Borosilicate glass measuring vial — set of 4 Key benefits Built to last: borosilicate glass offers superior durability and resistance to thermal shock, so the vials hold up to temperature changes and regular handling. Accurate results every time: clear scale lines allow precise measurement and controlled dispensing for repeatable outcomes. Ready for practical use: available in transparent or brown finishes to match your needs; the brown option is suitable when reduced light exposure is preferred. Better value and convenience: sold in a set of 4 so you can measure, mix, or store multiple samples at once. What it does for you Eliminates guesswork when measuring small volumes, improving consistency for formulations, experiments, or recipes. Reduces breakage and thermal stress issues compared with ordinary glass, so you can work with heated or cooled samples with more confidence. Lets you organize projects or workflows by keeping separate samples in each vial. Compatibility and performance Material: borosilicate glass for chemical and thermal stability. Markings: integrated scale lines for precise measurement and dispensing. Colors: transparent for full visibility, brown for applications where reduced light exposure is desired. Pack size: set of 4 for flexibility and efficiency. Practical use scenarios Essential oil blending: measure and combine oils precisely to create consistent blends for personal care or testing. Laboratory sampling and small-volume dispensing: prepare and measure reagents, standards, or liquid samples for experiments and analyses. DIY formulations and crafts: accurately dose liquids for cosmetics, perfumes, inks, or small-batch production. What to expect Clear measurement markings to help you pour and transfer with control. Durable borosilicate construction that tolerates typical lab and craft handling. Four vials per set so you can run multiple tests or keep backups on hand.
