The Canonical Baby Bottle Low-Down
Every bottle I have personally scanned with my Nikon XRF, cross-referenced with what's already out there, with a plain-English take on what the numbers actually mean.
bottles I’ve personally scanned + leach-tested with a Nikon XRF and Niton XL5 Plus

tested clean (Pb non-detect or trace + leach-negative). Most modern major-brand bottles pass.

failed, including some major Western brands not on any other public list.
But here’s what IS actually risky in a baby-bottle shopping decision
The rest of this page is brand-by-brand. Before you scroll into the detail, these are the patterns that actually produce positives in 2025:
Decorated glass bottles with ml / oz paint on the outside. The ml / oz scale is the primary lead source on almost every failing bottle, the paint frit uses leaded flux. Simba (all colors), Oberni, Pigeon standard, Lansinoh, Maymom all fail because of the printed decoration.
DTC / Amazon-only “dino bottle” / novelty bottles from companies you haven’t heard of. Hands Free Baby Bottle came in at Pb 22,324 ppm. If the company operates out of what looks like a residential address, pass.
Imports with measurement graduations in a different language system (Taiwanese Simba, Chinese Pigeon standard). The printing process tends to use older leaded-pigment systems. The safe version of the same brand might be the export-formulated one.
Size-split and SKU-split brands. Hevea: large = clean, small = Pb 4,696. Pigeon: small-oz + copper color = clean, standard decorated = Pb 10,018. Potato: plain + small = clean, handles version = Pb 25,091. Do not trust the brand name alone.
Outdated blacklists. NUK in 2018 was a disaster. NUK in 2025 is clean across the board. If a list you’re reading was written before 2023, the product on the shelf today may not be the product the list is warning about.
Vintage / family hand-me-down glass bottles. Pre-1990 glass baby bottles with any printed decor have a real chance of leaded paint. Do not feed a current baby out of a 1980s bottle.

How to read this
Lead threshold. I use ~100 ppm lead on the surface as my fine/not-fine cutoff. Below that, you are in noise territory, trace manufacturing contamination that does not meaningfully leach into a baby's milk. Above that, you are looking at lead paint or leaded glaze, and that is a different conversation.
Surface vs. leachate. XRF tells you what is on the bottle. A leach test tells you what comes off into the liquid. The CPSC tests a third thing entirely: they grind the whole bottle into powder and test the dust, which averages any surface paint across the mass of the glass. That is how a bottle with visible lead paint can "pass" CPSC and still sit on a store shelf.
Elements that are not lead. My XRF reports 15–30 elements per scan. High titanium = paint pigment, usually fine. High barium = borosilicate glass, fine (Life Factory reads 12,228 ppm Ba because that is what borosilicate is). High chromium + iron = stainless-steel hardware. These are not problems; they are fingerprints of what the bottle is made of.
This list is alive. Brands reformulate. NUK in 2018 was a disaster; NUK in 2025 is clean. A blacklist that never updates is a blacklist that eventually lies.

NUK , 2025
Pb: non-detect · scan #6790
non-detect; Legacy advocacy data (2021) shows 24,000 ppm on old paint, they reformulated
Clean across the board, no Pb detected. Four or five years ago NUK was a disaster (Legacy advocacy documented 19,900–24,000 ppm lead paint on exterior decor in 2021 posts). They reformulated. My 2025 bottle has no detectable lead on the painted exterior. The problem that existed four years ago is not the problem today. Legacy advocacy reporting is what caused the fix.
Source citations from legacy advocates:
post 1 · post 2
Dr Brown's , US large
Pb: 7 ppm · scan #6790
±4 straddles zero
7 ppm with a ±4 error bar that straddles zero. US Dr. Brown's is pharma-style borosilicate with no decorative paint on the glass body, that is the single biggest safety feature. The Cr+Fe signature is the stainless venting piece. Caveat: A follower in Australia sent me two Dr. Brown's bottles in Feb 2025 that glowed on contact with Fluoro-Spec, lead present. Same brand, different supply chain.
Pb=9 is essentially non-detect. The high Cr / Fe / Co / Cu readings are the stainless-plus-brass hardware showing up in the scan.
MAM
Pb: non-detect · scan #6786
Clean. Legacy advocacy references MAM in her 2023 / 2024 glass-bottle roundups in the SAFE category.
Natursutten
Pb: non-detect · scan #6785
Clean. Ti=43,086 looks dramatic but it is titanium dioxide pigment, same chemistry as sunscreen.
BIBS
Pb: non-detect · scan #6816
Safe for lead. High Cr + Cu is a metal component (cap or collar). As=24 is a whisper.
Bobo , large
Pb: non-detect · scan #6789
Clean. Ti spike is paint pigment, not a concern.
Bobo , small
Pb: non-detect · scan #6784
Clean. Unusual Sr / V / Zn profile but no lead concern.
Matyz , regular
Pb: non-detect · scan #6810
Very clean, looks like uncoated stainless or clean silicone.
Matyz , tall
Pb: non-detect · scan #6820
Same profile as the regular, clean.
Numvim
Pb: 19 ppm · scan #6783
Pb=19 is trace. High Cr / Cu / Zn = brass / stainless hardware.
Fdbtl , 2025
Pb: 13 ppm · scan #6799
2024 version was leaded, 2025 is clean
Pb=13 is noise, safe now. The 2024 version was a mess: "Not a safe bottle by any stretch of the imagination. The lead came right off." 2025 version is clean.
Potato , plain
Pb: non-detect · scan #6801
No Pb detected. The U=77 trace is unusual, uranium shows up occasionally in mineral-heavy paint pigments but at that level it is not a health concern.
Potato , small
Pb: non-detect · scan #6796
Clean.
Pigeon , small-oz
Pb: 40 ppm · scan #6817
Pb=40 is under threshold, fine.
Pigeon , copper color
Pb: non-detect · scan #6797
Clean. U=30 trace, harmless.
∼ TIER 2, Trace Pb but proven safe by leach test (2)
LifeFactory
Pb: 43 ppm · Ba: 12,228 ppm
· scan #6812
The single most important case study on this list. Pb=43 on the surface, Ba=12,228 (borosilicate signature). I boiled water in the bottle for 48 hours, microwave-boiled, ran the leachate through my spectrometer twice: zero detectable lead migration. Surface Pb is not the same thing as exposure. This is the difference between lead in glass (locked into the silicate network) and lead on glass (paint, glaze, decals, mobile).
51 ppm is right at the edge of my comfort zone but still under the 100-ppm line, and this is the reformulated version. The original had lead; the COO of Lactation Hub recalled the bottles at a cost of $100,000 to her small company. When a small business eats a six-figure voluntary recall bill to do the right thing, that is the behavior I want to see in this industry. Supporting that company is how we build incentive alignment.

Hands Free Baby Bottle
Pb: 22,324 ppm · As: 5,746 ppm
· scan #6804
22,324 ppm is lead paint, full stop. The As=5746 alongside the Pb is a signature of legacy Chinese ceramic / enamel pigments, lead chromate paint plus arsenic-containing stabilizers. A decorative coating, not a food-grade finish. The company operates out of what looks like a residential address on a river in Oregon. After my video they quietly swapped the product image on their site without notifying existing buyers.
Haakaa
Pb: 11,002 ppm · Cr: 12,561 ppm
· scan #6811
Likely metal component, not silicone body
11,002 ppm on the component I tested, likely a metal cap or collar given the Cr=12,561 / Cu=3,280 signature. Haakaa's signature product is the silicone pump / feeder, and silicone on its own rarely has lead issues. The concern is any plated or painted metal part, not the silicone body. 11,000 ppm on anything a baby can touch is disqualifying.
Simba , blue
Pb: 17,460 ppm · scan #6807
17,460 ppm. The Co=1,436 signature is cobalt tuning the base lead-chromate pigment to blue.
Simba , pink
Pb: 9,840 ppm · scan #6806
9,840 ppm. Same lead-chromate carrier, different color tune.
Simba , orange
Pb: 18,161 ppm · scan #6805
18,161 ppm. Lead chromate is already orange at its base, this is the raw pigment.
Oberni
Pb: 17,645 ppm · scan #6787
17,645 ppm lead plus 4,619 ppm arsenic. Classic leaded-decorative-paint profile.
Pigeon , standard decorated
Pb: 10,018 ppm · scan #6788
10,018 ppm on the standard decorated Pigeon. But note, the small-oz and copper variants tested clean. This is brand-line dependent, not a blanket "avoid Pigeon."
Hevea , small 5oz
Pb: 4,696 ppm · scan #6798
4,696 ppm on the small 5oz. Legacy advocacy documented Hevea leaded back in 2018 and my measurements confirm the historical record.
Clean on the large. Size-split within the brand, my best guess is the smaller bottle uses a different ml / oz graduation printing process that involves a leaded ceramic pigment.
Gulicola
Pb: 3,742 ppm · scan #6793
3,742 ppm plus arsenic. Avoid.
Lansinoh
Pb: 7,077 ppm · scan #6809
Major Western-market brand, previously unflagged
7,077 ppm lead on a major Western-market brand. This is the most consumer-consequential single finding on this list, not a random no-name, not an obscure import. Nobody has flagged this before.
Maymom
Pb: 3,347 ppm · scan #6808
3,347 ppm plus cobalt and titanium. Avoid.
Potato w/Handles
Pb: 25,091 ppm · scan #6818
SKU-specific; plain Potato is clean
25,091 ppm on the handles version specifically. The plain and small Potato bottles tested clean. Do not trust the brand name alone, this is SKU-dependent.
UNKNOWN (?.png)
Pb: 31,354 ppm · scan #6800
Unlabeled at scan time, highest reading in set
31,354 ppm, the highest single reading in the whole session. I did not label this one when I scanned it, so I need to identify it. Worth a deep dive once I pull the photo.
The science basket, what is actually going on
Why most modern plastic bottles are lead-free by default
Polypropylene, PES, Tritan, silicone, none of these polymerization chemistries involve lead. You would have to go out of your way to add lead. That is why the Avent plastic, Tommee Tippee plastic, Bobo silicone, and others test clean without any effort. Lead in a plastic bottle is an accident or a coating; lead in a painted glass bottle is a supply-chain decision.
Why glass bottles with decorative paint are the actual risk category
The bottle body is boring fused silica, fine. The decoration on the outside, ml / oz gradations, logos, colored patterns, is where lead lives. Glass paint that fires at low temperatures needs a frit (a glassy flux). The cheapest low-melt fluxes historically are lead-based. Lead oxide drops the melt point, holds pigment crisply, survives dishwashers. That is why the decorative band on a painted glass bottle is where 99% of positive XRF hits land.
Why components matter more than the body
A painted ml / oz scale on a glass bottle. A colored silicone collar. A brass-plated metal cap. These auxiliary parts are where the lead hides. I scan every component, not just the body. The Haakaa reading above is a component-level finding, not a silicone-body finding.
The CPSC loophole, surface paint averaged into total mass
The federal children's-product test: grind the entire bottle into powder, measure lead concentration in the powder. A 100-gram glass bottle with 5 mg of lead paint on it reads out at ~50 ppm across the whole dust, under the 90 ppm children's-product limit. The baby never licks the powder. The baby licks the painted surface, where the actual concentration is 22,000 ppm. This is why "CPSC-compliant" and "safe" are not the same sentence.
The leach-test reality check
Surface XRF detects presence. Leach testing detects migration. Life Factory is the cleanest example: 43 ppm in the glass, zero migration after a 48-hour boil. Hands Free Baby Bottle is the opposite: the swab wipes lead off onto the swab on contact. If a fluoride-reactive spray glows orange the moment it hits the surface, the lead is not locked into a matrix, it is sitting on top, and it is coming off.
What this adds beyond legacy “lead-poisoning prevention advocates” coverage
Legacy advocates have deep per-bottle coverage of Dr. Brown's, LifeFactory, Avent, Boon, Hevea, old NUK, MAM, and vintage brands, going back to 2017 with narrative posts and a paper trail with CPSC. Her strength is longitudinal evidence.
What is missing from her coverage that is on this list:
Simba (all 3 colors), 9,840–18,200 ppm
Oberni, 17,600 ppm
Gulicola, 3,700 ppm
Lansinoh, 7,000 ppm, major brand, previously unflagged
Maymom, 3,300 ppm
Hands Free Baby Bottle, 22,300 ppm
Potato with Handles, 25,000 ppm, SKU-specific within an otherwise-clean brand
Matyz, Numvim, Fdbtl, Bobo, Natursutten, BIBS, Tommee Tippee, tested clean, no prior legacy advocacy work coverage
Pigeon copper / small-oz variants, clean, not previously distinguished from the leaded standard
Gentle Flow+ (post-recall), 51 ppm after $100k voluntary recall, an actual accountability story
NUK reformulated 2025, clean, directly contradicts her live 2021 avoid posts
What this approach adds:
Year-stamped data, not forever-blacklists. A brand that fixes its supply chain should move off the avoid list.
SKU-level granularity. "Pigeon" is not a single product. "Potato" is not a single product. This data separates them.
Leach testing as the disambiguator for trace-positive XRF results (the LifeFactory case).
Mechanism-level explanation for why a bottle reads positive, decorative paint frit, metal hardware, pigment choice, so a reader can reason about any untested product they encounter.

I was testing everything around the house like plates cups clothes etc, and most things were negative (yay!) But then i tested a pair of old boots and they came up positive!the pleather on the boots were flaking off too! My family would still be getting that exposure if i didnt have this kit, thank you!!
I am so glad I bought the Fluoro-Spec Test Kit! I've been worried about some of the dishes (especially mugs) my family regularly uses. I was able to reassure myself that most of the mugs were fine (one I did have to throw out due to testing positive for lead). And nearly all of our plates and bowls tested safe. I am thankful I have this to help make good, educated decisions about what items we use.
