Instruments for ENT, ophthalmology and dermatology


ri-former® - modular diagnostic station

Thanks to its innovative construction it is variably extendable to the right and the left. The basic ri-former® module is available with one handle and can be supplemented with up to 4 further handle modules. The advantages of the ri-former® system can be seen in its versatile combination of options. The ri-former® offers the required reliability in hectic everyday hospital and practice life, with its centralized electrical supply. Cost-saving and environmentally friendly independence from conventional or rechargeable batteries is thus guaranteed.

uni® / econom®

Riester uni®/econom® – the reliable product line for ENT and ophthalmology. Durable, user-friendly, variable and in the customary Riester quality.

- Illumination of the examination area with 2.7 V vacuum, HL 2.5 V Halogen or xenon illumination XL 3.5 V, similar to daylight.
- Power sources via various handles or charging base ri-charger® possible.
- Choice of sets with exceptional cost-effectiveness.
- Developed and manufactured in Germany.


The new e-scope® is the perfect blend of leading-edge LED technology, more efficient diagnosis and an environment-friendly energy source. Because the e-scope® breaks new ground with its world innovation, the IPC (Integrated Power Converter): younger, smarter and greener.

LED technology for otoscopes and ophthalmoscopes with low-reflection, bright and whitelight. The pure white light (approx. 5,500 K) ensures colour-neutral illumination in additionto improved colour differentiation, thereby aiding more efficient diagnosis in comparison with halogen or xenon bulbs.

Green efficiency
- Low maintenance costs thanks to long LED and battery service lives. Whilst the service life of a xenon light source is only approx. 20 hours, LED burns for at least 20,000 hours, i.e. over 2 years at a go – with e-scope®, even with two conventional AA batteries.

- Particularly high environment-friendliness, for the newly developed IPC in the e-scope® always converts the voltage of simple alkaline batteries into the optimum voltage required for LED operation, resulting in battery lives of around 50 operating hours.

Pocket instruments

The versatile diagnostic penlights made of sturdy material with a wide range of uses fit safely in the hand for every examination. Poorly accessible parts of the body can be better illuminated.

We will be pleased to provide more information about the ordering requirements for customer specific product combinations and packaging upon request.
