    Posted on January 26th, 2007 tommy No comments

          Several days ago, I offered the laminar flow price to my client from India . But yesterday  he told me the temperature is from 50 degree to 121 degree . I asked my consulter who has many experiences in pharmaceutics field , but he never heard this type laminar flow.

        Today I will send the catalogue to my client in Austria by UPS. The client needs G3-F9 bag filter.
