Description A female connector is a connector used for electrical, physical or data transfer. A female connector has one or more holes into which a male connector can attach its exposed plug-type conductor firmly for a reliable connection. Female connectors are recognized by their physical characteristics. When the male connector has been removed, a female connector’s conductor is not exposed like that of a male connector, and can not come into accidental contact with objects. Some of the most commonly found examples of female connectors are standard electrical outlets as well as phone and Ethernet jacks. What is the difference between male and female connectors? A male connector is commonly referred to as a plug and has a solid pin for a center conductor. A female connector is commonly referred to as a jack and has a center conductor with a hole in it to accept the male pin.

Description Fenitrothion Rapid Test Kit         Principle Fenitrothion rapid test kit is based on lateral flow immunochromatographic assay. The test device has a testing window. The testing window has an invisible T (test) zone and C (control) zone. When sample is applied into the sample hole on the device, the liquid will laterally flow on the surface of the test strip. If there is little Fenitrothion in the sample, a visible T band will appear; T band is invisible if it has more Fenitrothion in the sample. The C band should always appear after a sample is applied, indicating a valid result. By this means, the device can accurately indicate the presence of Fenitrothion in the fruit, vegetables, grains,milk sample.   Technical Specification                                                 Detect limit：  200ppb            Reaction temperature: 25℃ Detect time:   30min.   Materials provided                                                  Rapid Test Card 20PCS PBS solution     50mL   Materials required not provided                                         Deionized water, Ethyl acetate Centrifuge tube:  5mL, 10mL Micropipettors:  20~200 µL, 100~ 1000 µL Vortex, centrifuge, balance (0.01 g), homogenizer, shaker Sample Preparation                                              Take 5±05g of the homogenized sample, add 5mL deionized water, then add 5mL ethyl acetate , shake for 5min properly. Centrifuge at above 4000 r/min at room temperature (20-25 ℃) for 10 min. Transfer 3mL supernatant, evaporate to dryness by nitrogen at 50~60 ℃. Dissolve the dry residue in 200uL PBS solution , mix for 30s. Take 80µL for analysis. Sample Determination                                                                                      Take out the cassette from the pack and place it horizontally. Return to room temperature (20-25℃), determine the cassette immediately. Add 2 drops(Approx 80µL) sample extraction, react for 5-10 min and read result. Result Judgement   Positive: The presence of “C” band, no matter “T” It means that Fenitrothion in the sample extraction is higher than 200ppb. Negative: Both clear“C” band and “T” band appears. It means that Fenitrothion in the sample extractionis lower than 200ppb . Invalid: No colored band appears in C zone, no matter whether T band appears.   Note                                                              For best results, please strictly adhere to these instructions. All reagents must be at room temperature before running the assay. Do not remove test cassette from its pouch until immediately before use. Do not reuse the test kit. Do not use the test beyond its expiration date marked on the foil pouch. The components in this kit have been quality control tested as standard batch unit. Do not mix components from different lot numbers.     Storage and expiry date                                              Store at 4-30 °C for 12 months in the dark. Do not freeze. Expiry date is labelled on the package.

Description Fermentation System – CO2 Absorption System for 4 absorption bottles PRODUCT DESCRIPTION Maximum precise measurement results with individually calibrated RITTER MilliGascounters RITTER Engineering has been successfully working in the field of plastic engineering for 60 years. Among other products RITTER manufactures Gas Flow Meters made of various superior plastics and high grade stainless steel. RITTER meters are used world-wide in research & development laboratories as well as in industry. The MilliGascounter was developed for the volumetric measurement of the smallest amounts of gas with ultra-low flow rates. These small devices are suitable for measurement of inert, and slightly corrosive biogas, as well as most aggressive gases. Each MilliGascounter is individually calibrated and supplied with an individual calibration certificate. By PTB calibration of RITTER master meters the traceability to the national primary standard for each MilliGascounter is given. As a result, maximum measurement accuracy is guaranteed which provides the necessary basis for any research. In the field of the biogas research the RITTER MilliGascounter became a cent­ral component of a system allowing investigation of fermentation processes with up to 16 fermentation bottles in a heating oven at the same time. This RITTER Biogas Batch Fermentation System enables automatic measurement with data acquisition in real time. The primary advantage of the RITTER Biogas Batch Fermentation System is that the entire fermentation bottle is uniformly tempered inside the heating oven. In contrast to tempering the fermentation bottles in a water bath there will be no uncontrolled cooling of the upper half of the bottles by air and air currents. All temperature deviations can be minimized by e.g. an optional inner glass door of the heating oven for visual inspections. Preconfigured packages The RITTER Biogas Batch Fermentation System is available as a package for 8 or 16 fermentation bottles. For; 8x 1x Heating oven FD56 with lead-through in heating oven top panel for gas tubing 1x Tube distribution frame for MilliGascounters on top panel of heating oven 8x MilliGascounters MGC-1 PMMA 8x Tubing connection from fermentation bottle to MilliGascounter 8x Fermentation Glass Bottle, 1 ltr GL 80 8x Stirring device for fermentation bottles 1x Control unit for 8 stirring devices incl. power supply unit 1x Licence for »RIGAMO«-Software 8-Channel 1x Digital Interface Module (»DIM«) 8-Channel 16x 1x Heating oven FD115 with lead-through in heating oven top panel for gas tubing 1x Tube distribution frame for MilliGascounters on top panel of heating oven 16x MilliGascounters MGC-1 PMMA 16x Tubing connection from fermentation bottle to MilliGascounter 16x Fermentation Glass Bottle, 1 ltr GL 80 16x Stirring device for fermentation bottles 1x Control unit for 16 stirring devices incl. power supply unit 1x Licence for »RIGAMO«-Software 16-Channel 1x Digital Interface Module (»DIM«) 16-Channel
