Accessories

Suspension Cuvette KS-2500 and Stirrer MKS-2500

Cuvette: Round stainless steel cuvette (7.5 mm wide, 9.0 mm deep) with top window adapter for connecting the fiberoptics; embedded in PVC body with injection port for
Hamilton syringes and hose nozzles for connecting an external flow-through water bath (not included). Including three 6.0 x 1.5 mm magnetic stir bars

Magnetic stirrer: To drive the magnetic stir bar in the Suspension Cuvette KS-2500; with PVC ring for centering the cuvette and miniature stand to fix the fiberoptics on top of the cuvette

Arabidopsis Leaf Holder DUAL-BA

Design: Tube-shaped fiber tip holder composed of polyoxymethylene (POM; 4.5 cm x 2.5 cm, L x D max,) with laterally positioned, recessed permanent samarium-cobalt magnet. Spring steel band (0.3 mm thick, 1.5 cm wide) consisting of two sides (2 cm and 5 cm, respectively) which form a right angle. The leaf is positioned between the 2 cm side of the steel band and the fiber optics tip. The steel band is attached to the fiber tip holder by placing the 5 cm side of the steel band on the fiber tip holder’s magnet. Including a guide loop (length 3 cm, diameter 2.5 cm) for fiber optics with an 11 cm steel rod (0.8 cm diameter) for mounting to a stand
