Chemistry diaphragm pumps and pumping systems
Typical applications for chemistry diaphragm pumps include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry diaphragm pumps from VACUUBRAND feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. Our two-, three- and four-stage pumps also have a gas ballast valve that provides continuous purge with minimal impact on ultimate vacuum when working with condensable vapors. Pumping chambers are hermetically separated from the drive system ensuring long lifetimes of mechanical parts. Most importantly,diaphragm pumps are oil-free, for vastly reduced service demands compared with oil-sealed pumps. They eliminate the cost of water and its contamination well-known from water-jet aspirators, and the waste-oil disposal of rotary vane pumps.

MicroJet Autoclave

  The modern Microjet Personal Microwave Autoclave has a space saving, benchtop design. One of the main USP's of the Microjet is its fast sterilisation process; owing to the application of "Direct Energy Transfer technology". The “Direct Energy Transfer technology” is a revolutionary process which utilises microwave automation, instead of the traditional 'pressure cooker' approach.   Microjet Personal Microwave Autoclave Benefits:   It only takes 7 minutes* to sterilise (5 times faster than traditional sterilisation) Operation of the autoclave is intuitive, it does not require additional training Touchscreen Technology: The modern design of the autoclave means all functions are touchscreen operated. To improve lab efficiency, the Microjet includes modern functionalities, including real-time monitoring of the sterilisation progress Liquid media such as microbiological media, buffer solutions, carbohydrate solutions or water can be sterilised in standard laboratory vessels of 100 to 500 ml capacity  Temperature resistant up to 135°C (glass or plastic – PMP, PP, PTFE, FEP) Each operation is automatically stored on a Micro SD card As the data is stored in a format compatible with GLP, it can be copied to any PC and read using the inclusive ENBIO Data Viewer software. Competitively Priced 2 year warranty * based on using a 150ml volume Duran bottle   Microjet Personal Microwave Autoclave Specifications:   Sterilisation temperature: 135°C Exposure time to process temperature: 25 s Heating time: 1-5 min Cooling time: 4-12 min Total process duration: 7-15 min Power supply: 230 V/50-60Hz Power output: 0,95 kW Maximum power consumption: 8 A Operating pressure: 3,4 bar Weight: 15 kg Dimensions: 280 x 280 x 427 mm Process chamber capacity: 2 dm3 EM wave frequency: 2450 MHz Protection: IP 20 Data Logging: micro SD card
