Topaz Inlet Liners by Restek Corp.

"We use this product to replace the part from the manufacturer in our GC. Saves us money without sacrificing quality."

"Topaz liners are the most reliable liners I have used. They are less expensive than other brands and are very inert. They give me confidence in my chromatography, especially because I always run something different everyday."

"Great packaging, easy to use, gives excellent results and separation. Keeps my machine healthy and is less likely to crack."

"Excellent liner for variety of testing on GC and GC/MS applications - I have used Restek liners for many years and have always been pleased with how robust they are with repeatable results. I have used them for testing pesticides and very pleased with stability and lack of breakdown in compounds. Packaging is convenient (I buy 5 packs) and have never received late orders of broken liners."

"Stable retention times even after large amounts of injections. Simple to manipulate, the direction of the text always determines the correct position. Attractive blue color"

"These liners are pre-assembled and very easy to use and install. My analysts appreciate the time savings."

"Highly recommend the Topaz Liner because this liner has the lowest levels of impurities, highest level of reproducibility from multiple injections and does not interact with the sample matrix. "

"The liners really do perform how the Restek literature describes. The peak shape has really improved for our methods. I wouldn't go back to our liners!"

"Product is easy to use. It works well with our equipment and we have not had any quality issues related to this product."

"We have found that the liners that we get our of the same quality as competetors but for a cheaper price, so it is a no brainer for us."

"Restek delivered our much-needed new inlet liners (along with their famous and fun Wizard Dollars!). The Topaz inlet liners were a replacement upgrade for the Sky liners we had before and fit the bill perfectly!"

"Really good liner, chromatography always good. Nice packaging and the blue color of the liner brightens the day!"

"The products actually delivers the results that are described in the literature provided by Restek. The products works well with Agilent instrumentation and it provides better peak shape than those purchased from Agilent."

"I replaced the old Skyliner PTV liner with the new Topaz PTV liner, and performed a quick "bake-out". Instantly the chromatograms looked clean and the breakdown was well below 5% for Endrin and DDT. When you only get up to 15%, any wiggle room will help. If a consumable can reduce reruns, we can maximize efficiency and turn-around-times. Thanks for your innovation. For a high-volume throughput lab it greatly eases my stress."

"The liners are overall really good. We usually get very uniform and reproducible results and installation is quick and easy. From time to time we will run into an abnormality and it does take some time for somebody to get back to us. For the amount of product we use I feel we should be able to get a better price."

"Great product, easy to change out. We used to clean old liners, but realized it was easier and more cost effective to buy new."

"These liners are quick and easy to install. They provide consistent results with less need for maintenance."

"A must have if you own a Topaz equipment. The inlet liners keep the inlet lines straight and durable. No longer do I worry about kinks and inlets being removed for any number of reasons! We had a faulty inlet liner before, but customer service replaced it right away even though it was a back-up liner that we had in storage."

"Have used Restek liners for a very long time. We have never had any problems."

"The Sky Deactivated GC inlet liners are a cost effective alternative to the expensive product from the OEM. The results were reproducible between batches of liners, making this a great value for the money. I do not worry about the validity of the results with these liners."

"Liners worked great for the three months I've had them."

"We ordered these to replace the skyliners, which we had been ordering for years and worked very well. In my opinion, the topaz liners need replaced more frequently for our applications. I probably will not order these liners again."

"Have used Restek liners for a very long time. We have never had any problems."

"The inlet liners help ensure I have sharp GC peaks with low background to enable the excellent separation of analytes in complex mixtures while allowing me to achieve low detection limits."

"Inlet liner for Shimadzu GCMS, fast shipping, quality performance, good value "

"Restek makes some of the best products on the market for my GCs. I have depended on them for over a decade to provide innovative products that are consistently reliable. I recommend them to everyone I know."

"Topaz inlet liners are incredibly easy to use, just like any inlet liner, but there's no question about the quality. I've not had any issues with active sites or analyte degradation in the inlet when working with thermally sensitive compounds."

"These are the best inlet liners on the market. They remain clean and inert longer than any other brand."

"Love these. Super easy to install and like that they are individually packaged. I just pop on out when I'm ready to change it. Love the wizard dollars program offered by this company too."
