Insight of Hawach Sample Vial

Hawach tubes and sample vials are 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 supplies standard-certified automatic vials, caps, and septa at no additional cost. Within three types, screw top, crimp top, and 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, and 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 or material.

The cover gasket of the sample vial:
Threaded lid gasket: Gasket material: PTFE / silicone / PTFE, PTFE / silicone, PTFE cover color: black-8mm; blue-9mm
Mat color: white-silicone; red / blue-PTFE; blue is pre-opened
Jaw lid gasket: (The jaw seal is better, and more commonly used in GC injections, or long-term sample storage)
11mm silver-aluminum crimp cap and 1mm PTFE / silicone / PTFE diaphragm Color of mat: white-silicone; red / blue-PTFE; blue is pre-opened.

Advantages of Sample Vial
Hawach sample vial has excellent chemical stability, sealing and corrosion resistance, colorless and brown optional. This series of products are designed and produced in accordance with the requirements of EPA in the United States. The gasket uses the highest quality material to ensure its good function, in the storage process to ensure that the gasket will not fall into the sample bottle.

Moreover, the bottle cap of the storage series is made of high-quality polypropylene, which combines innovation with time-saving. This kind of chemical inertia bottle cap produced by the patented method really combines the gasket and plastic cap at the molecular level, which can avoid excessive evaporation and keep the sample bottle properly sealed.

Design Characteristic of Sample Vial
Hawach sample vial has a diagonal edge design to ensure that the bottle mouth and gasket can be better sealed before. The unique bottle mouth design ensures the sealing of the batch, the high precision processing technology, the strict quality control, and the size between the batches. Additionally, the gasket is made of polytetrafluoroethylene and high-quality silica gel as raw materials, which ensures that the gasket is non-toxic and effectively prevents puncture chip drop, which meets the requirements of chromatographic analysis.
