Laboratory Waste Liquid Recycler: Use the suction head to absorb the waste liquid in the petri dish to better deal with the residual liquid in the petri dish after the experiment. Various adapters can fit tubes, microplates and disc plates for various tasks. 9-speed Adjustment: 9-speed setting can better control the suction speed and improve the success rate. To achieve a suction speed of 1.6L/min to 6L/min.Liquid collection bottle and nozzle can withstand high temperature of 121℃. Wide Application: 8-channel suction head, used when collecting waste liquid from 96-well plates; 200ul suction head, used for adherent cell culture, used when regularly changing nutrient solution. Thoughtful Design: Non-slip foot pads, firm adsorption, can be used on a smooth desktop; storage bracket, convenient storage of pipette tips, clean and tidy; high-quality filter membrane can prevent waste liquid from being sucked back and damaging the instrument. Easy to Use and Clean: Sensitive liquid level sensor prevents liquid from overflowing during operation. The lid, tube and handle are easy to remove and clean.
