Product List
Modular EEG Recording Caps & Utilities

With the help of this single item product list you can compile any desired combination, or we send you a quote.

See last section for standardized Ready-to-use Cap Sets.

See Electrode Arrangements for various useful Setups and different systems of electrode placement.

	CAPS FOR ADULTS

encompass the sizes (= head circumference) 54, 56, 58, 60, 62. With two sizes, best choose 54 and 58, as third size choose 60.

	CAPS FOR CHILDREN

encompass the sizes 50 (5 years), 52 (approx. 6 years), 54 (9 years) and 56.

	CAPS FOR INFANTS

cover the sizes from 36 (newborn), 38, 40 (3 months), 42, 44 (7 months), 46, 48 (3 years) to 50.

With two cap sizes for every age range you will cover 70% of subjects, with three sizes over 95%.

Please give the size instead of the # (e.g. SU-58).

SU-#

Subtemporal cap

Modular EEG Recording Caps are made in every desired electrode configuration and for all ages from newborn to adult.

Adaptors are usually mounted in the cap by us. However, if necessary adaptors can also be placed on the skin with washers. Further, new adaptors can be added to the cap by the user himself.

This figure also shows, how can incorporate sites for HEOG or on T1/T2.

ADAPTORS

are necessary to mount the electrodes onto the cap or - with washers - onto the skin. When ordering caps, please always specify, where to mount the adaptors. Either choose a montage from our booklet Electrode arrangements or specify your own electrode sites.

ELECTRODES

Electrodes have to be ordered together with the specification of the correct termination and the leadwire length (from 100 to 200 cm).

Terminations:

S = 1,5mm touch-proof safety socket (e.g. B10-S-200) P = 2mm-pin (e.g. B10-P-120)   Other terminations on request.

EAR-ELECTRODES

For attaching electrodes to the earlobes we don’t use clips with springs but rather a „mini-clamp“. This technique exerts a static pressure and therefore doesn’t hurt. Since you cannot use ring electrodes for this we provide them with conventional electrodes.

C2

(Cable length and termination will be made to match your other electrodes)

To attach the mini-clamps affords a little practice. As an alternative we therefore offer conventional ear clips too. For those, hat-shaped electrodes with flat rim are required (e.g. electrode E220X, see below).

ELECTROLYTES

V14

Lectron II, tube á 250 grams

Chloride-free electrolyte gel

This chloride-free gel supports the superior qualities of sintered electrodes: it is utmost stable and not influenced by sweat or body warmth. It allows lowest impedances for best signal quality. It is hypoallergenic and chloride free, i.e. suited for sensitive subjects and long term recordings. It is of clear substance, free of odours and water soluble.

For use with children or when no abrasive preparation is necessary:

V15

Lectron III-10, tube á 250 grams

High-chloride electrolyte gel

There are two instances, where chloride-free electrolyte is not recommended: for DC recordings the same ion is required in the electrodes and the electrolyte. In case of Ag/AgCl electrodes that’s salt. Further, one should not switch from chlorided gel to a chloride-free one on the same machine (though the opposite is possible). Therefore we suppy a chlorided gel too. Due to its above-average salt share of 10% lowest impedances are achieved even quicker.

V14

V15

Our recommendation:

ABRALYT 2000, our standard electrolyte, is made of "V14: Lectron II " (see above), to which a gentle abrasive is added, resulting in a high quality electrolyte gel, which at the same time is abrasive. Thus, ABRALYT 2000 saves a step when minimizing impedances.

V17

Abralyt 2000 (1000 gr.)

Chloride-free, abrasive electrolyte gel

V19

Abralyt HiCl (1000 gr.)

High-chloride, abrasive electrolyte gel. This is the abrasive version of Lectron III-10.

V14 and V17 can be used together in the same recording, and also V15 and V19 are compatible to each other.

ELECTROLYTE PASTE FOR SKIN ELECTRODES

These two chlorided electrolyte pastes are suited to place single electrodes onto the head or - combinded with washers - onto the skin.Elefix is easier to remove, while EC2 is recommended for application longer than one hour.

SIGNAL GENERATOR / IMPEDANCE METER

SIGGI basic & SIGGI advanced

Impedance measurement of skin electrodes only yields correct results if done by AC voltage. Moreover, prolonged usage of the DC voltage of a common multimeter will even damage chlorided electrodes. Our SIGGI device allows easy impedance measurement between pairs of electrodes with different frequencies, or to objectively verify the built-in impedance measurement of EEG amplifiers.

To objectively verify e.g. an EEG amplifiers functions, an external signal source with defined output is needed. SIGGI supplies sine- and square waves of different frequencies and amplitudes. Prior to DC recordings it is helpful to check the amplifiers properties by a DC source. Also, the common mode rejection properties of an amplifier should be known. Finally, feeding a real EEG signal into the amplifier can reveal a lot to the experienced eye.

So we unified all these functions in one handy, easy to operate device. It is available as a straight forward version for daily lab requirements - SIGGI basic - and as a reconfigurable version with interface to a PC and a Windows configuration program - SIGGI advanced.
