The lab items produced by tedamed are now mainly centrifugal equipment, because these equipment are now sold very well in Africa and other regions. Of course, we will invest more funds to develop and produce other types of equipment in the future based on customer feedback. The main end customers of this type of lab items are school laboratories and hospital laboratories. The speed of 4000r/min is enough for daily experiments. Recently, molecular cooking is very popular. I think it should be very good to sell on Amazon. About lab items, if you have demand, we can wholesale to you at a very low price.
