RELAX FS ULTRA · No. 4, Ø 22 mm · pack of 10
Every screwed mirror has a seam where the cone meets the handle, and somebody in your practice has to decide what happens to it. RELAX takes the question away: it is moulded as a single piece, with what Hahnenkratt describe as an exactly plane transition from mirror to casing, so there is nothing to unscrew before reprocessing and nothing to reassemble after. This is the FS ULTRA version – their brightest coating, on the standard Ø 22 mm adult head.
This pack: 10 × Hahnenkratt RELAX FS ULTRA Mouth Mirrors, No. 4, Ø 22 mm · one-piece, glass-fibre-reinforced plastic, autoclavable to 134 °C · no separate handle needed
Made by E. Hahnenkratt GmbH, Germany · mfr code 7306
| Made from one piece | Hahnenkratt designed RELAX for an exactly plane transition from mirror to casing. No thread, no seam at the head, nothing to take apart |
| No disassembly | Hahnenkratt state that disassembly for cleaning is not required, and cite the KRINKO recommendation of the Robert Koch Institute as the reason the design matters |
| FS ULTRA coating | Their brighter option, from 36 layer packages – a reflection factor Hahnenkratt put at over 100% measured against aluminium, up to 25% brighter than FS Rhodium |
| 134 °C, 10 per pack | Glass-fibre-reinforced plastic body, autoclavable to 134 °C. Ten to a pack – a set for every surgery rather than a replacement for one |
› Complete as it comes – no handle to buy, no cone to order. Ten mirrors is ten working instruments.
› Coloured bodies – Hahnenkratt make RELAX in seven colours, which is as useful for telling one set from another as it is for a nervous child.
› Front surface – one reflection, no faint second image behind the first, the same optical principle as the rest of the Hahnenkratt range.
› Made in Germany – Hahnenkratt's own description of the range.
One-piece or cone and handle?
One-piece is simpler through decontamination and cheaper per working mirror, because there is no handle to buy. Cone and handle wins on longevity – a scratched head is a few pounds to replace rather than the whole instrument – and lets you mix head sizes on handles you like. ULTRAvision No. 4 is the same size in cone form.
Is FS ULTRA different from the rhodium RELAX?
Yes. Both are front-surface mirrors; the coating is what differs. Hahnenkratt put FS ULTRA at up to 25% brighter than their FS Rhodium. This SKU is the ULTRA.
What if I need a matt instrument for microscope work?
RELAX is not that instrument – go to the DLC-coated BLACK ULTRAretract with a BLACKline handle, or the ULTRAmicro Flex micro mirrors.
