Nylon syringe filter

Manufactured by PerkinElmer

Sourced in China

The Nylon syringe filter is a laboratory equipment designed to filter liquids. It features a nylon membrane that removes particulates from the sample, ensuring a clear and contaminant-free solution for further analysis or processing.

Quantifying Epicatechin in Freeze-Dried Samples

Check if the same lab product or an alternative is used in the 5 most similar protocols

Epicatechin was determined following the method used by Guetsky et al. (2005) , with some modifications. Freeze-dried samples (20 mg) were homogenised in methanol: water (1:1; v/v) solution. Thereafter, the Eppendorf tubes were centrifuged for 10 min at 14 000 x g. The supernatant was transferred to the new tubes, and subsequently filtered through a 0.45 μm membrane (Nylon syringe filter, PerkinElmer™, China) prior to injection. The analyses were carried out using a Flexar™ HPLC system (PerkinElmer, USA) consisting of a Flexar Isocratic LC Pump Platform and a variable wavelength Flexar UV/ ViS LC detector. Separation was done on an Analytical C18 column (100 x 4.6 mm; 5 μm) at 25 °C, using water/methanol (25:75 v/v) as a mobile phase, with a flow rate of 1 ml min -1 . Chromatographic peak of the epicatechin was identified by comparing the retention time with that of the pure epicatechin (HPLC grade) standard at 320 nm.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
