Yellow Cardiology Stethoscope — Bell & Diaphragm | Apex Neon Yellow

Apex Symphony Cardiology Stethoscope — Neon Yellow (Bell & Diaphragm) is engineered for the widest usable frequency response in our lineup. A precisely machined stainless steel chestpiece pairs a true acoustic bell with a precision-tuned diaphragm, while dual lumen tubing cuts rubbing and ambient noise. From low-frequency gallops to high-pitched murmurs and breath sounds, the Symphony hands you the whole signal. A yellow stethoscope this bright needs no introduction — Neon Yellow says exactly what it is, at full volume.

Why a dedicated bell matters

The lowest-frequency sounds — S3 and S4 gallops, the diastolic rumble of mitral stenosis, vascular bruits — sit at the edge of what a diaphragm transmits. A true bell, rested lightly on the skin, couples directly to those low tones instead of filtering them out. You'll find a heart rate with any stethoscope; it's the faint low sounds, the ones that change the plan of care, that make a dedicated bell worth carrying.

Bell & diaphragm features

• Full-spectrum acoustics: true bell for low-frequency sounds, precision diaphragm for high — no tunable-membrane compromise.
• Acoustic precision: stainless steel chestpiece with a finely finished diaphragm and machined bell rim for a reliable skin seal.
• Noise control: dual lumen tubing limits friction and ambient interference.
• Comfort & fit: angled headset with soft-seal eartips for a secure acoustic seal.
• Daily durability: components selected for routine clinical use and straightforward care.

Designed for nurses and doctors

As a stethoscope for nurses, doctors, PAs, and NPs, the Symphony supports the advanced cardiac and pulmonary assessments where low-frequency findings matter most. In Neon Yellow, it belongs to the clinician who's seen on purpose — the brightest presence on the unit, with acoustics serious enough to back it up.

Care & use

• Wipe diaphragm, bell, and headset with mild soap and water; let parts dry fully.
• Avoid harsh solvents and extreme heat.
• Replace eartips when worn; store without tight bends.
