1. I-V Meter for Characterizing Materials and Devices
Since 2006, we have been producing I-V meters (Fig. 1) used to characterize electrically materials as well as devices. The I-V meters have been spreading from Sumatera to Sulawesi Island along with the alumni who returned to their home towns.

2. Electrospinning System for Synthesizing Nanofibers
In 2014, we have been providing electrospinning systems (Fig. 2) for researchers and professionals who want to obtain various nanofibers for diverse applications such as membranes, filters, matrices, and tissues. The first shipping was carried out in May 2014 to Prof. Heru Susanto of Chemical Engineering Department, Diponegoro University, Semarang, Indonesia. The second one was to Prof. Amun Amri of Chemical Engineering Department, Riau University, Indonesia in September 2015. The third one was to Mr. Mulyana Ahmad, who is an independent researcher in Bogor in September 2015. Currently, other universities that have them are ITB (Prof. Muhammad Ali Zulfikar), Universitas Sriwijaya (Prof. Ida Sriyanti), dan Universitas Udayana (Prof. Ni Nyoman Rupiasih).
