Hawach tubes and sample vials are the essential devices for collecting, transporting and storing samples. Always available in a variety of colors, sizes, volume capacities, and material compositions, Hawach sample vials can make your lab much more efficient with fewer failed assays and make instrument lifetime longer by avoiding vials out of specification.
To prevent contamination, Hawach sample vials are well prepared for toxicity tests with clear, white, or amber vials for ultraviolet sensitive samples. Ready for immediate testing for accurate results, open-top, closed-top, attached, or screw-on cap options permit quick access to contents in your lab.
Hawach sample vials are made from USP1 and Borosilicate glass. The good quality of the glass can ensure you can achieve consistent and reliable analytical results all the time. You can find Hawach supply standard-certified automatic vials, caps and septa at no additional cost. Within three types, screw top, crimp top, snap top, all of the Hawach vials are guaranteed to work in your auto-sampler and bring high quality with affordable most to you.
Sample vial category: Bottle mouth type: thread, snap, jaw (where the jaws need to be matched with pliers); from color: transparent, brown (brown is mainly used to protect from light); 40ml
From the caliber: 8mm, 9mm (8-425 / 9-425 standard are threaded), 11mm is the jaw/bayonet;
From writing space: with or without writing space;
From the glass material: USP1 borosilicate glass (compared to domestic glass bottles is more expensive), the transparent color is divided into 7.0 and 5.0, 5.0 is better, the transparent glass is all USP1. Therefore, when choosing a bottle, the customer mainly chooses from the bottle mouth type, color, volume, caliber, whether with writing and material.
