Company Description
Pawling Engineered Products is a vertically integrated business that designs and manufactures highly specialized elastomeric septa, seals, gaskets, and other unique rubber products for many different industries. Noted especially for innovation with pneumatic seals, ours is a history of challenging convention and solving tough problems with inventive yet thoroughly practical solutions.
Pawling has recently launched its new, patent pending ePFE™ elastomeric technology which combines the benefits of perfluoroelastomer (FFKM) with the dynamic properties of more traditional materials. Highly chemical resistant O-rings, flange, and coupling seals can be manufactured using this technology.

Pawling offers its complete Cepure line of injection port and autosampler septa, along with information on its new ePFE technology on the web at pawlingepd.com
Major Products/Services
ePFE™ seals — patent pending seal technology used to create highly chemical and temperature resistant elastomeric seals.
Zero™ Injection Port Septa — patented "no pierce" design increases septum life and reduces coring. The Zero has been tested to 1,000 injections at 400 °C inlet temperature and 60 psi pressure.
NT™ Autosampler Septa — low bleed, pigment-free septa to replace oft-used red/white septa types. Bleed analysis shows the NT to be over 60% cleaner when compared to other readily available septa on the market.
Custom Products — we welcome inquiries for custom formulations and products.

Influence of Concentration in Conventional GPC/SEC and Advanced Detection GPC/SEC
March 21st 2025Sample concentration is a parameter that can influence the quality of gel permeation chromatography/size-exclusion chromatography (GPC/SEC) separations and the obtained results. Understanding this influence can help to support the development of reliable GPC/SEC methods.
Multi-Step Preparative LC–MS Workflow for Peptide Purification
March 21st 2025This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.
