1.2 Safety
1.2.1 Intended use
1.2.1.1 Liquid Handling Station
The BRAND Liquid Handling Station is a pipetting robot for use in routine laboratories with small and medium sample throughput in research, development, and  production, especially in fields of application like PCR, qPCR, ELISA, enzyme tests, etc. The device is typically used to pipette aqueous media such as buffer solutions (phosphate buffer, Tris/HCl buffer, etc.), protein solutions (BSA solutions, enzyme solutions, PCR master mixes), and aqueous media and samples.
The device is used for the automatic, precise transfer of liquids. For the liquid transfer, autoclavable 1-channel and 8-channel pipetting modules (Liquid Ends) are available  that must be changed manually. 7 SLAS work stations (P2-P8) can be freely equipped on the work table. An additional predefined work station (P1) must be assigned with the waste container.
1.2.1.2 Liquid Handling Station flow
DANGER
Use of harmful substances, infectious liquids or flammable media
When working with the FlowBox, a continuous stream of air is blown out of the pipetting robot into the environment. This air may contain harmful or infectious aerosols.

• The FlowBox may not be switched on if you work with biohazardous, radioactive, toxic or otherwise hazardous substances!
• Do not use any media in the work area and in the area around the FlowBox that may generate strong heat in a reaction or form a potentially explosive atmosphere. Examples: Acid-base reactions, carbon disulfide.
• The device must be disinfected prior to using the FlowBox according to the instructions in the chapter Maintenance/Cleaning. If you have any questions, please contact the manufacturer and/or you safety officer.

NOTICE
Turbulence
In order to reduce turbulence, open the front door slowly and as rarely as possible. Also, the protective screen must be inserted.
NOTICE
Regularly exchanging the HEPA filter The HPA filter of the FlowBox gets dirty with time. It is therefore recommended to have the filter changed by a service employee at least once per year. The BRAND Liquid Handling Station flow is a pipetting robot with a permanently installed filter unit, the socalled FlowBox, which purifies the air in the work area of the Liquid Handling Station flow. For this purpose, ambient air is aspirated, filtered, and blown outwards in a laminar flow from back to front across the work table through small openings in the front door. Particles that entered the work area of the Liquid Handling Station flow before switching on the FlowBox are flushed out of the work area through the air stream and the openings in the front door. The filter of the FlowBox is therefore used to reduce the number of particles in the work area. If the front door of the operationally ready pipetting robot is opened, the fan speed and thus the air stream directed outwards from the FlowBox are increased in order to reduce the risk of sample contamination.
1.2.1.3 Usage limits and restrictions

The viscosity of liquids as well as wetting liquids compromise the accuracy, as do liquids whose temperature deviates from room temperature by more than +/- 5 °C.
NOTICE
Risk of corrosion
The device can be damaged by media.

• Do not use the device to pipette liquids that attack polypropylene, PMMA (side and front panel), POM or aluminum (labware adapters).
• Avoid aggressive vapors.
• Avoid strongly acidic or alkaline solutions.

Protect the device from the penetration of liquids. Do not place any vessels containing liquids on or next to the device.
This device can be used in combination with hazardous materials, work processes and equipment. However, the operating manual cannot cover all of the safety issues that may occur in doing so.

Glossary

A
Adapter
Adapters are used to compensate for height differences between the different labware types. They can be used to achieve shorter paths and a faster implementation of the method. The distinction is made between height adapters, tip adapters (for tips), micro-tubes, and PCR racks. Overview of all available adapters, see Ordering Information, p. 84.
C
Command
Refers to a single sequential step in the program sequence of a method. In the operating software, four different commands are generally available: Transfer, Wait, Mix, and Break Command. Additional device commands are available depending on the device type and accessories.
Cooler
Refers to a device used to cool samples.
Content structure
The content structure of a report comprises all the elements between the report header and footer, i.e. the actual (method-specific) content of the report.
D
Destination
Labware or target vessel into which liquid from another vessel (source) is transferred.
Destination well
Single well of labware defined as a destination.
F
FlowBox
Permanently installed filter device that purifies the air in the work area of the Liquid Handling Station flow.
Filling volume
Maximum volume of a labware or an individual well available for filling liquid.
G
Graphical view
Area in software that graphically displays the work table (with selected labware, filling, etc.).
H
Heater and shaker
The term Heater and Shaker refers to the device Teleshake 95, which can be used to heat and/or shake samples over an adjustable period of time. The device is placed at a position in the Work Table and controlled via the Heat/Shake command. The device can also be controlled outside of the Liquid Handling Station Software
in order, for example, to heat samples over a period of time longer than the method sequence.
L
Labware
Collective term for the microplates, PCR plates, deep-well plates, inserts, tube racks, tubes, tips, reservoirs, and waste box that can be used with the Liquid Handling Station.
Liquid End
1- or 8-channel pipetting unit coupled to the motor control unit in order to allow the execution of liquid transfers with the Liquid Handling Station.
Liquid type
Definition of various liquid parameters, such as aspiration and dispensing speed.
M
Master layout
The master layout of a report comprises the report header and footer, as well as general settings for the page layout, e.g. page margins, font size and style in the report. Method Procedure for the loading of the work table, the definition of commands, and the execution of the method. You can find a more detailed explanation of the term “method” in the chapter “Method Structure”.
Minimum immersion depth
(= minimum tip immersion depth). Distance of the lower end of the tip to the liquid surface.
This distance guarantees correct liquid aspiration and prevents, for example, accidental air intake.
Minimum bottom distance
(= minimum bottom distance). Refers to the shortest distance between the vessel bottom and the lower end of the tip moved into the labware during immersion. This distance is used to prevent crashes and to ensure a correct liquid aspiration.
Multidispense
Pipetting mode in which a volume aspired from a source is dispensed into a destination in partial steps.
P
Pipette
Pipetting mode in which a previously defined volume is aspired from a source and then completely dispensed immediately thereafter into a destination.
Pipetting step
The aspiration of a previously defined volume from a source and dispensing of this volume (as a whole or in partial steps).
Position
Individual recess on the work table of the Liquid Handling Station on which labware can be positioned. The work table of the Liquid Handling Station has eight positions. Seven of these can be equipped as desired, while one position is designated for the waste box.
Prewet
Designation for the preliminary conditioning of the tips through liquid aspiration from the source well and subsequent liquid dispensing into the source well.
Priority
Setting option for liquid names in the well content. If the liquid name is given a high priority, this is retained for all methods, i.e. the transfer history of a certain liquid can be  racked.
R
Remaining volume
(= remaining volume). Volume that must remain in the vessel to allow a defined and reliable intake. It depends on the minimum immersion depth and the minimum bottom distance.
Restart behavior
Setting option for liquid volumes. If the method is restarted, the volume remaining from the feed line is used as the starting volume.
S
Sample selection Setting in the Execute tab that enables the reduction of the existing methods to the actual number of accumulating samples.
Settings
Settings that can be made for the labware at the individual positions and for the different commands. Shaker see Heater/Shaker
SMTP settings
Settings for the login of the e-mail service.
Source
Labware or source vessel from which liquid is removed in order to be transferred to another vessel (destination).
Source well
Individual well of labware defined as a source.
T
Tab
Refers to individual tabs on a menu tab. Example: Method tab in the main menu tab.
Transfer
A single transfer includes all the pipetting steps executed between one or more sources and one or more destinations in a (Transfer) command.
Transfer volume
Liquid volume that is transferred from the source to the destination or into the individual wells of the destination.
V
Distribution pattern
Specification of the source wells and destination wells.
W
Well content
In general: The content of one or more wells. In the operating software: Settings (e.g. liquid volume, name, liquid type) that apply to the content of a fillable labware.
Workbench
All relevant data required for using the Liquid Handling Station Software is found in the Workbench. (E.g. labware definitions, methods, user settings, etc.).
Work table
Work area of the Liquid Handling Station whose eight positions can be virtually loaded using the software.
The definition of the commands is followed by the physical loading of the work table.
Z
Z-tracking
Tracking of the liquid end on the Z-axis during liquid aspiration and dispensing. The Z-tracking corresponds to a downward movement during liquid aspiration and an upward movement during liquid dispensing. The starting point of aspirating and dispensing can be user-defined if necessary.
