Spiral column is one of the most commonly used coiled column configuration. This 3D printed column provides a multi-level spiral configuration to minimise the differences in the aspect ratio of different coils. More information about the column can be obtained from the article published in Analytcial Chemistry (DOI: 10.1021/acs.analchem.7b03778)
 
The column can be customised with different channel I.D, the number of spirals, thread types, and print material. The current price is shown for the below-mentioned options:
 
Channel I.D: 1 mm
Column length: 30 cm
The number of spirals: two coils of aspect ratio 0.07 and 0.04 each on two different planes.
Threads: 1/4 UNF female threads.
Material: Polyacrylate composite
