We are closed for a short period to rest and recharge from 21st July to 2nd August. We thank you for your patience and understanding. Orders will be dispatched upon our return. URGENT orders (restricted to air scribe styli, o-rings and spares) will be dispatched immediately as always - we have somebody looking after these so you're not left without!

Air Scribe Spares & Maintenance

At ZOIC PalaeoTech, we only use the highest grade tungsten carbide for our styli. Quality tungsten carbide is essential to withstanding the trials and tribulations of fossil preparation.

Tungsten carbide is used for styli in fossil preparation because it is the only material that is wear-resistant enough to take the abrasion of rock. Its ability to maintain a point or set geometry makes it perfect for fossil preparation applications. However, due to its manufacturing process and nature as a sintered material it can also be brittle if used improperly or dropped. We only source our tungsten carbide from a manufacturer with stringent quality control checks.

We also make custom styli for ZOIC tools as well as other brands. Do you need a chisel on your ZOIC Chicago? A slightly longer stylus on your Microraptor? Perhaps a replacement for a nib for another tool. Just drop us an email with your requirements.
