6) 04821008 6 Quick Release Nut 04821131 semi-demountable cells and Windows FOR HIgH-VISCOSITy lIquIdS OR Mull SAMplES By using rectangular windows instead of circular windows, the demountable cell becomes a semi-demountable cell.
The semi-demountable cell can be used either as a demountable cell or as a sealed cell for high-viscosity liquids or mull samples.
To order a semi-demountable cell, order the Universal Demountable Cell (L1270986) and your choice of semi-demountable windows and spacers.
