Why Dan Logitech?

Glassco: Structural Excellence

Woven Glass Fiber ensures no direct element-to-flask contact, preventing thermal shock. Chemical-resistant powder coating protects the housing against corrosive spills.

Dan logitech: Intelligent Control

Proprietary PID algorithms eliminate overshoot. Dual-display monitoring (Set Value vs Process Value) ensures your reaction stays within safety parameters.

Reliability Testing

Every unit undergoes a 48-hour burn-in test. CE and ISO certifications come standard for all global laboratory compliance requirements.

Exporting Innovation

NABL, ISO, and CE certified instruments for pharmaceutical R&D, chemical synthesis, and petroleum testing worldwide.

CORE LABORATORY APPLICATIONS

Distillation & Fractionation

Essential for separating components based on volatility. Our mantles provide the uniform heating necessary to maintain a constant boiling point, crucial for high-purity fractionation.

Reflux Reactions

For organic synthesis requiring long-term heating without solvent loss. The PID controllers prevent thermal runaway, ensuring stable reflux conditions for hours or days.

Soxhlet Extraction

Widely used in food science and environmental testing. Our multi-position 'Extraction Banks' are specifically designed to house Soxhlet apparatus with dedicated control for each flask.

Vacuum Distillation

Heating heat-sensitive compounds at lower pressures. The precise voltage regulation of our analog series allows for the delicate 'nudging' of temperatures required under vacuum.

Why Glassco Power Elements Outperform Competitors

At the heart of every Danlogitech heating mantle is our glass fibre yarn knitted mantle that ensures uniform, contact-free heating of the flask. The woven glass fibre acts as a thermal buffer — eliminating hot spots and preventing the thermal shock that causes flask breakage and sample degradation.

Safety is built into every BlackDiamond series mantle. The patented spill-collect system contains spillage from flask breakage up to 5 L within the mantle body. The PRO series (1225) adds dual PT sensors that independently cross-check temperature readings — triggering safe shutdown if either sensor reads an anomaly.

Internal Earthing

Integrated grounding throughout the element net and housing prevents electrical surges in case of liquid spillages or flask breakage.

PID Intelligence

Our microprocessor controllers utilize auto-tuning PID algorithms to eliminate temperature overshoot, protecting sensitive samples.

TECHNICAL FAQ

Can the mantles operate continuously for 24/7 distillation?

The industrial analogue series (1220 — 10,000 ml and 20,000 ml) is rated for continuous operation. For long-term programmable cycles in smaller sizes, the Advanced Digital PRO (1225) with its timer and dual-sensor safety system is the recommended choice. The timer can be set from 1 min to 99:59 min with automatic shutoff.

Is it possible to use flat-bottom beakers?

No. All heating mantles are designed strictly for Round Bottom (RB) Flasks conforming to DIN 12347 to ensure proper surface contact.

For flat-bottom glassware, please enquire about DAN Logitech Hotplates (series 500B, 900) or the Digital Dry Block Heater (series 740/750).

What happens if chemicals spill into the mantle?

The patented spill-collect system on all BlackDiamond series mantles is designed to contain spillage from flask breakage up to 5 L within the mantle body. The glass fibre heating net is chemically inert to most organic solvents. Switch off power immediately and dry-clean before reuse.

What is the actual stirrer speed on heating mantle models?

All stirrer-equipped heating mantles (series 1221, 1223, 1225) provide a maximum of ~800 RPM variable electronic stir control. The PRO series (1225) offers step control in 50 RPM increments from 50–800 RPM. Note: standalone DAN Logitech hotplate stirrers (series 500B, 900) reach up to 2,000 RPM — these are different products.

What voltage variants are available for export?

All BlackDiamond series are available in both 230V/50Hz (DNEU item codes — Europe, India, Middle East) and 115V/60Hz (DNUS item codes — USA, Americas, Japan). Both are production-standard. Specify voltage when placing an order. Example: 1222.DNEU.04 (1000 ml, 230V) vs 1222.DNUS.04 (1000 ml, 115V).
