In our laboratory, we are doing basic research on herbal plants and the present study involves polyherbal formulation (combination of 3 plants); we need to prepare aqueous extract for each 3 plants and planned to acquire maceration technique. I think at least 9 liters of solvents to be evaporated. When I approach other laboratories, I understand that this is a huge amount and very laborious with the machine, what do they have in their lab? Is there any commercial agency, who can help in this matter?
Thanking you in advance for your kind guidance.
Hello, This facility is availabe in "TAMIL NADU VETERINARY AND ANIMAL SCIENCES UNIVERSITY, Madhavaram Milk colony, Chennai". But i dont know whether they are commercially accessed or not?.
9 liters evaporation by lyophilisation in lab scale is difficult. Try to evaporate water under reduced pressure as much as possible and then final reduced concentrate can be lyophilised.
Hai Ma'am,
Do you mean the rotary evaporator as reduced pressure systems?. Please explain in brief about this.
Yes. Distillation under vacuum. As large quantity is being dealt, first it can be distilled under vacuum to its concentrate and then it can be lyophilised. Otherwise it consumes very long time for freeze drying.
