LSA-2050/DB

Accessory

Darkening Bags

  • Overview
  • Specifications
light-tight dark acclimation bag applied to a plant leaf for Fv/Fm maximum quantum yield measurement with PAM fluorometer
dark acclimation bags in three sizes with central measurement clip for Fv/Fm quantum yield measurement

The accessory is designed for darkening of leaves in the field. Dark-acclimation is prerequisite to measure the maximum photosystem II quantum yield, FV/FM. The bags consist of light-tight material. Chlorophyll concentration can be determined through a central hole. The bags are available in three sizes. For details see Specifications.

General design
Set of three small, three medium and three large light-tight bags for dark acclimation of leaves of different sizes made of aluminum foil, colored on the outside. Each bag has a 2 cm diameter central hole for non-invasive determination of chlorophyll concentration with the LSA-2050. During dark acclimation, both sides of the hole are covered by metallized PET plastic flaps. The flaps magnetically attract each other which ensures that both lie tightly on the surface of the bag. The flaps are flexibly attached to the darkening bag at one end. The other, loose end is folded slightly outwards so that the sample clip of the LSA-2050 can be guided to the hole by folding open the flaps
