ABSTRACT
Prospective isolator purchasers should bear in mind that the preparation of this kind of documentation can be a lengthy process and commits the isolator supplier to considerable effort with no guarantee of a successful bid. Thus, a period of one week from the issue of a tender to the deadline for bid submission is not sufficient; at least one month should be allowed. During this time, the purchaser should expect to answer a number of queries as the supplier develops the proposal; if there are no questions, the supplier probably does not understand the tender.
