petri dish necklace | 18k gold vermeil
When Julius Richard Petri designed a shallow lidded dish in Robert Koch's Berlin laboratory in 1887, he solved a problem that has defined microbiology ever since. This gold version marks that moment for anyone who has ever grown something in one.
The Science Behind the Petri Dish
Petri's dish solved the contamination problem that plagued flat-plate cultures. The overhanging lid created a sealed environment where agar medium (contributed to the lab by Angelina Fanny Hesse) could support bacterial growth without airborne contamination. Robert Koch had identified Mycobacterium tuberculosis (1882) and the cholera vibrio (1883) with earlier plate methods. Petri's dish turned plate culture into a routine any laboratory could repeat. The design remains essentially unchanged well over a century later. Antibiotic susceptibility testing, microbial isolation, cell culture initiation, mycology, and every routine clinical microbiology lab still depends on this single piece of glassware.

FAQ
Why the petri dish in gold?
For someone defending a dissertation in microbiology, or celebrating 10 years in the lab, or the PhD supervisor gifts it to their departing student. Gold elevates it without changing what it means.
What is the history behind agar in the petri dish?
Angelina Fanny Hesse learned about agar from her mother's kitchen (it is seaweed-derived gelatin used in cooking). She suggested it to her husband Walther, who was assisting Koch. Agar solved the problem of solidifying culture medium without melting at incubation temperature. The Petri dish and agar became inseparable.
What are the material, size, and chain?
20 mm pendant in 18k gold vermeil (sterling silver core with 2.5 micron gold plating), nickel-free and hypoallergenic. 45 cm gold vermeil chain with lobster clasp and 5 cm extender.
