Central Sterilization Services (CSS)

The Central Sterilization Services (CSS) located in the Medical Sciences Building (MSB) room 4179 and allows researchers to consolidate their glass-washing and sterilization needs. Trained, experienced staff handle all the processes such that researchers and trainees can focus their time on experiments instead of time-intensive preparatory work. The facility is equipped with three research-grade glass washing machines supplied by a high-end water filtration system to ensure glassware and plasticware is free of residual mineral contaminants. For sterilization purposes, CSS operates 6 maintained and validated autoclaves.

Unit Pricing and Billing

As with other local sterilization facilities, CSS operates as a cost-recovery facility and the direct operational costs are charged back to users on a per-unit usage basis. CSS has aligned our pricing to that of UHN MedRIST (sterilization facility servicing MaRS based researchers).

To accurately track usage, each individual piece is counted and assigned to the respective lab.

Direct costs are billed to each Department on a monthly basis, along with a comprehensive invoice breaking down each lab’s respective usage so that departmental Business Officers can accurately reassign costs to PI’s.
