Filters

Purity in every sample

Membrane separation technology is one of the most advanced and efficient, allowing the
purification, separation, and concentration of liquids and gases without phase changes or secondary
contamination. Its use in laboratories offers a cost-effective and energy-efficient alternative
compared to traditional methods.

Syringe filters

PQN Essentials syringe filters are available in different sizes and

membrane configurations, both in sterile and non-sterile versions,
adapting to various needs in the laboratory.
