2.2.2 Reagents Setup
This menu allows the user to access the Reagent menus.
1. Install New Reagents. Menu used to install and prime the reagents in the BioTector. Any “85_Reagents
Low” and “20_No Reagents” warnings and notifications can also be reset in this menu.
2. Purge Reagents & Zero. Menu used to purge the reagents, and carryout a zero calibration cycle.

The install new reagents procedure is an automatic procedure for installing new reagents, setting the zero
offset by Zero Calibration cycle, setting the reaction check levels and checking the span by Span Calibration
or Span Check cycles. Span Calibration or Span Check cycles are part of the Install New reagents sequence
if SPAN CALIBRATION or SPAN CHECK is activated in New Reagents Program menu. The basic Zero
Check/Calibration and Span Check/Calibration parameters (operation ranges, number of reactions, standard
solution concentrations etc.) are programmed in Zero Calibration and Span Calibration menus respectively
(see Section 2.3 Calibration Menu for details). The comprehensive Zero Check/Calibration and Span
Check/Calibration parameters are programmed in Zero Program and Span Program menus respectively (see
Section 8.3.4.2 Zero Program and 8.3.4.3 Span Program for details).
To run the Install New Reagents cycle, the BioTector must be stopped. Confirm that all or the corresponding
new reagents have been installed on the BioTector, for instance for acid reagent, select New Acid Connected,
and press the ENTER key. A tick mark will appear as confirmation that the new acid has been connected.
Note that when one or more reagent volumes are updated in Reagents Monitor menu, system automatically
resets the new reagents volumes in this menu and also updates the figures displayed in the main Reagents
Status screen.
All reagents volumes can be reset while system is running. This function allows the user to top up the
reagents without stopping the system. However, when acid and/or base reagents are replaced or topped up,
system requires a new Zero Calibration cycle. A “ZERO CALIBRATION REQUIRED” warning will be
displayed on the screen when RESET ACID MONITOR and/or RESET BASE MONITOR are selected.
Therefore, it is strongly recommended to stop the BioTector and activate the Start New Reagent Cycle or to
run the Zero Calibration cycle using the Zero Calibration menu. If DI Water is used during the Zero
Calibration/Check cycles (see ZERO WATER in section 8.3.4.2 Zero Program for details), and when “NEW
ZERO WATER (DIW) CONNECTED” message is displayed in this menu, it is important that Zero Water (DI
Water) is connected to BioTector’s Zero Water port or Manual/Calibration port (if these ports are not available,
connect DI Water to Sample 1 port) before the Install New Reagent cycle is started. Failure to do so may
have an impact on system zero response and the analysis results.
