32 New Gel Documentation System


Syngene is pleased to introduce its new InGenius3, feature-packed gel imaging system. Designed with a compact darkroom, as well as blue, white and UV lighting options, InGenius3 offers maximum gel imaging versatility at an affordable price.


The InGenius3 features a high-resolution three million pixel CCD camera that can be connected to the laboratory’s choice of PC. The system is controlled by Syngene’s intuitive GeneSys imaging software, which guides scientists to the correct combination of filters and lighting, making it easy to set up InGenius3 to produce high quality gel images every time.


The InGenius3 system comes with overhead Epi white light and offers multiple illumination options. These include the new Ultra-Slim LED Blue Light Transilluminator, which is ideal for laboratories where safety and UV sample damage are a major concern. The transilluminator slides out of the darkroom to aid viewing and cutting gel bands, and there is a White Light Converter screen option for scientists wanting to view protein gels.


The InGenius3 system has manual control functionality, enabling users to easily change lighting conditions, camera aperture, zoom and focus, and quickly switch between filters using a filter drawer. The system also includes GeneTools image analysis software to enable scientists to rapidly analyse their gel images.


Laura Sullivan, Syngene’s Divisional Manager, stated: “To continue Syngene’s theme of easy imaging, the new InGenius3 is the ideal economical choice when budget and size are the most important considerations, but high resolution imaging is also a priority. The system is specifically designed for viewing gels in laboratories where bench space is limited, yet doesn’t compromise on performance, which means capturing great gel images every time has never been easier.”

Shimadzu has released the new TOC-4200 online analyser. It represents a new generation that offers the ability to use new modes of communication. The TOC-4200 covers features such as web-based monitoring and Modbus protocol for two-way digital communication, and it offers new functionality that provides a wider range of potential applications.


Novel Fibre Optic Chemical Sensors Provide Real-Time Non-Intrusive Monitoring


Advances in high-performance sensor materials and optoelectronics have enabled novel optical sensors for use in applications in life sciences, pharmaceuticals, biotechnology, food and beverage processing and more. Compared with traditional electrochemical sensing techniques such as galvanic sensors, Ocean Optics optical sensors can be made in small and customisable form factors, allow non-intrusive measurements and do not consume the sample.


Ocean Optics’ optical O2 and pH sensors are designed for accurate, real-time, in situ measurements in various media. The proprietary sensor coating materials do not consume the


sample and can be applied to substrates such as probes, self-adhesive acrylic patches and microtiter wells. Coating options are available for general lab use, food processing lines and hydrocarbon-rich environments. Depending on the application, oxygen presence or pH can be visually determined by colour change with a handheld LED, or a fluorometer can be used to make exact measurements.


The principle of operation is to trap an oxygen-sensitive fluorophore or pH indicator dye in a sol-gel host matrix that can be applied to the tip of a fibre, an adhesive membrane such as a patch or a flat substrate such as a cuvette. The indicator materials change optical properties in response to specific analytes in their immediate environment and electronics then measure the response. For oxygen, the NeoFox Phase Fluorometer measures the partial pressure of dissolved or gaseous oxygen; for pH, a miniature fibre optic spectrometer measures the colorimetric (absorbance) response of the pH dye.


Ocean Optics optical oxygen and pH patches overcome the limitations of electrochemical-based oxygen and pH sensing. Such patches can be integrated easily within a small-scale biosystem such as a bioflask used for fermentation and provide continuous, non-intrusive monitoring of key system parameters. The ability to monitor dissolved oxygen and pH in real time without perturbing a sealed environment can lead to an improved understanding of the processes in the bioreactor and help to facilitate the development of new biological products and fermentation processes

Modbus two-way digital communication capability enables controlling two-way communication for multiple devices over a single integrated signal line, which also simplifies electrical wiring work. This allows connecting to two-way communication networks. The optional web-based monitoring function allows monitoring the measurement data or status of instruments from any network-connected computer in the world.


The eco mode reduces waste by only using carrier gas and operating the sampling pump when it is needed for measurements. Maintenance costs are cut by Shimadzu's unique multifunctional sample processing injection system reducing part count by integrating functions into an 8-port valve and syringe pump. Offline measurements can be performed by interrupting online measurements without stopping them. When offline measurements are finished, online measurements resume automatically. This enables more efficient offline measurements.


The TOC-4200 helps to prevent measurement interruption due to the running out of reagents or other consumables by providing notification through the communication methods such as screen and contact output when the replacement period approaches. Measurement data and calibration history can be stored in the instrument up to one year. Stored data can be removed via USB memory and valuable measurement data can be backed up inside the instrument.

An optional high-sensitivity kit enables measurements of samples with TOC concentrations below 1 mg C/L. The high-salt sample combustion tube kit significantly increases the period between maintenance, by about 10 times, when measuring sea water or other samples containing high salt levels. Adding the TN measurement option permits total nitrogen (TN) measurement with catalytic combustion and chemiluminescence detection.
