At Chrom Tech, we supply a large selection of essential lab supplies. In fact, one of our most popular products is our 11 mm wide mouth glass vials with a crimp top. These vials offer a 40% larger opening, allowing for easy pipetting without sacrificing autosampler compatibility. In addition to our wide mouth glass vials with crimp tops, we also offer crimp caps. These crimp caps offer our best seal for volatile compounds and eliminate the fear of evaporation with solvents used in gas chromatography applications. If you have any questions about our vials, caps, or any of our other products, please reach out to our experts.
