The free air displacement of the pump should be matched to the size of the desiccator to ensure a satisfactory pump down time. • Use WOB-L piston pumps for standard duty aqueous applications, with a high pumping speed for quick eva- cuation of your desiccator. These pumps come with a vacuum regulator and dial vacuum gauge as standard for controlled evacuation and vacuum level monitoring. • Use chemical duty MPC diaphragm pumps when sol- vents are being used. These rugged diaphragm pumps use PTFE and other chemical duty materials for protec- tion against damage from solvents. Use the optional DRB regulator with dial gauge if vacuum regulation is required.

Besides the intelligent ecoflex control system, the connected chemical duty diaphragm pump is very quiet in operation and can be reached easily for cleaning or maintenance purposes. With an ultimate vacuum of 2 mbar and a peak flow of 36 l/min the LVS 210 T ef has been optimised for applications in chemical, biological and pharmaceu- tical laboratories and is suitable for use in multi user network (Netvac) systems. The Ecoflex control con- tinuously adjusts the pumping speed to match the vapour load of the process. An inlet trap protects the pump from ingesting liquids and particles and an exhaust vapour condenser for optimal solvent re- covery. LVS 610 T ef The LVS 610 T ef is an excellent oil-free, chemical LVS 610 T ef | 115254 resistant solution for multi user network (Netvac) systems. With an ultimate vacuum of 2 mbar and a peak flow of 81 l/min the LVS 610 T ef has been op- timised for applications in chemical, biological and pharmaceutical laboratories and can pump corrosi- ve and aggressive gases and vapours. The high flow rate and deep vacuum allow it to supply vacuum to approximately 10 individual ports. It is designed for continuous duty and comes with the ecoflex control system which continuously ad- justs the pumping speed to match the vapour load of the process and allows the pump to operated un- attended.

They comprise an oil-free chemical duty diaphragm pump (MPC) with optional control packages, liquid containment and exhaust vapour condenser. All wetted parts are made from high quality chemically resistant materi- als with clear plastic coated glassware to allow sol- vent and acid vapours to be pumped. www.welchvacuum.com I 27

4 LVS Model options The LVS systems are available with a range of vacuum control options; unregulated, manually regulated and three different electronic control packages are available. Unregulated • When ultimate vacuum is required at all times. LVS 300 Z Manually regulated • A fine control valve is used to regulate the vacuum by acting as a bleed valve. Options available with one or two manual regulators. Standard digital control (cv) LVS 301 Z LVS 310 Z • The standard electronic control package uses a chemically resistant solenoid LVS 310 Z en valve to control the process vacuum while the pump runs continually. LVS 310 Z ef • The user defined vacuum and hysteresis levels are used to open and close the control valve thus maintaining vacuum at the process between the high and low control points. This is known as two point control. Economic digital control (en) • Economic control uses the same two point control system, but as cv replaces the control valve with a relay which turns the pump on and off to maintain the process vacuum between the user defined vacuum and hysteresis levels. This method greatly reduces power consumption and extends the lifetime of the pump. • Economic control is particularly useful for multi-user vacuum networks where the pump is located away from the user. Ecoflex digital control (ef) • Ecoflex control varies the speed of the pump constantly to maintain the user defined vacuum level regardless of changes in the process requirements. • The Ecoflex method exhibits genuine single point (hysteresis-free) control and therefore a stable vacuum level. • Single point control results in up to 40% increase in evaporation rates with mi- nimal bumping or foaming of precious samples. This is particularly important in ultimate rotary evaporation. 28 I www.welchvacuum.com
