Each 8 oz plastic bottle (250ml) is precision-molded from laboratory-grade polypropylene, providing a durable, shatter-resistant alternative to glass for handling reagents, solvents, and sensitive specimens. Leak-proof seal for secure transport: Integrated seal rings in each screw cap create a reliable closure that prevents spills during transfer and storage, making these liquid containers dependable for both bench work and field sample collection. Autoclavable construction: Bottles and caps withstand sterilization at 121°C and perform across a full range from -40°C to 121°C, supporting standard laboratory decontamination protocols without degradation. Wide mouth design for ease of use: The large-diameter opening simplifies filling, dispensing, and cleaning - whether handling powders, viscous liquids, or aqueous solutions. Reduces spillage during reagent transfers. Broad chemical resistance: Polypropylene construction resists most corrosives, reactive materials, and common laboratory reagents, making these small plastic bottles with lids suitable for a wide range of storage applications. BPA-free, phthalate-free, RoHS compliant: Heavy metal-free materials meet safety standards for laboratory and educational use, with uniform wall thickness for consistent performance across the full pack of 12. Each bottle features a 43-415 cap thread, 33mm neck inner diameter, and compatible cap included - eliminating the need to source closures separately. The 8 oz plastic bottles with caps are supplied as a pack of 12 uniform units, supporting organized storage and sample tracking in research and educational settings. United Scientific™ reagent bottles are well-suited for university labs, high school science programs, and professional research environments requiring dependable plastic liquid containers. The combination of autoclavability, chemical resistance, and leak-proof closures makes this set a practical choice for educators and lab professionals managing multiple samples simultaneously. ## Features - LABORATORY-GRADE MATERIAL: Made from polypropylene, these 8 oz plastic bottles with lids resist a wide range of reactive materials and solvents, offering a durable alternative to glass.

It didn't break or leak or come loose when I dropped it. ### ⭐⭐⭐⭐⭐ Food grade, rigid / sturdy, roughly built but good value *by on Reviewed in the United States February 20, 2025* Note: this bottle is made of food-grade plastic. The product info on Amazon doesn't mention it, but you can find a statement saying so on the company's website. I use it for mixing and storing meal replacement drinks, and it seems to work well so far.Comparing this (4L polypropylene bottle) to a Nalgene brand 2L high-density polyethylene bottle I own, it find the material to be sturdier / more rigid, which could be a good or a bad thing. It's not as smoothly machined as the Nalgene bottle - you can easily see and even feel the seams in the plastic where edges of plastic sheets were joined together.The Nalgene bottle's cap is a single piece of plastic that screws on with a snug fit, whereas this bottle's cap is not as perfectly fitted and comes with a rubber ring inside to ensure it seals properly. The rubber ring needs to be removed and washed separately, which is an extra hassle compared to the Nalgene bottle. Perhaps it's inevitable due to the materials, though; it may be that this bottle's rigidity makes it harder to get a good seal without a rubber ring, whereas the Nalgene bottle is more pliable, allowing its cap to "bite into" the lip a bit.The rigidity also means that if the pressure in the bottle changes (e.g. if you put in a hot liquid, close it, and let it cool), it can be difficult to wrestle the cap open again, so watch out for that.Other reviewers have mentioned this, but the bottle doesn't come with any "United Scientific" branding on it. Instead, it has "PolyLab" and "4000mL" embossed on the bottom. I don't think that means it's counterfeit - if you look up import records, PolyLab appears to be an Indian company that serves as a supplier / manufacturer for United Scientific, so I wouldn't be too worried.Other than those points, I'm generally pretty happy with this bottle. It's twice as large as my Nalgene 2L bottle but costs significantly less, and works about as well for my purposes. (Actually better, thanks to the size.)EDIT: 6 MONTH UPDATEI'm still very happy with this bottle. No issues have come to light over the last six months that I hadn't already covered in my initial review. It works great and is a good value. ### ⭐⭐⭐⭐⭐ Liter six pack, solid, light almost indefinitely reusable *by on Reviewed in the United States April 23, 2026* As a medium to long distance dog walker I carry up to five of these full in my backpack daily. Full liter volume, tight lid, tough and light weight make them ideal for what I use them for. I can take my pack off and drop it to the ground without damaging these containers.These are dishwasher safe and BPA free.The dogs and I drink out of these almost every day.As I bought six and carry five the last one is kept 3/4 full in the freezer as an ice pack/water source for small coolers. ## Frequently Bought Together - United Scientific® Unistore™ - Sample Containers with Lids - Laboratory Grade Polypropylene Wide Mouth Reagent Bottle - 8 Oz Bottles with Caps (250ml), Plastic Bottles with Lids, Pack of 12 - Stainless Steel High Precision Forceps with Fine Strong Straight Serrated Point to use Engineer Labware for Scientific Use, (8 Inch) - FOUR E'S SCIENTIFIC 1mL Pipette Tips - Universal 1000ul Sterile Pipette Tips Racked Non-pyrogenic DNAse/RNAse Free Autoclavable 1 Rack 96 Tips --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/21922388-united-scientific-sample-bottles-with-lids-polypropylene-250ml-12-pack](https://www.desertcart.dk/products/21922388-united-scientific-sample-bottles-with-lids-polypropylene-250ml-12-pack) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-08-28*
