Improved analysis capabilities for algal research. PHYTO-PAM-II COMPACT version features detailed assessment of photosynthetic performance. Due to its high performance, samples from natural sea water up to culture grown algae strains can be analyzed with highest accuracy and consideration of their spectral peculiarities. For mixed algae population, PHYTO-PAM-II provides differentiated, group-divided information about relevant photosynthetic parameters.
Starting from the established DUAL-PAM-100 system, a “Kinetic LED Array Spectrophotometer” (KLAS) has been developed by Christoph Klughammer and Ulrich Schreiber. The device measures fast absorbance changes in the near-infrared range (NIR) concomitantly with green light-excited chlorophyll fluorescence. The ground-breaking system determines simultaneously the redox states of the PS I reaction center (P700), its electron donor plastocyanin, and its electron acceptor ferredoxin.
In cooperation with the Fraunhofer Institute for Integrated Circuits IIS, the Heinz Walz GmbH has developed a novel fluorometer which combines three-dimensional imaging of plants with spatially resolved analysis of photosynthesis. The device is designed to provide new insights in the complex relation between architecture and productivity of plants.
Sponsored by the LOEWE program for top level research of the German Federal State of Hessen, researchers at Geisenheim University have set up a FACE (Free Air Carbon Dioxide Enrichment) experiment. Goal of research is to understand how future elevated CO2 levels, which drive the global climate change, affect viticulture and horticulture. Continuous recording of photosynthesis by MONITORING-PAM fluorometers provides long-term, time-resolved information on photosynthesis under coming climate conditions.

In addition to the standard version employing blue light, the JUNIOR-PAM fluorometer is now available with a white LED. Besides different LEDs and filters, the two versions have the same specifications.
The MINI-PAM-II carries on the success of its predecessor “MINI-PAM” using most modern LED and computer technology. Operation and viewing of data occurs by a touchscreen which is easily readable in the field. Large storage capacity for data and commonly available spare batteries permit long-term research at remote places. A new fully digital leaf clip measures PAR, temperature and humidity.
The new CCD camera generation is coupled to the computer via a high speed GigE Vision camera connection providing secure data transfer for all IMAGING-PAM applications. The new 2/3” CCD camera IMAG-K6 inspires by its enhanced NIR sensitivity. To find more information about the IMAGING-PAM M-Series click following link.
German researchers have developed a breakthrough imaging method permitting rapid detection of herbicide resistant weeds. By measuring the maximum photosynthetic quantum yield of photosystem II (FV/FM), the method is much faster than established standard procedures.

The government of the Free State of Bavaria and the Bavarian Association of Industry and Commerce has conferred the Bavarian Exports Award to the Heinz Walz Company. Walz was selected because of its longstanding success in providing high-end analytical devices to international scientists in the area of photosynthesis research. On this occasion, a short movie was recorded introducing the Walz team who made this success possible.
Brand-new publication in collaboration with Walz! The authors Christof Klughammer, Katharina Siebke and Ulrich Schreiber link light-driven proton fluxes to carbon fixation. They measured simultaneously the electrochromic band shift in chloroplast membranes and CO2 uptake by combining the DUAL-PAM-100 with the GFS-3000 system. The full Photosynthesis Research paper is freely available.
An impressive video illustrating in situ investigations of cyanobacterial photosynthesis using a Walz DIVING-PAM fluorometer has been released. The video was recorded during a 2013 research campaign in Greenland which was targeted to photosynthesis of algae on surfaces of submarine mineral formations (ikaide columns). This research campaign was sponsored in part by Walz.
The upgrade 3000-C/U-LiFe for GFS-3000 Control Unit 3000-C is available now. Experience the advantages such as the graphical color display panel-PC, direct USB stick communication and the enormous flexibility of power options including trouble free shipment of LiFePO4 Batteries. For further information please contact us.
GFS-3000 can now be powered by LiFePO4 Batteries. LiFePO4 Batteries 3035-A exhibit 47% longer operation time under standard conditions in comparison to the Li-ion Battery 3025-A. LiFePO4 Batteries are environmental friendly, provide easy shipment as they do not exceed 100 Wh and are expandable from 15 to 20 Ah (2 x 7.5 - 10 Ah) exhibiting further 30% operation time elongation. An upgrade 3100-C/U-LiFe for GFS-3000 Control Units 3100-C sold with Li-ion Battery 3025-A is available.
A new paper employing the MULTI-COLOR-PAM fluorometer to study destruction of photosystem II by light of different wavelengths has recently been published: Schreiber U, Klughammer C (2013) Photosynthesis Research 114: 165-177. Still available for free download is a related publication by Schreiber et al. (2012).
By employing a Walz DUAL-PAM-100 system, a French-German team has introduced a straightforward method to determine the level of PS I fluorescence. The method takes into account the various spectral properties of different PAM fluorometers and, thus, yields customized and authentic results: Pfündel EE, Klughammer C, Meister A, Cerovic ZG (2013) Photosynthesis Research 114: 189-206
WATER-PAM is operable by WinControl-3 software, the latest version of the WinControl software family. A WinControl-3 manual for WATER-PAM is now available. Also PAM-CONTROL and WATER-PAM manuals are revised and can be downloaded.
The new LED-Panel RGBW-L084 provides illumination for the Gas-Exchange Chamber 3010-GWK1. The densely packed array of high-power color-LEDs distribute uniform light with individual adjustable colors Red, Green, Blue and White.
Both the Cold Traps KF-18/2B and KF-24/6B as well as the Measuring Gas Cooler MGK-1B are the most classical and reliable instruments, exactly controlling the humidity in gas streams. Now their Temperature Controllers TR-KF-18 and TR-KF-24 have been redesigned. They feature a digital regulation and are operated via an integrated panel-PC with comfortable graphic display and touch panel.
The new version of the US-T unit uses an external Pt100 resistance thermometer to accurately measure the temperature in suspensions. A powerful Peltier device permits adjusting temperatures within a spread of nearly 30 K. The US-T unit can be utilized in combination with the devices DUAL-PAM-100, MULTI-COLOR-PAM, and PHYTO-PAM.
