Laboy Glass Advanced Chemistry Lab Glassware Kit 24/40 Glass Adapter Flask Condenser Funnel Stopper Joint Clip Distillation Apparatus (29pcs)

My other pieces from Laboy seem to have been high quality glass with no stress lines in the joints from cooling too fast or microbubbles. The grinding was smooth with no visible ring. They received the order and sent my set it a timely manner but it was lost in transit in China (sent to the wrong city). China's mail system seems to be struggling right now (01/2023). I was 2 months waiting for the set. I was refunded after a long wait. I bought all my set pieces from various manufacturers. My Laboy buchner filter came as advertised but it had a hole, presumably from shipping. I could see where something long and sharp went through the box and all packing layers and broke a hole in it. They are replacing it. I am waiting for the 'three ways' to come still. It is High quality if you can wait a while and risk customs and the mail system.

This is high-quality Chinese glassware comparable to some American brands that I also own, Pyrex, and Chemglass. It is precision boro 3.3 glassware thick walled as advertised.It is a great set but not complete, you will still have to buy a bunch of stuff, like thermometers, thermocouples, various adapters, filtering apparatus and filter papers, heating mantle, hot plate stirrer, retort stand and various clamps, addition funnels, solvent cold traps, vacuum pump, optional stuff like solvent still, Friedreich's condenser, shortpath distillation head with receiving cow and collection flasks... The list could go on, but you can see that this is not complete chemistry set, just the basic glassware.The Bad stuff:1 piece was missing from my set and i had to buy it off Amazon separately.The supplier does not respond to messages. And don't try ordering from their website as you will have to go through PayPal refund process months later when your order doesn't arrive, and no communication whatsoever. (As of Nov. 2021)

This is a pretty great set for the price. The glass is sound; I've performed half a dozen vacuum distillations with the kit and tried out almost every piece. No leaks and no signs of fatigue after several cycles at up to 140°C and down to -20°C at around 50 torr. I think most of the pieces should last quite a while as long as they are handled gently. Shipping took quite a while and several pieces were broken on arrival but within 24 hours of contacting the seller another shipment was on it's way with the replacement glass; this package was far speedier than the original order. I would recommend this product to anyone in need of a starter kit; the glass is not perfect but it works well and the seller will take care of any problems.

I was pleasantly surprised with the quality of this glassware, I wasn't expecting it to be so thick and heavy. Makes me feel more confident that something isn't going to explode on me at higher temperatures. All the joints fit together nicely and also fits well with pieces of glassware from other manufacturers so that is good. metal pieces aren't the best quality but that's not very important to me. It took a while to be shipped. I ordered early July and it did not ship and arrive until the end of August. So make sure to keep that in mind if you buy this set.

Thick glass good quality, well packed when arrived.

I love all the products but now I don’t have clips and your sold out and I’m right where I was before.

Love the product, glass is thick and heavy as advertised.

This set of glassware arrived all intact with all parts shown in the picture. The glassware is good and heavy, all parts fit together exactly as they should & also fit with all of the other brands of glass we already have just fine. The clips & clamps all work correctly. Nothing but good to be said for this order. Coming from China I received this set in one week.
