It completely avoids the disadvantages of the traditional manual operation of easy-to-use bacteria, the easy destruction of the seed surface, the inability to manipulate small seeds such as oilseed rape, and low efficiency. Make the work efficiency and work quality greatly improved. Technical indicators: Equipped with curved and straight tips for easy work breakdown With suction cups of three sizes: large, medium and small, easy to suck and discharge seeds of different sizes Maximum power: 26W Voltage: 220V Maximum suction: 100g installation method: 1. Connect the suction tube to the main unit and connect the elbow or straight nozzle to the pen port. Then select the appropriate suction cup according to the size of the experimental seed. 2.

Instructions: When using, you can use the position of holding the pen to turn on the power, and gently hold the side hole of the pen with your thumb or index finger. At this time, the instrument is in the suction state, and you can suck the seed in the seed tray.
