist in more than one series.

More details (optional)
