Electric soldering iron: Needless to say, it is mainly used to weld components, and sometimes used to iron silicone or plastic. According to the position of the heating element, the electric soldering iron has an external heat type and an internal heat type. There are also electric soldering irons with tin absorption function.

Heat shrink bushing: used to insulate and bandage cables.
The chip inspection will be performed using PromethION software. This process mainly tests how many nanopores are available in each chip. After receiving the chip, the chip should be inspected within 5 days to replace the faulty chip in time, and then it can be stored at 4 °C. If it is not used for a long time after inspection, the chip must be inspected again before the library preparation.

operating principle
< br >
During chip quality inspection, QC DNA molecules stored in the chip buffer can produce specific signals. By analyzing the Nanopore signal, the PromethION software identifies the integrity of the nanopore array and provides the user with the number of nanopore channels available. The nanopores in the chip are divided into four groups. When sequencing for a long time (e.g. 64 hours), each group is sequenced in turn, and short time sequencing uses only part of the hole.
