These were from a laboratory closure overstock, these were stored in a climate controlled area along with other lab equipment. The column is unused and appears in good condition. Based on some of the dates on some of the items these are probably 7-10 years old. Sold as-is as shown as I am not an expert and don’t know if these are still viable but they were stored at controlled temperatures and are unopened still manufacturer sealed. Based on my research these should still be viable. They are sold at a fraction of the cost as compared to the manufacturer, open to bundles and offers.
