Petri dish necklace | sterling silver
The moment you wait for in the lab is 24 hours later. Plate a sample, incubate, and return to find growth. The Petri dish that Julius Richard Petri designed in 1887 as an assistant in Robert Koch's Berlin laboratory became the standard vessel for every discovery in modern microbiology. Well over a century unchanged.
The Science Behind the Petri Dish
Julius Richard Petri invented the Petri dish in 1887 in Robert Koch's laboratory while optimising solid-culture techniques for bacterial growth. The design was elegantly simple: a shallow glass dish with a slightly larger lid that overhangs the base, reducing contamination from airborne spores. The agar-agar medium (a seaweed extract) was contributed by Angelina Fanny Hesse. Koch had already identified the tuberculosis bacillus in 1882 and the cholera vibrio in 1883 using earlier plate methods. Petri's dish made plate culture routine and far easier to keep clean. The Petri dish remained fundamentally unchanged for well over a century and now exists in polystyrene. It remains the universal tool for antibiotic susceptibility testing, fungal culture, and every plate-based microbiology assay.

FAQ
Would a microbiologist actually recognise this?
Instantly. The Petri dish is the icon of microbiology. For anyone who has plated samples, waited for growth, and read results, this pendant is unmistakable. It's a quiet signal of lab-based work.
Why was the Petri dish such an important innovation?
Because it solved the contamination problem. Koch's earlier flat plates picked up unwanted microbes from the air every time they were handled. Petri's overhanging lid let a culture be observed without opening it. Koch's own discoveries, the tuberculosis bacillus in 1882 and the cholera vibrio in 1883, predate the dish, and his 1905 Nobel Prize was awarded for his work on tuberculosis. What the dish did was make pure culture a routine any laboratory could repeat, and that routine became the foundation of bacteriology.
What size, material, and chain?
20 mm pendant in 925 polished sterling silver, nickel-free and hypoallergenic. 45 cm sterling silver chain with 5 cm extender. Ships free worldwide via DHL Express in 1-5 business days. Comes ready-to-gift with the 30-day “Love It or Return It” policy.
Is the gold version the same size?
Yes. The petri dish is available in 18k gold vermeil at 20 mm. Same design, same incubation story, same meaning. Material is the only difference.
