Between the host and the vacuum pump from the vacuum tube connected to the clamp of the junction to adopt international standards. The clamp contains a rubber seal ring before connecting to smear the right amount of vacuum grease on the rubber ring, and then clamp clamping.
Freeze-drying machine, the right side panel has an outlet of the vacuum pump, vacuum pump power cord is connected.
Check the vacuum pump, confirmation has been filling the vacuum pump oil, not oil-free operation. The oil level shall not be less than the center line of the oil immersion lens.
Host cold trap above the "O" type rubber seal ring should be kept clean, first use, apply a thin layer of vacuum grease, organic glass is placed on the rubber ring and gently rotating a few, sealed
