Hi! What are some of your favorite high sheer blenders that don't let in much air and are commercially available at a reasonable price? I've been using stick blenders for a while, which aren't ideal given the amount of bubbling.
While on the topic, what are some of your favorite pieces of lab equipment for developing micro batch creams, lotions, toners, balms, etc?
This would be for a small experimental lab that produces up to 350oz at a time.
