UPDATE: The PolyLC materials PolyCAT A (cation exchange, the gold standard for hemoglobin analysis), PolyWAX LP (weak anion exchange) and PolyPROPYL A (hydrophobic interaction chromatography) are now available in 2-µm particle size, in addition to the usual range of columns in 3-µm and 5-µm particle sizes. At this stage, the 2-µm particle size materials are only available in pore sizes of 1000-Å or 1500-Å. However, alternative pore sizes could be prepared if there were sufficient demand. The 2-µm particle size materials have been demonstrated by customers to show significant improvement in resolution over the 3-µm materials. For further details, contact Chromatographic Technologies.
PolyLC Inc. has developed unique materials and methods for HPLC of proteins and peptides. The polypeptide-based coatings permit the resolution of many mixtures not possible with other methods. Poly LC Inc.'s product line includes columns and cartridges for Hydrophobic Interaction Chromatography, Hydrophilic Interaction Chromatography, cation exchange of peptides, selective removal of SDS from peptide digests, anion-exchange of proteins, and HPLC of complex carbohydrates. PolyLC Inc. can offer technical support for the most difficult biochemical separations. All of PolyLC's materials are available from Poly LC as Glygen's NuTips or TopTips.
Chromatographic Technologies is also an official distributor of Absolut A Protein A affinity columns for monoclonal antibody analysis, developed and manufactured in China by Wuxi Galak Chromatography Technology Co. Ltd. A range of agarose-based affinity chromatography media manufactured by Wuxi Galak are also available, including Sepromax A40 Plus Protein A, GLK-gel Protein A, GLK-gel Protein G, GLK-gel Ni and GLK-gel GST.

I have decided to use some space on my website to warn people about my experience with a company called Gearzii, who purport to sell outdoor and camping equipment. On 19.4.18, I placed an order to Gearzii, via their Facebook page, for 3 LED flashlights. My Visa card was processed the same day for the sum of USD 84.85. One week later, on 26.4.18, I received an email from Gearzii to say that my order was on the way. The email contained a link to a page where I could supposedly track my order, but the link was not functional. I emailed Gearzii to tell them this and did not receive any response from them. Since then, I have made repeated attempts to contact them, via email and via their Facebook page and via their website, but they have always either ignored me or responded by asking for information (which I provide and then they don´t answer, sending me back to square one every time).
So I have done some searching on the internet and have found this link and this link and this link which appear to indicate that this company is not to be trusted. According to the information provided in these links, if you order from Gearzii you will either (a) receive counterfeit goods or (b) receive poor quality goods or (c) receive nothing at all (as in my case).
The Gearzii website and store pretends to be located in the USA (Colorado or Arizona) but is apparently hosted in Canada (Ottawa) and the owner(s) location is in India (Jaipur). They claim to have warehouses worldwide but all their goods actually ship from China (if they ship out at all).
DON´T TRUST GEARZII.
