OEM/ODM foe SPE

We provide empty column tubes and frits sets, which are made of polypropylene. 

The frits plays a role in fixing the packing and controlling the flow rate in the solid phase extraction column.

Customers can choose to buy it by themselves, so that you can fill the packing you need.

You can also choose us as your OEM / ODM. We have mature assembly technology and competitive cost performance, 

and can provide you with stable, reliable and high-performance product solutions.

If you choose to fill it yourself, give you a few tips

1. we recommends that the pore size of frits should be smaller than 1/2 of the particle size of filler/sorbent used. For example, 

for packing/sorbent with a particle size larger than 40um, frits with a pore size of 20um are recommended.

2.The frits is made of ultra high molecular weight polyethylene at one time. Impact resistance/ excellent wearability/ chemical corrosion resistance

 (acid, alkali, salt) and organic solvents (except naphthalene solvents). Divided into hydrophobicity and hydrophilicity, 

if the solution is an organic solvent, a hydrophobic frits is generally used; if the solution is an aqueous phase, a hydrophilic frits is generally used.

*Our frits diameter, thickness and aperture can be customized
