Supply of Chemostats and Bioreactors

In order to develop an experimental system to mimic fermentations in a wide range of gut environments.

we wish to obtain

Up to 8 x chemostats/ bioreactors (priced as separate units)

All systems capable of aseptic operation under both aerobic and anaerobic conditions.

Vessels to have an operating volume of 2 liters or less, each vessel to be supplied with and without a downward sloping side arm output within the operating volume, internal diameter of at least 3 cm.

Each vessel to have independent control and monitoring of;

Agitation via stirring

pH,

dO2 and/or redox

temperature (from RT to 42C)

Gas flow (meter capable of controlling gas at very low flow 2-10 of mL/min)

The top plate must have spare ports capable of accepting additional probes and or inputs that may become available at a later date, in order to keep the systems current (at least 1 additional port with a diameter ~ 20mm with clear vertical clearance to be able to mount and external solid feeder unit to be obtained separately).

A computerised based monitoring system for all vessels and if available a computerised control system.

Optional

Feeding pumps for buffer and outflow controlled directly with the controller or via the computer so every fermenter is truly independent (avoiding use of multichannel peristaltic pump).

Interchangeable vessel to be able to work with volumes of 1-2L and 100-500mL.

Welcome to this etender opportunity.

If you have not used the Bravo Solution etender portal before, you are advised to download the supplier quickstart guide from the attachment section. If you have any queries or questions concerning the tender documentation, you can send these through the portal messaging system.

Please note that this tender comprises a selection of attachments which you can download to read and, typically, three ‘envelopes/questionnaires’ (qualification/technical/commercial response sections).

These ‘envelopes/questionnaires’ are areas where you will find the tender questions you need to answer, typically by attaching responses and/or completing drop down selection boxes or empty fields. Consistent with the text in our advertisement, you will need to ‘reply’ to this ITT in order to gain access to the various envelopes/questionnaires so you can read the questions requiring attention.

If you are intending to submit a response, please ensure you have completed all required actions well before the closing date and time. The ‘read me first’ section in the qualification response envelope/questionnaire contains some helpful notes and reminders for you, in this regard.

You will need to make sure you have answered all mandatory questions (i.e. anything marked with a red *) and also uploaded any general attachments that you also wish to bring to our attention.

IF YOU DO NOT COMPLETE ALL REQUIRED ‘INLINE’ ATTACHMENTS AND/OR DROPDOWN/OPTION MENUS AND/OR EMPTY FIELDS AND/OR ANY OTHER MANDATORY OPTIONS WHICH WE HAVE USED (DENOTED BY THE RED * IN EACH CASE) IN THE QUALIFICATION, TECHNICAL AND COMMERCIAL ENVELOPES/QUESTIONNAIRES (AS APPROPRIATE) THEN, AS WE UNDERSTAND IT (WE CANNOT SEE THE BIDDERS SIDE OF THE SYSTEM, TO PROTECT TENDER INTERGRITY) THE SOFTWARE WILL NOT ALLOW YOU TO SUBMIT YOUR BID.
