When the number of samples to be tested and the need to use an autosampler, the capacity of 2ml HPLC Vial is a bit too large, then we need Micro-insert, which is a very cost-effective solution. Most autosamplers have a set depth, the autosample needle is inserted into the HPLC Vial without touching the bottom, Micro-insert can deepen the depth of the sample, and the small number of dozens of samples can be completed.
What should we consider when selecting the HPLC/GC vial insert? Aijiren offers three types of HPLC Vials Micro-insert. To choose the right HPLC Vials Micro-insert for your needs. The flat-bottomed Micro-insert has the largest capacity, the bottom is flat and cylindrical.Conical glass inserts have a tapered bottom, which has a smaller micro-insert capacity than the flat-bottomed, resulting in higher recovery rates for samples. 
Micro-insert with Mandrel Interior and Polymer Feet's feet can hold Micro-insert. It also makes the HPLC Vials a stronger seal.Aijiren offers three types of HPLC Vials Micro-insert.
