>in response to Vibration isolation tables:
We tried a granite base with a 8inch thick polyfoam base. It was satisfactory only in some situations. Since our laboratory is located on the 6th floor and directlt below airconditioning equipment etc. a vibration free table was imperative.We are very happy with a TMC product.
