HDDV series features
The V series adopts a D-shaped sleeve structure for magneticdriven polishing shells, mainly suitable for use in low flow and highvacuum scenarios. lt transports and measures liquids under cer-tain vacuum conditions or initial pressure. The structure adopts apolished shell, making it easy to clean the shell.
