Roller Drums for tissue culture; a question of rotation speed
Al: You might try a washing machine motor. Find one with a 100%
duty cycle, and you're set. Something you might consider instead of a shaker table is a rocker table. Under one end of the table is a motor that drives an eccentric wheel; the wheel raises the table up, and then it gently goes back down. There is nothing "magic" about orbital shakers or wheels when you're talking about the rpms that work for what you're doing. All you're trying to do is dilute the waste products, and bring in new nutrient solution. Now, bacterial cultures and callus of other species sometimes like it at much higher speeds, but not for phal callus. For lower rates, you can get a timing motor cheap on eBay or from American Science and Surplus or something like that. Do not reply to the e-mail address in the header. It all goes to the FTC. -AJHicks Chandler, AZ |
