CRS demands a certain level of quality in our products and our ZPure Ultra Purifiers surpass even that by bringing a new set of features to the line. The ZPure Ultra Purifiers are designed for use when extremely pure gas and leak protection is critical to the application; such as in the microelelctronics and semiconductors industry. These high-quality filters are constructed of 316 stainless steel for maximum purity with an electropolished surface finish. They contain a 0.003 μm outlet particle filter, have long lifetimes, and can reach outlet purity to the ppb levels. The ZPure Ultra Purifiers come standard with 1/4” metal gasket seal fittings for superior leak ratings.

CRS has several types of coating and surface treatments available for various materials. Coatings include a glass barrier coating, hydrophobic barrier coating, low bind coating, diamond coating, non-stick, low friction coatings, and more. These are just a few of our capabilities. Contact us regarding your application to see if we have an offering to fit your needs!

CRS can purify hydrogen gas down to ppb levels. The Infinity Hydrogen Gas Purifier is a self regenerating purifier that removes oxygen from hydrogen at ambient temperature. The catalytic reaction consumes the oxygen and creates water vapor. When paired with an additional moisture filter, it is the perfect solution for hydrogen generators. The catalyst can last indefinitely if not contaminated. Questions? Contact us to see if this could work in your application.

Glass Coated Well Plates? Sure, these glass coated well plates have been on the market for some time, but CRS has now developed our own line. We believe our Pure-Pass brand matches the quality of current offerings at a competitive price point. CRS Pure-Pass Well Plates are offered in the basic uncoated ultra-clean polypropylene plates, as well as the premium glass coated plates that provide additional barrier protections for those specific applications such as in bioanalysis or pharmaceutical sampling. The polar surface of the glass coating has been shown to substantially reduces the risk of adsorption.

Found yourself searching online for our products and come across a price that seems too good to be true? If it seems lower than what you would expect, you might want to do a little digging before making that purchase. It could be a knock off product of the brand you trust. We all know the saying “you get what you pay for” and it never hurts to do a little extra checking.

CRS prides itself on developing a more ergonomic work environment. We practice this through the products we manufacture for our customers as well as the way we work in our own office and warehouse! Our hand crimpers are superstars at demonstrating this. They are made of a much more ergonomic casing- it is smaller, more lightweight, and yet still touch enough to get the job done. The Glass-filled plastic body with reinforced handle conforms to the natural shape of your hand.

The AFS has long been one of our flag ship gas purifier products here at CRS. It has remarkable lifetimes that wipe out the competition, with the combined benefit of the site glass for moisture and oxygen indicators. The only potential downfall that we repeatedly run into with end users was its “hazardous” shipping status. The media used in the AFS that allows for these extremely long lifetimes is also its downfall for end users that aren’t set up for receiving these special items, or want to deal with the extra cost associated with a hazardous shipping program.

At CRS, we have a wide range of options to purify your laboratory gases. We understand it can be overwhelming to narrow down which is the right one for your application. Never fear, we are always available for technical support and with the right information, we can help make the best recommendation for you. We typically have a set of questions to help us narrow down the options. The purity level of your source gas, and your flow and pressure ratings can drastically affect how long any given filter will last for your specific application.

Chromatography Research Supplies (CRS) has developed a moisture filter specifically targeted to SFC end-users in petrochemical analysis using carbon dioxide as their mobile phase. In this specific application, the adsorption properties of the typical 5A or 13X molecular sieve media can cause rapid heating of the purifier cylinders from CO2 adsorption as well as the intended H2O molecules. With the CRS 3A molecular sieve filter, the smaller pore size allows for the removal of moisture while excluding almost all larger molecules, including the CO2 being used as the carrier.

We often get questions asking for lifetime estimates on filters. While we make our specifications conservative to try and get 1 year of life out of each filter from an "average" application; the truth is, this estimate can vary drastically based on the conditions of your application. To get a true estimate we have to collect some data pieces from you first! With our new form, you can easily gather the information needed and input it into the form. You are guaranteed to hear back from one of our team members by the next business day. Check it out...
