[ynakao at kean.ucs.mun.ca]

Dear netters in Japan 
      I am looking for the company selling the metal grid for RAFT culture(
10cm diameter) in Japan. If it is impossible to buy it in Japan,please tell 
me the cheapest and reliable company you recommend. To tell the truth, my 
senior is the realy person who want. But our lab.(in Japan) doesn't exist
 the terminal of internet! So, I ask you instead of him.   
                Thanks in advance
