Microwave digestion is a common digestion method in sample pretreatment. Currently, the commonly used microwave digestion brands in the market include CEM, Antonpa, Milestone, Xinyi, Yiyao, Xintuo, etc. As a consumable, laboratory managers often face the pressure of high consumable costs when choosing to purchase microwave digestion tubes.

The domestically produced "super digestion tubes" emerging in the market claim to have similar performance but much lower prices. Is this a "cost-effective choice" or a "hidden trap"?

Actually, the answer is yes!

Core advantage: Significant cost advantage.The direct purchase price is usually only 1/3 to 1/2 of the original price, which can greatly alleviate the pressure of high consumable procurement costs for budget constrained laboratories or routine digestion tasks.

Technological progress:Domestic microwave digestion tubes are made of imported TFM material, which is comparable in product quality and usage effectiveness to imports.

Applicable scenarios:ForLow pressure requirements, simple acid system, mild sample matrix, and low digestion frequencyFor daily testing work, some high-quality domestic pipes can provide acceptable solutions.

Anton Paar's super microwave digestion tube is itsMultiwave seriesThe core consumables of high-pressure microwave digestion system. These digestion tubes are designed specifically for handling extremely difficult to digest samples and applications that require ultra-high pressure/temperature.

1. 8 mL super digestion tube

Model/item number: Typically Multiwave 7101/7301/7501

Key Features：

volume8 mL (sample+reagent volume is usually recommended to be 2-3 mL).

MaterialImported TFM material (a type of advanced modified PTFE)

Sealing methodUse specially designed "spring caps" or "snap caps" for sealing to ensure a tight seal under pressure.

Application Scenarios：

Materials that are extremely difficult to digest (such as catalysts, ceramics, minerals, alloys).

Samples that require ultra-high acidity and digestion.

The research work with the strictest requirements for digestion conditions and safety

2. 18 mL super digestion tube

Model/item numberUsually:MG155.

Key Features：

volume18 mL (sample+reagent volume is usually recommended to be 5-7 mL).

MaterialSimilar to the 8mL tube, imported TFM material.

Sealing methodThe same "spring cap" or "snap cap" sealing system as the 8mL tube.

Application Scenarios：

Need to handle difficult to digest materials with slightly larger sample sizes (but still high difficulty).

Provide greater operational flexibility while maintaining digestion performance.
