Couldn't load pickup availability
Analog capillary melting point apparatus for organic chemistry teaching, pharmaceutical QC, and material identification, ambient to 350°C range with energy-regulator temperature control. Aluminum cylindrical heating block with radial holes accepting 3 capillary tubes and mercury/digital thermometer. Illuminated observation window (lamp underneath block) for shadow-less viewing of sample as it melts. Energy regulator with high/low heat switch for controlled ramp rate. Includes 100 capillary tubes. $214.99 direct, the essential undergraduate and industrial teaching / QC melting point tool. Premium OEM automated MP apparatus (Buchi B-540, Stuart SMP20, MPA100) run $2,500-$8,000; this analog unit delivers the fundamentals for teaching and basic pharma QC at 3-8% of that cost.
Applications
- Organic chemistry teaching: undergraduate identification of synthesized compounds by melting point (universal chem lab experiment)
- Pharmaceutical QC: API identity and purity verification per USP <741> Melting Range or Temperature
- Nutraceutical and supplement manufacturing: raw material identity confirmation
- Ayurvedic and herbal ingredient identification: Bhasma / Rasa Aushadhi purity check
- Forensic chemistry: unknown solid identification
- Perfume and essential oil QC: solid fragrance component verification
- Wax and polymer characterization: melting range assessment
- Food and confectionery QC: fat, chocolate and wax melting point verification

Analog vs Automated Melting Point: Which Do You Need?
Analog (this instrument) = manual observation, operator watches sample and records temperature when melting begins/completes. Fully valid per USP <741>. Best for: teaching, small pharma QC, budget-conscious labs. Automated (Buchi B-540 / Stuart SMP20 / SciMed MPA100 $5,985): digital camera detects melting inflection points, records precise mp values, prints reports, LIMS integration. Best for: high-volume pharma production QC, GMP-regulated pharma release testing, method validation. If you need SciMed's automated tier, see the MPA100 Automated Melting Point Apparatus.

Frequently Asked Questions
Is thermometer included?
NO, thermometer sold separately. Standard partial-immersion mercury thermometer 0-360°C with 76mm immersion required. Digital thermometers also compatible. Order thermometer and this MP apparatus together, email us for pairing.
USP <741> compliance for pharma?
Yes, capillary method with visual observation is one of the approved USP <741> methodologies. Data acceptable for compendial pharma release testing. For GMP-regulated production QC, LIMS integration and audit trail, invest in automated (MPA100 tier).
How long do capillary tubes last?
Single-use, one capillary per determination. 100 included covers ~30-50 determinations (typical duplicate and reference standard runs). Replacement 500-pack ~$15 direct.
Heating ramp rate?
Operator-controlled via energy regulator. USP recommends 1°C/min near the mp. This unit allows manual adjustment, turn regulator down as sample approaches expected mp for compliant ramp control.
