Biuret Solution

Can someone tell me, please, what colour dot to use for Biuret solution?

Thanks

According to CSIS, orange (Years 11-12) for larger volumes, but green (years 7-10) for small volume dropper bottles.

In the CSIS appendix B Biuret solution is orange dot - years 11-12. Toxic if ingested. Corrosive due to the presence of the sodium hydroxide (6M); avoid skin contact.

For junior school we use 0.1M copper sulfate and 1M sodium hydroxide - green dot.
