Chromatography Vials from Aijiren

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. Headspace sample vial is generally used for gas phase experiments.

The headspace sample bottles produced by Aijiren can be made of clear or amber glass, with round or flat bases, crimp seals with beveled or square edges, or surface treatments with threads. The headspace bottle, septum and cap can be purchased separately or together as a convenience kit to meet the needs of your laboratory.

Although most laboratories have switched to 9 mm screw thread vials for a wider opening while still being autosampler compatible, some labs use 8-425 vials for storing solvents. The standard opening 8-425 vials have more threads per inch, so there is less likelihood that volatile solvents will evaporate over time.

COD Test Tube is one of Aijiren’s main products. It can complete many important experiments, such as digestion colorimetry, water quality test, oxygen demand test, etc. The COD Test Tube produced by Aijiren has high inertness, good quality and stable tube. Aijiren has become a well-known manufacturer of chromatography consumables in southern China by virtue of the good quality of COD Test Tube.

10/20 mL screw neck headspace vial is a type of laboratory container commonly used in analytical chemistry and pharmaceutical applications.
It is specifically designed for the analysis of volatile compounds in a sample using a technique called headspace analysis.
The vial features a screw neck, which means it has a threaded opening that allows for a secure closure using a cap or septum.
The screw neck design ensures a tight seal, preventing any leakage of the sample or the escape of volatile compounds during analysis.

The 2ml snap HPLC vial is made of type 1 borosilicate glass. Compared to 9mm screw vials, this 2ml snap hplc vial opening is a wider opening. Therefore, the 2ml snap top HPLC vial is easy to fill and increases the target area of the autosampler needle. This means that 2ml snap-top HPLC vials can protect needles.

The 2ml snap-top HPLC vial size is 11.6x32mm and is compatible with most autosamplers such as Aijiren. 2ml HPLC vials are available in amber and transparent colors. The bottom of the vial is flat. It is convenient to put. Aijiren offers 2ml snap-top HPLC vials and pads at wholesale prices.

Hydrophilic nylon membranes have extremely low levels of extractables and contain no wetting agents. They offer good chemical resistance and are ideal for aqueous and most organic samples. Filters are Triton-free and have a bidirectional membrane support and luer lock inlet/outlet for a secure fit to the syringe. Membrane type and pore size are printed on each filter for easy identification. All Cole-Parmer syringe filters are 100% integrity tested and manufactured in accordance with ISO 9002 standards. Sterile filters are sterilized by gamma radiation. They are certified nonpyrogenic, noncytotoxic, and are blister packed.

Micro Insert is used to ensure the most accurate and reliable analysis of your lab samples. 250ul 300ul vial inserts can be used for 9mm, 10mm, 11mm vials.

Universally compatible on almost all autosamplers, thereby rationalization of other 1.5ml vials, as for instance 11mm Crimp Neck Vials, Screw Neck Vials 8-425 and 10-425, is possible
Vials with integrated Micro-Insert are available in amber glass

Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer’s specifications. Aijiren Tech vials are available in 6ml, 10ml, 20ml versions with Screw and Crimp type.

More convenient, consistent, and safer sealing process compared to crimping (better reproducibility). No risk of inaccurate or inconsistent crimping results. Due to thinner septa suitable for SPME as well as for Headspace. Often used on CTC Combi PAL and identically constructed autosamplers as well as on Perkin Elmer instruments.
Aijiren supply ND18 screw headspace vial in wholesale price, welcome to inquiry. You can also find Aijiren by those channel.

All Aijiren bottles have permanent white enamel scales for volume measurement; white identification boxes for marking or coding.
All Aijiren media bottles include non-drip sealing rings and standard blue polypropylene (GL45) sealing caps.

Features:
1. It is made of borosilicate 3.3 glass, which has the properties of chemical resistance, heat resistance and impact resistance. The unique design of the pouring ring at the mouth of the bottle avoids dripping during use.
2. For the convenience of use, reagent bottles with a capacity of 100ml and above all adopt uniform and replaceable screw caps and pouring rings.
3. The bottle body, bottle cap and pouring ring can be sterilized by high temperature and high pressure.
4. Suitable for sample collection for various liquid particle size testing, containing high-clean reagents, standard materials, and standard samples
5. Threaded bottle cap with good sealing performance, which can effectively isolate external magazines, dust and moisture
6. The specifications are clearly marked and the volume scale is obvious

Compressed sterile air filters can be used to create clean rooms free of bacteria and other harmful particles for people with compromised immune systems. Each air supply pump is also equipped with a sterile air filter to ensure the delivery of pollution-free air. These air filters are usually sterilized by gamma rays and packaged separately.

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.

Polyvinylidene difluoride (PVDF):?designed for high tensile strength, high solvent resistance, and low protein binding, making them suitable for biomedical filtration, sterilization filtration, and HPLC sample preparation. pH range ~1-14.
