multi- parallel bioreactor system
An ACAN is a public notice indicating to the supplier community that a department or agency intends to award a contract for goods, services or construction to a pre-identified supplier, thereby allowing other suppliers to signal their interest in bidding, by submitting a statement of capabilities. If no supplier submits a statement of capabilities that meets the requirements set out in the ACAN, on or before the closing date stated in the ACAN, the contracting officer may then proceed with the award to the pre-identified supplier.
The National Research Council (NRC) of Canada has a requirement for the supply of an 8-units multi-parallel bioreactor system for cell culture. This system will be used for high-throughput upstream process development of cell culture-based bioprocess for the manufacturing, of monoclonal antibodies, recombinant protein, viral vector, vaccines, viruses and virus-like-particle and cell and gene therapy. The system needs to operate both glass bioreactor vessels, and fully bioreactor single-use vessels. The system to be purchased comprise of bioreactor controllers with all required all cables, probes and accessories to meet the criteria listed in Section 3, 8 glass vessels of 0.35-1L working volume, and one operator interface or Human-Machine Interface (HMI) interfaced with all eight bioreactors for the use of the operator to set up the bioreactor parameters setpoint, control strategy and trending. It will be used in the Human Health Therapeutics Research Center Bioprocess facility by the Cell Culture Scale-Up Team at its Royalmount facility in Montreal.
3. Criteria for assessment of the Statement of Capabilities (Minimum Mandatory Requirements):
Any interested supplier must demonstrate by way of a statement of capabilities that its system meets the following mandatory technical requirements: Space constraints: The system, including the bioreactor controller, the vessels themselves, the control screen must fit into a 72” x 32” benchspace (width x depth) inside a BSL-II biosafety cabinet, with a maximum height of 81”.

The exhaust filter of the bioreactor must be heated via a heating blanket adapted to exhaust filters, or cooled down using a condenser to prevent filter clogging due to condensation. 5. Dissolved Oxygen control a. The dissolved oxygen must be controllable between no less than 5% (minimum value) and at least 100% air saturation (maximum), with a precision of +/- 5% at a 40% air saturation setpoint b.

This procurement is subject to the following trade agreement(s): o Canadian Free Trade Agreement (CFTA) o Revised World Trade Organization - Agreement on Government Procurement (WTO-AGP) o Canada-European Union Comprehensive Economic and Trade Agreement (CETA) o Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) o Canada-Chile Free Trade Agreement (CCFTA) o Canada-Colombia Free Trade Agreement o Canada-Honduras Free Trade Agreement o Canada-Korea Free Trade Agreement o Canada-Panama Free Trade Agreement o Canada-Peru Free Trade Agreement (CPFTA) o Canada-United Kingdom Trade Continuity Agreement (Canada-UK TCA) o Canada-Ukraine Free Trade Agreement (CUFTA)
5. Justification for the Pre-Identified Supplier: Eppendorf is the Original Equipment Manufacturer. They are the owners, developers of the equipment and owners of the IP. They do not authorize value-added resellers or distributors for their equipment. Eppendorf is the sole distributor of its DASGIP bioreactor system for cell culture.
Eppendorf has been selected for this procurement as there are no other sources of supply that satisfy NRC’s requirement for this purchase. No other supplier could be identified that can provide an 8-parallel bioreactor system of the intended scale (0.35 – 1L), that can operate both fully single-use (i.e. no need for sterilizable probe for pH and Dissolved oxygen control) as well as glass vessels, and that can fit within the space constraints of our Biosafety containment level 2 laboratory: 72 inches width, 32 inches depth and 81 inches eight. All these constraints are essential, since it will allow the operation of this system in the NRC’s current laboratories, under a segregated space to prevent biosafety issue, and the use of either single-use or glass vessels will allow this equipment to support both client-focused project, as well as internal and academic research projects.
Only one vendor is able to meet the unique technical requirements listed herein. The following exception to the Government Contracts Regulations is invoked for this procurement under subsection 6 (d) as only one supplier is capable of performing work.
