Although I appreciate that vials and inserts cost money, the cost in terms of time, solvents, cleaning fluids etc. in cleaning these items for re-use, outweighs the cost of purchasing new vials and inserts.
thanks Ade, in fact we tried to use always new disposables, we´re running a validation protocol and our suplier for vials have a problem with the order requisition and we will nedd to re-use it while we get the new ones .
