Diaphragm pumps

The Rotary Vane Vacuum Pump RC 6 has been designed to minimise the adverse effects of condensable and corrosive vapours. Its main components are a two-stage rotary-vane pump and a two-stage chemistry diaphragm for optimised corrosion resistance. The diaphragm pump continuously evacuates the oil reservoir of the rotary-vane pump in order to keep the partial pressures of solvent vapours, oxygen and corrosive gases at a low level and/or below their condensation point. The RC 6 is a low-maintenance pump for freeze-drying and other applications requiring an ultimate vacuum in the 10^-3 mbar range.

Scope of supply: Pump, overload circuit breaker and mains cable (2 m), centering and clamping ring for inlet, particulate filter, operating instructions, oil (bottle of 500 ml)

• Gentle drying of heat sensitive materials
• Significantly reduced drying times when compared to convectional oven without vacuum
• Drying of intricately designed parts
• Elimination of oxidation associated with heat treatment
• Targeted recovery of degassed product
• Capacity refers to the trap in ml

Measures and displays vacuum pressure both graphically and digitally from 1100 to 1 mbar. Controlling the pressure can be done in real-time. The durable, chemically resistant sensor built into the VCpro 601 vacuum controller is a ceramic thick film hybrid. The sensor reading is gas independent and gives an absolute pressure.

• Precise vacuum control with timed ramp capability
• Fully programmable modes to allow run repeatability
• Intuitive ICON-navigation of control screens
• Connectivity through LAN and RS232
• Built-in function for self-cleaning of diaphragm pump
• Security levels for administrators and users
• Log files on all pump activities for easy traceability
• High-Res display with dark and light screen modes
• Digital and analogue vacuum pressure display
• Automatic destillation control
• Can be used with diaphragm or piston pumps from any manufacturer

The compact pumps feature a control knob for manual adjustments of the flow rate, making them well suited to a wide variety of applications, e.g. rotary evaporation, distillation, gel drying, degassing as well as the use with vacuum ovens and vacuum concentrators. Due to the manual rotational speed control, the pumps are quiet, very energy efficient, and can be optimally adjusted in accordance with the application.

• Easy-to-clean surface
• Adjustable in flow rate due to manual rotational speed control
• Combination of PTFE pump head and PTFE-coated diaphragm makes the pump ideal for extremely aggressive/corrosive gases and vapors
• High level of compatibility with vapor and condensation
• Integrated gas ballast valve
• 3-color status display: In operation / Stand-by / Error
• ATEX-compliant in accordance with II 2/-G IIB+H2 T3 internal atmpsphere only
• 100% oil-free transfer to ensure uncontaminated transfer, evacuation and compression
• Optional: Easily expandable with separators and/or condensers

The Pump combines a high flow rate with a very compact design. Suitable for filtration, SPE, and liquid aspiration using a vacuum. Due to the manual rotational speed control, the pump is quiet, very energy efficient, and can be optimally adjusted in accordance with the application.

• Easy-to-clean surface
• Very small footprint
• Adjustable in flowrate due to manual rotational speed control
• PTFE-coated diaphragm for use with aggressive/corrosive gases and vapors

For the maintenance of KNF pumps. Contains all necessary membranes, seals, etc.

Comfortable, precise and performant peristaltic pumps for continuous operation in various speed ranges. With control of speed and flow rate. Housings are available in white powder-coating (IP54 protection) and stainless steel ("i" models, IP65 protection). With integrated RFID technology for detection of pump head and hose as well as automatic blockage detection and hose burst control. A control panel for the most important functions is integrated directly at the pump housing, the external control panel is equipped with a touch screen. The connection technology of the pump heads guarantees rapid handling.

• External control panel, detachable
• Pump drives with two different motors (50 or 100 watts) are available depending on the application, flow rate and medium
• Exchangeable pump heads in single-channel or multi-channel design (not included in scope of delivery)
• Reversible conveying direction
• Quick exchange of pump heads without the use of tools
• TFT touch screen with user-friendly menu
• Calibratable
• Integrated method memory
• Flow rate, calibration function, method memory programmable on the operating module
• USB and RS232 interface for PC connection
• Pump heads of other manufacturers can be used without difficulty via adapter

For use with all rotarus^® peristaltic pumps.

The DITABIS Aspiration Systems are made for the controlled aspiration of liquids from typical lab containers like cuvettes, tubes, microplates, petri dishes or roller bottles. They are also suited for the disposal of liquid biological or chemical waste and filtration of liquids by means of filter systems.

• Membrane vacuum pump
• 2L or 4L bottle incl. fast lock clutches, filter, ventilation insert and 3M silicone hose

• Membrane vacuum pump turns on and off automatically
• AA 02/04 with 1 handle
• AA 24 with 4L bottle, 2 handles and Y connector
• Enlarge the automatic suction system by adding up to 4 working places and reduce your expenses for each user.

• Membrane pump with manual switch-off
• 2L or 4L bottle

• Small membrane vacuum pump

The electric neoprene diaphragm pumps are suitable for routine use in a microbiological laboratory. Controlled vacuum ensures that stressed microorganisms (e.g., bacteria) are gently concentrated on the membrane filter surface. This leads to lower mortality, which in turn leads to higher recovery rates and shorter incubation times.

• Low noise level
• Oil and maintenance free
• Single filtration with single bar or single filter holder (mini.vac)
• Parallel filtration with multiple strips (maxi.vac)
