How to choose a lab coat
Updated: 21 October 2026
You have a course list or a workshop shift, and amazon.co.uk has answered lab coat with a 245 g work coat and a costume you can see through. How to choose a lab coat is a sequence, not a star sort. Take the rule you were given, then the hazard, then the cloth and the studs, and only then that brand’s size chart. A high star line does not turn a standard stud coat into a Howie coat. The [Lab coat comparison](/hub/occupational-safety/lab-coat) holds the twelve listings captured on 19 October 2026. Peter F. used those amazon.co.uk rows and public UK guidance, with no lab test. A qualifying purchase can earn a commission at no extra cost to you.

Start with the rule you were given
The first check is the sentence your department, school, or employer already wrote. University of Surrey tells bioscience students that a coat without a high neck, stretch ribbed cuffs, and an asymmetrical stud front is the wrong coat, and they are expected to buy another. University of Nottingham treats a standard V-neck as acceptable only for lower-hazard work, and a Howie coat as mandatory for biological and GM work. Edinburgh biological sciences practicals issue Howie coats. Edinburgh chemistry tells students to buy what that school specifies.
If your paper names Howie, flame-retardant cloth, or a containment level, stop looking for a clever reading of a marketplace title. None of the twelve listings states a Howie cut, EN 13034, or EN ISO 11612. The Howie lab coat vs standard page is that fork. If nobody named a cut, HSE’s COSHH guidance treats clothing as PPE only when it gives a specific protection. Otherwise it is workwear.
Match the hazard, not the word lab
Dust, dirt, and a small splash are a different job from a Bunsen, a solvent jet, or containment level 2 or 3. A reusable 65% polyester and 35% cotton coat is ordinary UK workwear. Nottingham’s guidance says that blend can melt. It is a poor choice beside a flame or a large solvent risk, even when the reviews are kind.
HSE’s clinical-laboratory guidance expects a protective coat or gown at containment level 2 and above, covering you standing and seated. At containment level 3 the preference is a side or back closure, close cuffs, a quick release, and a flame-retardant cloth that can be autoclaved. None of that is printed on these twelve titles. School practicals stay with the teacher and CLEAPSS. A GCSE afternoon with a Bunsen on the bench is not solved by a 65/35 coat you liked in a photograph.
Read cloth weight and fastenings
Read the cloth, not the word cotton in the title. Prefer a stated 65/35 blend at about 245 g/m², or a finished coat whose item weight sits around 400–600 g. Fabric weight is the cloth. Item weight is the finished coat. The Portwest 2852 states 245 g Kingsmill polycotton. Size L is listed at 570 g and size M at 530 g, both at about £16.64. Labmarc’s title states 200 GSM at about £14.95, with only 15 reviews. AIUNBEST states an item weight of 160 g at about £9.59, and a review quotes a label of 90% polyester and 10% spandex.
Fasten with studs you can pull open. Nottingham and HSE both want a quick release. A button you must unpick is the wrong front if something spills. OEKO-TEX on a title, including Yeats & Sterling at about £23.95, is a textile claim. It is not EN 13034. If the title says thin style, or reviews say you can see through it, read lab coat too thin before you pay.
Size from that brand
One size rule for every ASIN is wrong, because these listings do not share a block. AUYAO reviews say the coat runs small, and the advice ranges from one size up to three sizes up. Lab Coat X, at about £19.49 with a stated 40-inch length, runs the other way. A UK 16 and a partner in S/M both found medium and large huge, so the useful move there is to size down. Portwest reviews call the 2852 long, including for some people who usually take a medium, and they describe a male fit that is not cut for a woman’s hips.
Hawthorne is a women’s slim coat at 33 inches and about £26.95. A reviewer who usually wears a UK size 10 was happy in medium, and other notes say it can be tight. Meichoon states a 35/65 blend and a 300 g item weight at about £20.99, and it has no reviews. MF Professional is titled for women, with one review and a department field that says Girl’s. Do not infer an adult work size from that line.
When the rule is silent
If the rule is silent and the job is dirt or a low-hazard splash, shortlist the listing that names a 245 g polycotton stud coat, then check that brand’s chart against your usual size. If the rule says Howie or flame, leave this amazon set. Stars come after the cloth. A high score on a dress-up title is not a PPE result.
Common questions
What should I check before the star rating?
Check the written rule, then the hazard, then whether the listing states a cloth weight and a stud front. Surrey and Nottingham publish different cuts for different work, and a 4.5 does not override either page. In this set the Portwest 2852 is the coat that states 245 g Kingsmill polycotton. A thin-style title can still collect hundreds of reviews. Stars are the last sort, after the cloth matches the job.
Is a 65/35 polycotton coat enough for a school practical?
It can be ordinary cover when the teacher has asked for a coat and the hazard is low. It is not a flame coat. Nottingham notes that 65% polyester can melt, so a Bunsen on the bench is a reason to follow the school’s specified coat and CLEAPSS eye-protection rules. An amazon costume title is not that specification. If the practical sheet names a fabric or a supplier, buy that, not the closest white photograph.
When do I need a Howie coat instead?
You need one when the department or the containment rule names a high neck, ribbed or knitted cuffs, and a side, wrap, or asymmetrical stud front. Surrey bioscience practicals use that list. A normal centre-front stud coat fails it even if the cloth is thick. If your paper never mentions Howie, a standard coat can still be the brief for lower-hazard or workshop work.
How do I tell a costume coat from workwear on amazon.co.uk?
Look for a stated gram weight, the words thin style or fancy dress, and review language such as see-through. A 160 g item weight, or a label a reviewer quotes as mostly polyester and spandex, is not a 245 g/m² work cloth. Price alone is a weak test: Labmarc states 200 GSM at about £14.95, which is not the same product as the thin-style coat at about £8.49. Photographs hide the weave.
Why do some reviews say size up and others size down?
They are describing different coats. AUYAO reviews say size up, sometimes by more than one UK size. Lab Coat X reviews say the 40-inch coat runs very large, so those buyers size down. Portwest notes call the 2852 long and male-cut. Copying one reviewer’s rule onto another ASIN is how a medium arrives as a tent or as a coat you cannot close.
Does OEKO-TEX mean the coat is chemical PPE?
No. OEKO-TEX on a title is a textile claim about the cloth, not EN 13034, not EN ISO 11612, and not a Howie pattern. Yeats & Sterling carries that word at about £23.95, with 4.2 from 6 reviews and a note that it runs large. It does not become a splash barrier or a flame coat because the title includes the mark. If the assessment names a chemical suit, this set does not contain it.
What does a lab coat not replace?
It does not replace eye protection, a COSHH assessment, or a control that should happen before clothing. HSE treats PPE as a last resort that protects only the wearer. A coat also does not replace a glove, a face shield, or a ban on taking contaminated workwear home. If the department has named a standard the listing does not show, buy the specified coat from the supplier they name, or borrow the one they issue.
