Nanjing Binzhenghong Instrument Co.,Ltd is a professional laboratory product manufacturer which mainly has laboratory products based on PTFE/PFA/FEP and other materials, such as: beaker/reagent bottle/stirring bar/tweezers/funnel/volume flask/crucible/stirring rod/water tank/reaction bottle/washing bottle/ The measuring cylinders/etc.
Our products are sold all over the world (such as CUG, IGCAS, SGS, etc. )and are well received by experimenters in the semiconductor, electronics, and pharmaceutical industries, and are widely used in the chemical industry.
PTFE digestion tube
PTFE digestion tube is mainly suitable for food, disease control, academy of agricultural sciences, medicine, agriculture, forestry, environmental protection, chemical industry, biochemical and other industries, as well as colleges and universities, scientific research departments for soil, blood samples, urine samples, nails, food, dairy products , Agricultural and sideline products, feed, heavy metals, ores and other chemical analysis before sample digestion treatment, can be used in conjunction with atomic absorption, atomic fluorescence, ICP-AES and Nanjing Binzhenghong heavy metal electrothermal digestion instrument and other analytical instruments.
PTFE digestion tube: PTFE digestion bottle, F4 digestion tube, digestion tank digestion tank, etc.;
Selling point:
1. Customization: PTFE digestion tubes from various manufacturers can be flexibly customized, and PTFE digestion tubes can be equipped according to the size of the graphite digestion instrument
2 The open can withstand 250°C, and the recommended temperature for sealing should not exceed 160°C
3. Low background value: very low dissolution and precipitation
4. The inner wall is smooth and does not hang water
5. Customized specifications, sizes and bottom shapes (sampling processing and drawing processing)
Its main features are:
1. Can withstand -200~250ºC;
2. Strong corrosion resistance, aqua regia, HF, sulfuric acid, hydrochloric acid, nitric acid, acetone, alcohols and all inorganic and organic samples; the tube body has no adsorption, non-stick, convenient for experimental cleaning;
3. There are more transparent PFA digestion tube options: you can observe the changes in the reaction status of the sample during the experiment;
4. It is easy to operate and can also be used as a centrifuge tube. The tube wall does not adsorb organic substances such as hydrophobic substances;
5. It is more suitable for the graphite digestion system of various manufacturers, and the matching effect of my electric heating plate digestion instrument with holes is better;
6. It is mainly used for simple sample pretreatment and heating of samples that are easy to digest (soil, food, medicine, etc.) and simple wet digestion experiments;
7. Generally, when used in a graphite digestion instrument or my perforated digestion device, it is recommended that the customer make a flat bottom, which is convenient for heating and ensures uniform heating; according to the needs of the customer's experimental collection of samples, the inside of the tube body can be processed into a flat bottom or a V bottom. , U bottom three styles;
8. When the customer is using it, some experiments in the heating process need to be airtight. Due to the airtight heating, a certain pressure will be generated inside the tube body at high temperature, which is easy to deform. Therefore, when it is airtight, it is recommended that the customer use the temperature should not be too high. 130-160 degrees and within; similarly, if the customer needs to open the heating, if the cover is not used, it may cause the pollutants in the air to fall into the tube, thereby contaminating the sample being digested. We have improved this, and the design is similar to The polytetrafluoroethylene perforated digestion tube cover of the beaker cover not only solves the disadvantages of closed digestion, but also avoids the secondary pollution caused by air to the sample during open digestion;
