To avoid contamination of workspaces by splashing and the like of a waste fluid. A fluid delivery system for delivering a fluid from one container to another container includes: a delivery channel connecting between the one container to the other container; and a delivery pump which feeds the fluid into the delivery channel by compressively deforming inner diameter in the middle of the delivery channel, wherein the delivery channel is a partially elastic configuration that can be compressively deformed by the delivery pump, and also is a closed-system configuration with which the fluid flowing inside thereof is isolated from outside. As described, the delivery pump and the delivery tube or the waste-fluid container are not directly connected but are simply in contact. Therefore, it is possible to prevent splashing and the like of the waste fluid onto a work space when handling the waste fluid.

Fluid delivery system

This invention relates to crystals of compounds of formula (I), wherein TBS represents t-butyldimethylsilyl, and Ph represents phenyl, or its salt or solvate. Compounds of formula (I) are synthesis intermediates of 2-substituted-1&#x3b2;-methyl carbapenem compounds useful as antimicrobial agents. The crystals of the present invention have excellent handleability and can realize the production of carbapenem compounds having excellent antimicrobial activity in a simpler manner with improved yield and purity.
