2mL Autosampler Vials with Writing Area and Graduations, 9-425 HPLC, Screw Cap, Blue PTFE & White Silicone Pre-Slit Septa, 100 Pcs

We use these in place of buying from the manufacturer and they’re identical. It’s so much cheaper and works great for a GC application.

Excellent for what I've needed in the laboratory. Cap fits well. I place Kapton tape along the underside of the cap, in order to make it more resistant to volatile or corrosive solutions. These are well made and the caps hold on well, no issues to report whatsoever.

Might not be the intended use but indeed they are fantastic for DIY perfumers who experiment with different aromachemicals!

Work for what they were intended for. The printing on the outside of the vials came off when they were cleaned in an ultrasound bath but that wasn't a problem for my use.

The viles were fine I was able to heat things up in them they just don’t have the 2ml labeled but other than that they are good the tops are plastic so they will melt if heated too high!

I didn’t use them yet: but they meet the spec I needed, they fit the tray and dimensions I needed and they compare nicely to the more expensive ones from labware sites for way less.

Good product, specifications are correct, way cheaper than from chromatography companies

Seller was very kind and reached out to me regarding my concern that these were too small. If you are using these for lab purposes, they may work just fine. Seller graciously offered to send larger vials. Excellent experience with the seller.

El material es muy simple. Pero cumple con lo esperado.
