Customer Reviews
Good prices on PH meters, but hazmat shipping is tricky.
I was browsing for a new PH meter, specifically the HM Digital PH-200, and Chemical Warehouse had some of the most competitive prices I've seen, even beating out Lab Alley by about $23.40 on that particular model. I appreciate finding good value! My main concern, though, is their hazardous materials shipping. I was hoping to add some bulk chemicals to my order, but it seems there are significant restrictions and additional costs involved. It would be great if they offered clearer guidance or perhaps a flat-rate option for hazmat items for registered users, similar to how they handle discount codes for wholesale accounts. Overall, a solid choice for equipment, but less so for certain chemicals if you're trying to save on shipping.
Smooth experience for lab supplies
I needed some ACS grade chemicals for our lab, specifically hydrochloric acid and a new set of graduated cylinders. The ordering process on the website was straightforward, and I found all the relevant safety data sheets easily. Packaging for the hazardous materials was robust and clearly labeled, which I appreciate. Delivery took about five business days, which is standard for these types of supplies. Everything arrived intact and the quality of the chemicals was confirmed by our internal testing. Will definitely use them again for future lab needs.
Quick delivery, good product
Got my sulfuric acid and a beaker. Arrived quickly. Product was as expected. No issues.
Good value on first order
As a first-time buyer, I was looking for a good deal on some basic lab equipment. I purchased a magnetic stirrer and some flasks. The pricing seemed competitive, especially with a small first-order discount I found. The items arrived well-packed and seem sturdy. I felt like I got good value for what I paid. It was a worthwhile purchase.
Decent chemicals, long wait
I bought a bulk order of acetone and some nitrile gloves. The product quality was excellent, exactly as described for industrial use. However, shipping took a bit longer than I expected, even for a larger order. It wasn't a huge deal, but something to keep in mind if you're on a tight schedule. Prices were fair though.
Good for my home projects
I ordered some isopropyl alcohol and deionized water for a few things around the house. It arrived pretty fast, earlier than I thought it would. Everything was packaged well, no leaks or anything. Just what I needed, really easy process overall.
Perfect for my business!
I just got a large shipment of industrial degreasers and some PH adjusters for my business, and I'm so happy with everything! The quality is top-notch, and the bulk pricing was fantastic. It's exactly what I needed to keep things running smoothly. This store is going to be my go-to for sure!
