SunShell 2.6 um, 5 um column tubes use IDEX Isobar column hardware. Currently, some IDEX Isobar column hardware takes more than 6 months to be delivered. For sizes that are out of stock due to late delivery, we will use domestically produced column hardware in parallel. We have confirmed that the performance of domestically produced column hardware is comparable to that of Isober column hardware.
Thank you for your understanding.
