Vacuum pumps

Vacuum pumps are used to remove gas (often air) from a volume to create a partial vacuum. There are various types of vacuum pumps which are suitable to operate under different conditions and have different pumping capacities. In experiments that involve hazardous substances, it is important to consider chemical resistance and durability.

Wet gas vacuum pump Laboport SD N 860.3 FT.40.18 KNF-cover
Wet gas vacuum pump Laboport SD N 860.3 FT.40.18 KNF

Laboport SD N 860.3 FT.40.18 is a two-stage pump with an integrated “self-drying” system for automat (more)ic condensate drain. The “SD” series is widely used in laboratories, especially when the vapors are humid and a clean and ecological vacuum is required. Typical applications are: vacuum ovens (for drying chemicals, drying biological samples, heat treatments), autoclaves for sterilizing instruments, containers, filters and textiles. Thanks to the use of anti-corrosion materials, it is possible to vacuum even corrosive products. The heart of the pump is the diaphragm with differentiated structure in PTFE, optimized to guarantee high performance with reduced dimensions and at the same time, long life even in heavy applications. When the humid gases are sucked in, it can happen that condensation forms in the pump head: consequently the performance decreases, considerably increasing the emptying time. To eliminate condensation, the 'drying system' then opens a solenoid valve that allows ambient air to enter the heads. Once the condensation has been eliminated, the solenoid valve closes and the pump sucks from the stove in full capacity. Over time, condensation could form again and then the cycle is repeated. The time interval between one cycle and the next can be adjusted as desired, as well as the duration of the air injection. Technical features Flow rate (max.) 60 l / min Final vacuum (max.) 4 mbar (abs.) Pressure (max.) 1 bar (rel.)

KNF SC 920 Vacuum Pump System

Deliver precise vacuum and offer widely diverse control functions for a huge range of applications i (more)n the laboratory. The intuitive user guidance on the hand terminal ensures ease of operation; the process parameters can be entered over a touchscreen and a rotation knob. Ajustment capabilities: Units of measurement The operating language The operating mode Parameters, such as the setpoint pressure or suction capacity of the system direct over rotation knob. Depending on the selected operating mode, the graphic display of the hand terminal then indicates the respective process variables. The user can intervene in the ongoing process at any time with the hand terminal and its integrated touchscreen and rotating knob. The hand terminal can be located via vacuum pump system (paging); the hand terminal will answer with a signal tone. Four operating modes: Evacuate – The vacuum pump system evacuates a vacuum chamber with adjustable pump capacity. Pressure control – The vacuum pump system controls the system pressure to the set value (constant pressure). Automatic – The vacuum pump system automatically finds the vapour pressure of the sample and adjusts the process pressure accordingly. Individual pressure function – The vacuum pump system controls the process according to a user-defined pressure curve. The setpoint pressure and the opening and closing of the coolant valve (accessory) on the high-performance condenser can be easily entered for a range of set times. A repeat function allows successive repetitions of the programmed pressure curve.At any time during an active process, you can switch to manual process control. Functions for Evacuate and Pressure control will be available simultaneously.
