Bio Coupler

BioCoupler for microclonal tissue culture.Is mixes, wets, agitates, coats, and moves the propagules about. It provides a high humidity, filtered air and gas exchange. It does all of this without troublesome plumbing, timers, valves, etc. And, electricity is not required. It has an integral vent hole covered by a long lasting microporous air filter with adjustable vanes that restrict the plant propagules in the top jar from falling into the liquid containing jar below. If needed, a fine mesh can be placed between the vanes but this is not normally needed.***The filament must be autoclavable at 121°C. I use PA-CF+ Synthetic filter paper sticker 20mm 0.2μm PTFE filter disc, strong adhesive patch for wide-necked lids, Mason jars for growing mushrooms+ Silicone seals for jars: 70mm
