Aijiren Tech Scientific offers the vials you need for all of your laboratory requirements and applications. Whether your needs include chromatography, sample storage, cryo-preservation or scintillation, we have options for you.

Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including

Pozi Compatible ST Green Anti-Corrosion Decking Screws. These Single Threaded Decking Screws are compatible with our Timber Decking for quick and easy installation. The screws are treated to be resistant to corrosion and are hardened for a stable and durable installation and the design of the screw helps prevent splitting of the boards.

Apr 15, 2019 · Microbiologically influenced corrosion (MIC) of carbon steel by sulfate reducing bacterium (SRB) Desulfovibrio vulgaris under organic carbon starvation was investigated using electrochemical methods to support weight loss and pitting data. 20% carbon source led to the highest weight loss (6.6 mg/cm 2), while 100% had the lowest (3.3 mg/cm 2) after 10 days.

Solid or liquid samples are sealed in headspace vials. Water or a high-boiling organic solvent may be added to the vial to dissolve the sample and facilitate release of volatile compounds to the gas phase. The headspace vials are typically heated to drive partitioning of volatiles from the solid or liquid phase into the gas phase.

Jun 01, 2020 · With the increase of the headspace volume, R p increased, indicating increased corrosion resistance (i.e., decreased corrosion rate) for a larger headspace volume. The lowest R p (149 Ω cm 2) was found in the vial with 10 mL headspace on the 1st day while the highest R p (328 Ω cm 2) in the vial with 160 mL headspace on the 5th day.

Dec 01, 2020 · This 1 mL inoculum and 3 coupons reduced the headspace volume in each 125 mL vial from 25 mL to 23 mL. The initial planktonic cell concentration right after inoculation was about 10 5 −10 6 cells/mL. All the vials were wrapped with aluminum foil to block light to protect photoactive riboflavin before they were incubated at 37 °C for 7 days.

The headspace sample bottle is a kind of laboratory sample bottle used for headspace analysis, which has the characteristics of high temperature resistance and corrosion resistance. Headspace gas chromatographs use headspace vials. When detecting a volatile or semi-volatile mixture with a high boiling point, we need to heat it to evaporate the top.

Headspace sampling of H 2 was followed by gas chromatography (GC). Mycelia (0.3 g) were homogenized for 1 min, placed in a vial, and then 7 mL ddH 2 O, 5 mL octanol (purity 99%), and 0.5 mL sulfuric acid (5 M, purity 99.9%) were added. Afterward, nitrogen gas was added to the vial to replace the air.
