Regular array using 50 um wire that is suitable for most experiments. However, we also offer arrays with 25 um wire. Since the transverse areas of the 25 um wire is only 1/4 of the 50 um wire. The inserting force is significantly reduced. Therefore, it is better choice for some experiments that need high-density arrays (200-350 um spacing).
Similar to 50 um arrays, 25 um arrays have all the same process like sharpening, tip hardening, and biocompatible coating.
Both conventional and our modular connectors can be used to make 25 um wire, depending on your need. However, 25um array are much harder to make. Therefore, it is more expensive than regular arrays. For normal density arrays (400+ um spacing), the 50 um wire is still the better choice.
Right panel figure shows a 25 um array mounted on our modular connector.
