Check 9mm Screw Closures Quality and Weight

Aijiren uses PP Boxes for packaging. Generally, Aijiren uses 100pcs/pack, and the box has strong anti-impact ability. It is not easy to cause the vial to break during transportation. Aijiren’s 2ml hplc Vial has three different calibers to choose from. Screw, crimp and snap, the openings are divided into 8mm-11mm, many types are convenient for customers to choose.

But for autosamplers with blunt autosampler needles, Aijiren still recommends buying septa with pre-slit, because this can prevent the septa from being pushed into the vial by the autosampler and contaminate the sample. Septa with pre-slit can complete the function of guiding the automatic injection needle.

24mm Silicone/PTFE Septa is matched with 24mm screw neck cap, suitable for 24mm screw sample storage vial. Aijiren has an exclusive production technology that can compound PTFE and Silicone without adding any adhesives, so Aijiren’s Septa is soft and not easily deformed.

The 24mm Screw Cap produced by Aijiren is often paired with 24mm Sample Storage Vial. This type of Vial is used to store samples and sometimes used in autosamplers. For example, 40ml Vial is often called EPA Vial, and the center hole on the Cap is here. It will be useful in time, the sampling tool can easily pierce through the septa for sampling without causing sample contamination.

There are two types of 24mm Screw neck Cap, center hole and closed-top. The cap with center hole can be more convenient for sample injection. The closed top can store samples and has better sealing. It can have its own for 20ml-60ml. Storage range and capacity.

Aijiren’s 4ml threaded sample bottle (13-425) should be matched with 13mm Screw Closures, suitable for Aijiren, Waters, Varian, Shimadzu, PE, Diane and other types of chromatographic autosamplers. The 13mm Screw Closures produced by Aijiren have accurate thread sizes, and the width of the center hole ensures accurate collection by the autosampler. The 4ml transparent screw cap sample bottle (13-425) equipped with 13mm Screw Closures can also be used as a sample bottle and storage bottle.

13mm Screw Neck Closures are made of high-quality polypropylene. The thread shape inside the Cap can fit the automatic sample injection via very well, and it is also compatible with the automatic sampler. The 13mm Screw Neck Closures pre-assembled septum can reduce the chance of contamination during sample preparation and save time in laboratory sample preparation. Aijiren provides septa and slit septa. The normal available cap color is black, but other special colors can also be produced.

The worker of Aijiren shown in the picture is inserting a 22mm Silicone/PTFE Septa into a 24mm Screw neck Cap. The worker wears finger cots and holds a tool to press harder to consolidate the tightness of the Cap and Septa. Since Aijiren’s automated merging of Cap and Septa machines is only suitable for the closure of 2ml autosampler vial, this large-volume closure requires manual combination by workers. Aijiren uses a dust-free workshop for production and packaging, so customers can be completely assured of hygiene issues.

The Headspace Vials produced by Aijiren have two different calibers, one is Crimp Neck and the other is Screw Neck.
