The intelligent graphite digester adopts a high-throughput 56-hole design to realize rapid batch pretreatment of massive samples for high-volume digestion laboratories. It uses high-purity graphite as heating medium with inter-hole temperature difference ≤±1.5℃ for outstanding temperature uniformity. Wireless Bluetooth control isolates operators from corrosive acid fumes and high heat for improved safety. Simple operation and fast digestion make it an ideal pretreatment instrument for elemental analysis of various samples.

1. Full Color Touchscreen Operation
   Equipped with tablet-style true color touch panel; no internal wiring connectors or physical switches required for full temperature control, delivering a modern, smooth user experience.
2. 3D Surround Uniform Heating for Higher Digestion Efficiency
   High-purity graphite block features superior thermal conductivity to deliver consistent heat to all digestion tubes without cold zones. Stereo wrap-around heating minimizes heat loss and compensates the shortcomings of flat heating plates.
3. Excellent Sample Repeatability
   Inter-hole temperature deviation ≤±1.5℃ ensures identical digestion conditions for every sample, guaranteeing high precision and accurate test data.
4. Multi-Hole High Throughput, Far Larger Batch Capacity Than Microwave Digestion
   Mass sample processing drastically shortens overall pretreatment time. Standard configuration: 56 holes for 56 × 100 mL liquid samples. Customizable options: 72 / 90 / 110 hole modules. Atmospheric digestion design provides safer and faster operation compared to high-pressure microwave systems.
5. Premium Corrosion-Resistant Construction, Low Maintenance
   Graphite block coated with PTFE coating for easy cleaning and strong acid/alkali resistance. PTFE worktop with zero exposed metal components around the unit, safe for harsh corrosive laboratory environments.
6. Android OS + Expert PID Temperature Control System
   Intuitive visual monitoring via PDA-style interface displays real-time digestion parameters including running time, hold duration and current temperature. Users can edit, save and recall customized digestion programs for different matrices.
7. Genuine Sample Temperature Monitoring
   Optional external temperature probe accessory measures actual sample liquid temperature to guarantee complete, thorough digestion.
8. Proven Reliability with Established Market Reputation
   12 years of market verification with hundreds of end users; widely recognized for exceptional long-term stability and consistent performance.

1. After each experiment, turn the energy adjustment switch to OFF before cutting the main power supply.
2. If the instrument will not be used for a long period, unplug the mains plug, store the digester in a dry environment and cover with a plastic dust cover.
3. Thoroughly clean all surfaces before any maintenance or repair work.
4. Preserve the original operation manual for reference during daily use.
5. The manufacturer shall not be liable for property damage, personal injury or equipment failure caused by unauthorized modification of built-in safety protection devices.
6. No liability will be accepted for losses arising from failure to comply with stated safety preventive measures.
7. Defects and malfunctions caused by careless operation or violation of manual procedures are not covered by manufacturer liability.
8. When rapid heating to target temperature, avoid holding the power dial at FULL position for more than 20 minutes continuously; adjust to gear 1–5 according to actual working requirements.
9. Carry out regular inspection and maintenance to verify all functional parts operate normally, including surface cleaning and safety performance checks.
10. For surface cleaning, use standard laboratory neutral detergents and industrial clean water.

1. Microwave digesters support high-pressure high-temperature reactions that graphite digesters cannot perform. Meanwhile, intelligent graphite digesters operate under normal atmospheric pressure to complete acid removal and open-vessel digestion tasks unavailable for microwave equipment. The core wet digestion chemical principles of both instruments are largely identical.
2. Graphite digesters allow supplementary acid addition mid-experiment; microwave digesters require full cooling and opening the vessel to add reagents after a complete digestion cycle.
3. For samples without high-pressure reaction requirements, graphite digesters can fully replace microwave digestion systems for routine pretreatment.
4. Throughput gap: Microwave digesters process far fewer samples per batch compared to high-hole graphite digesters.
5. Cost difference: Anti-explosion microwave digestion systems generally cost 50,000–60,000 RMB or over 100,000 RMB on the market.

Graphite digesters and microwave digesters serve complementary laboratory roles. Microwave equipment enables high-pressure high-temperature digestion, while graphite systems handle atmospheric digestion and post-microwave acid removal workflows, sharing nearly identical sample digestion chemistry principles.
