4.0 Safety Instructions

Before you connect up the power cable to the mains supply, check that:

the voltage and frequency of the mixer/shaker conforms with the line

voltage (the voltage rating of your mixer/shaker is printed on the

nameplate).

the power switch is set to "0" and the control knobs have all been turned

counterclockwise up to the stop. This will prevent spills due to sudden,

overly vigorous shaking.

The mixer/shaker is not protected for use in explosive atmospheres. Be careful when

using it close to flammable and explosive substances.

The laboratory table must be strong and have a flat and non-slip surface.

Before you start up the mixer/shaker, make sure that the vessel (process medium) is

secure and cannot slip.

Take precautions to prevent attachments or vessels colliding with other objects on

the laboratory table during the shaking operation.

To guard against splashing and spills, close the shaking vessels carefully. When you

work with open vessels, select the shaking frequency accordingly.

To prevent unintentional violent shaking, it is always advisable to start with a low

shaking frequency and to increase it gradually in small steps until you reach the

shaking effect you want.

Always place single vessels at the centre of the platform. When working with several

vessels, always distributed them evenly over the platform.

Consult the load curves whenever you work with high loads and high shaking

frequencies.

Observe the pertinent safety regulations when working with

hazardous media.

Make allowance for the angle of inclination when using tall vessels .

5.0 Installation in the Laboratory

Use the supplied power cable to connect the mixer/shaker to the mains supply.

The appliance connector socket is at the rear.

The mixer/shaker is protected by bipolar fuses. The fuses are located in the housing of the

appliance connector socket and can be reached from the outside. The fuse rating is printed on

the plate.

For a description of how to operate your mixer/shaker, turn to the section "7.0 Operating the

mixers/shakers" and look up your particular model variant.

When working with low shaking frequencies, you can place flat vessels, e.g. Petri dishes, on

the platform without an additional fixture.

This mixer/shaker is fitted as standard with a EURO plug (DIN 49441 CEE 7/VII 10/16 A

250 V). For North America it comes with a US standard plug (NEMA Pub. No. WDI-1961

ASA C 73.1 - 1951 page 8 15A 125 V).

To connect the mixer/shaker to a different mains system, you must use an authorized adapter

or you must have an electrician replace the supplied plug with a suitable 3-pin plug

authorized for your mains system. In its delivered condition the mixer/shaker is earthed! If

you replace the original plug, make sure that the protective earth conductor of your

mixer/shaker is connected to the new plug.

Note the following colour codes if you ever use a different power cable or make any changes

to the power cable supplied:

GREEN/YELLOW = protective earth conductor (PE)

BLUE = phase (N)

BROWN = phase (L)

IN THE UNITED KINGDOM IT IS COMPULSORY TO USE AN APPROVED

STANDARD 13 A PLUG IN CONFORMANCE WITH BS 1363 (3-PIN PLUG).

6.0 Assembly and Description

All BIOMETRA models of this series are stable and rugged shakers and mixers for maximum

performance. They have been developed specially for the shaking and mixing of substances

for scientific purposes in laboratories. Control knobs are neatly arranged at the front for

convenient operation.

With the delivered models there are no shaking frequency limits provided if they are loaded

centrally as recommended.

Mini Rocking Table WT16

The Mini Rocking Table WT16 is used for the shaking of vessels - particularly flasks,

bottles and dye pans - with a gentle rocking motion.

Vessels are placed on the rubber pad that is supplied with the mixer/shaker.

The rubber pad is easy to replace.

Vessels must be secured to the shaking platform in central position and evenly spaced.

Shaking frequency is adjustable from 2 to 50 cycles/min. See Figure 2 for scale values.

The angle of inclination is 5° or 10°, depending on the model..

Mini Tumbling Table WT17

The Mini Tumbling Table WT17 is used for the shaking of vessels - particularly flasks,

bottles and dye pans - with a gentle asymmetrical motion.

Vessels are placed on the rubber pad that is supplied with the mixer/shaker.

The rubber pad is easy to replace.

Shaking frequency is adjustable from 2 to 50 cycles/min. See Figure 2 for scale values.

The angle of inclination is 5° or 10°, depending on the model.

7.0 Operation

The following controls are situated on the front panel from right to left

2-pole power switch with green illuminated rocker (1/0)

Speed control knob (Speed)

Use the power switch to turn the mixer/shaker on. Use the speed control knob to set the

shaking frequency you require. For exact shaking frequency settings, consult the graph

provided for each model.

8.0 Dismantling, Transportation and Storage

DISMANTLING

1. Switch off the mixer/shaker and remove the plug from the socket-outlet.

2. Remove all items of equipment from the vicinity of the mixer/shaker so that it can be

dismantled without difficulty.

3. Remove all vessels from the mixer/shaker. Dismantle any accessories.

TRANSPORTATION AND STORAGE

To prevent damage, it is best to store and transport the mixer/shaker and its components in

their original packaging or other suitable container. Close the packaging with adhesive tape.

Store the mixer/shaker in a dry place.

CAUTION: Guard the instrument from impact and vibration during transport.

9.0 Routine Cleaning and Maintenance

Clean the housing and surface of the mixer/shaker with a damp cloth (mild suds).

IMPORTANT: Never clean the mixer/shaker with chlorine bleach, detergents based on

chlorine, scouring powder, ammonium, cleaning wool or agents with

metallic constituents. This would cause damage to the sensitive surface

of the equipment.

The mixer/shaker has no wearing parts and requires no maintenance. If your BIOMETRA

product ever needs to be repaired, you should enlist the services of a specialist who has been

authorized by BIOMETRA to carry out such work. Contact your local BIOMETRA dealer or

get in direct touch with BIOMETRA.
