Installation
To use
Media Pump
at its best, we suggest installing it on a stable, flat and rigid surface.
Example with bottle container: Example with broth bag:
Put the tube into the peristaltic pump (from front to back). Be careful to center it to avoid pinching the tubing
when closing the pump. (BE CAREFUL: carefully read the tubing installation guide provided).
When the pump is opened, you must adjust it according to the inner
diameter of the tubing by moving the rotating button.
Turn the wheel on each side of the pump to get the correct setting
according to the diameter (1.6 / 3.2 / 4.8 / 6.4 / 8 mm) and the
thickness of the tubing (1.6 mm).
Insert the tubing into the pump.
Keep the tubing stretched while you close the pump.
WRONG
RIGHT
The tubing is pinched.
It can be pierced.
The tubing is not pinched.
There is no risk.

Intended use
Media Pump is a programmable peristaltic pump designed for liquid distribution from 50 µL to 99 liters. It
dispenses manually or in serial dispensing agar, diluents or any other liquid. With a precise and repeatable flow,
Media Pump is a great tool for filling tubes, containers, broth bags and Petri dishes preparation.
With a user-friendly interface and great ergonomics, Media Pump guarantees an efficient and precise lab work.
It is also very compact, only 16 cm width, and easily fits under a PSM hood. The equipment is robust with a
stainless steel and heavy-duty polycarbonate top shell, designed to last long.

Overview
Description of Buttons and Switches
Front View of Media Pump
Button and a few other buttons.
The general use of Media Pump is easy. The front panel is composed of a screen, a rotating button
and a few other buttons.
Information and menus appear on-screen. The rotating button at the right side of the screen is the
main control of the Media Pump: it allows you to choose the options and launch the operations
(e.g. dispense liquid, calibrate or set a program).
The other buttons have specific functions. They act as shortcuts for specific actions. For example:

Menu
A menu is a list of choices appearing on-screen. The user turns the rotating button to look at the menu
and presses the button to validate their choice. If the list is too long to fit on the screen, the list scrolls
as the user turns the button.
Example of the main menu, when the Media Pump is turned on:
The on-screen menu is hierarchical: the user can, when choosing an option in the menu, go to another
menu, called sub-menu. For example, the option “MODIFY PROGS“ of the main menu leads to the
following sub-menu:
At any time the “esc.” button allows the user to quit the on-screen menu and go back to the main menu
or the top menu.

Getting Started
Principles of use
Media Pump has 3 dispensing modes: continuous, dose and multi-dose.
Continuous mode:
In this mode, the user controls (by hand or by foot) the starting and stopping moments of the pump. The pump
speed controlling the flow is initially programmed by the user.
Dose mode:
In this mode, the user controls (by hand or by foot) the starting moment of the pump. The pump immediately
stops when the programmed volume is dispensed. The pump speed and the volume to distribute are initially
programmed by the user.
Multiple-dose mode:
In this mode, the user controls (by hand or by foot) the starting moment of the pump for the first dose. The pump
automatically stops when the programmed volume is dispensed. Then it automatically dispenses again after a
programmed delay. The user programs the speed of the pump, the volume to dispense, the number of doses and
the delays between initially.
Principles of operations
Media Pump is a peristaltic pump controlled by a microprocessor.
When a dispensing is programmed, the microprocessor controls the pump in movement and stops it when the
pump has done the asked number of rotations.
A calibration operation is necessary to set and memorize the number of necessary rotations.
Concept of program
Media Pump is a programmable equipment.
The user can choose their preferred programs and memorize them.
Each preferred user mode, (for example 9 mL in mono dose at a 3 mL/s flow) is then called a program. The user
can then enter other programs and name them so they can easily distinguish them.
Media Pump is delivered pre-programmed with the following programs:

10 vwr.com I Instruction manual VWR®Media Pump
• tube 9ml: distribution of 9 mL doses
• 18ml dishes: distribution of 18 mL doses
• multi 9ml: multiples 9 mL doses
• bag: distribution of 225 mL doses
• Continue: continuous and fixed flow
Important Guidelines
Advice for the choice of a tubing
Media Pump can be equipped with tubes with various diameters if you have several tubes and wish to change it
according to your application: either specific flow or viscosity.
Please keep in mind that a program is made to function with a predetermined diameter tubing. The flow
distributed by the pump depends on the tubing's diameter and its speed fixed by the program.
During the liquid flow the inner diameter of the tubing is important to get a good precision. The bigger diameter
on the tubing, the faster the flow (mililiters per minute) and less it will be adapted for dispensing of little volumes.
On the side of the Media Pump is engraved 1 diagram. It shows the precision that you can get according to your
volume and the inner diameter of the tubing.
Example, with the Media Pump:
How to read the diagram:
For a given tubing diameter, the curve indicates the guaranteed precision according to the volume of a dose.
Example: in this figure, for a tubing with inner diameter of 4.8 mm (red curve) and a volume of 9 mL, the
guaranteed precision is inferior to 4 % (follow the dots in red). On the contrary, knowing the volume of your dose
(for example 9 mL) and the maximum precision you want (for example 2%) – (follow the dots in black) -, a tubing
with an inner diameter of 3.2 mm is sufficient because its curve goes underneath the intersections (lines in dots).
Note: the lines in black dots are engraved on the side of the Media Pump, but not the red ones.
9 mL = typical volume to dilute a 1mL sample at 1/10th.
18 mL = typical volume to fill a 90 mm Petri dish with agar.
225 mL = typical volume to dilute a 25 g sample at 1/10th.
