Purple Cardiology Stethoscope — Bell & Diaphragm | Apex Nocturnal Purple

Apex Symphony Cardiology Stethoscope — Nocturnal Purple (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. Prefer a purple stethoscope? Nocturnal Purple belongs to the 0300 world — the shift that runs on low light and sharp ears.

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 on nights — progressive care, tele, the ICU at 0300 — the Symphony supports the quiet, careful assessments that night shift does more of than anyone. As a stethoscope for doctors, PAs, and NPs, the bell-and-diaphragm design carries nuanced cardiac and pulmonary exams end to end. Nocturnal Purple is for the clinician who wears the night shift with pride.

Care & use

• Wipe diaphragm, bell, and headset with mild soap and water; let parts dry fully.
