Zhejiang Aijiren, Inc. products

9mm screw thread vials are designed especially for use with Agilent`s and other rotating or robotic arm samplers 2ml, 12X32mm vials are manufactured of borosilicate glass and include a write-in patch for sample identification. Caps are made of high quality polyproylene to exact manufacturing tolerances and lined in a controlled manufacturing environment. Available cap colors include yellow, red,green and blue.  Our septa use only the highest quality materials to ensure proper function and can be pre-slit to ease needle penetration. Designed for single injection and/or short sample cycles, particularly for LC applications. Absence of elastomer layer reduces potential for contamination.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. One piece polypropylene cap and membrane are also available. These pierceable screw thread caps are designed for one time use and reduce sample preparation time as there is no cap and seal to assemble. Screw Cap Vials are universal. Screwing the cap applies a mechanical force that squeezes the septum between the glass rim and the cap. Screw caps form an excellent seal and mechanically hold the septum in place during piercing. No tools are required for assembly.

Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called an autosampler vial. And this sample vial is extremely compatible.The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijirenscrew thread top vialsis developed from Europe and the United States, and the design feature is easy to use, especially the use of an automated sample introduction system.

Aijiren Technology, a reputable manufacturer based in Zhejiang, specializes in laboratory consumables. They offer 18mm Screw Thread Headspace Vials designed for use with a variety of autosamplers, including Shimadzu, Varian, and others. These vials are made from USP Type 1, Class A, 33 Borosilicate Glass, ensuring high resistance to chemical corrosion and temperature fluctuations between -60°C and 200°C. The vials are supplied with magnetic precision screw-thread metal caps and PTFE/silicone septa that ensure optimal sealing and minimal evaporation. The rounded bottom design provides increased resistance to high pressures during heating processes. This makes them particularly suited for GC systems where precise sample containment is crucial. Available in clear or amber glass with a volume range of 10-20ml, they are ideal for various analytical applications, emphasizing dependability and efficiency in laboratory workflows.

Zhejiang Aijiren offers 16mm test tubes specifically designed for water analysis. Made from USP Type 1, Class A, 33 borosilicate glass, these test tubes provide high resistance to thermal shock and chemical attack, making them ideal for precise laboratory applications. Each tube has a round bottom and a neck diameter of 16mm, with overall dimensions of 16 x 100mm, and a volume capacity of 12ml. They are available in packs of 25 or 100, catering to different sample analysis volumes and frequencies. The test tubes come with a PTFE septa for secure sealing and White Screw Polycarbonate caps to ensure the sample's integrity during analysis. Offered at competitive prices, these quality laboratory consumables are suitable for stringent laboratory environments, providing reliability and accuracy in water quality testing.

The 40mL TOC Vial, primarily used for environmental and laboratory analysis, features a neck with a 24-400 screw design allowing for secure closure with PP caps and septa. Constructed from high-quality borosilicate glass, these vials offer chemical resistance and thermal stability, ensuring sample integrity during storage and transport. The vial has dimensions of 27.5mm by 95mm and is available in both clear and amber for light sensitivity considerations. It is suitable for various analytical applications due to its compatibility with stringent testing environments. These vials are supplied in packs of 100 pieces with a minimum order quantity of one pack, facilitating bulk application requirements in laboratory settings. Additionally, due to its durable glass material—USP Type 1, Class A, 33 borosilicate—it is ideal for long-term sample preservation in diverse environmental conditions.

HPLC syringe filters are essential tools in laboratory settings, specifically designed to aid in the purification of samples prior to high-performance liquid chromatography (HPLC) analysis. Manufactured from various materials such as Nylon, Hydrophilic PVDF, Hydrophilic PTFE, Hydrophobic PTFE, PES, MCE, Hydrophilic PP, and Cellulose Acetate (CA), these filters ensure compatibility with a wide range of solvents and samples. Each pack contains 100 filters, optimizing filtration processes by removing particulates that can clog HPLC columns, thus ensuring reliability and accuracy. The filters are suitable for diverse filtration applications and demand careful consideration of material compatibility in experimental setups. The filters are engineered to facilitate optimal flow rates and particulate retention, playing a crucial role in maintaining the integrity and performance of analytical instrumentation.
