Pipeline blockage: Check if the vent valve is open, and use compressed air to back-purge the vacuum pipeline to remove particulate blockage. II. Heating runaway (temperature deviation > ±5?) Characteristics: The actual temperature far exceeds the set value, and the sample boils and splashes out. Solution: Temperature ...
Insufficient pressure not only prolongs the concentration time but may also cause the target substance to degrade due to prolonged exposure to air. Water Bath Temperature Control: The water bath temperature determines the balance between solvent evaporation rate and target substance stability. ...
Unlike traditional sensors that often struggle with unstable readings in humid and variable outdoor conditions, the built-in heater and flow sensor provide constant temperature pretreatment and precise sampling flow control, minimizing the impact of high humidity and particle adhesion. ...
Fully automated microwave digesters, as a sample pre-treatment device, are becoming an important tool in laboratories due to their speed, efficiency, and precision. ...
It organically combines the digestion and acid removal processes, achieving fully automated control from sample digestion to acid gas removal. During the digestion stage, the instrument utilizes the excellent thermal conductivity of graphite to rapidly and evenly transfer heat to the sample, ensuring efficient digestion. Graphite is not only ...
The temperature control of vaccines during transportation and storage is very important. ...
Under constant temperature conditions, the drug solution in the syringe is titrated into the sample cell containing the target protein. ...
Sample dimensions up to 25 mm x 50 mm can be measured.Standard Cell Holder – ThermostaticDesigned for incubation or temperature stabilisation from room temperature to ±40°C . ...
Solvent recovery is the process of extracting useful solvents and raw materials from waste or byproduct solvents that are generated during manufacturing processes. The solvents that are used in these situations are often not disposed of or incinerated, but instead recovered and purified, as this saves considerable costs. Used solvents are mostly purified by means of distillation. Solvent ...
History of ASTM International The American Society for Testing and Materials (ASTM) is an organization that currently provides over 12,500 international standards. Its roots date back to 1898, when ASTM was formed by a group of scientists and engineers to address the frequent rail breaks affecting the fast-growing railroad industry. The group developed a standard for the steel used to fabricate ...
What is a lubricant? A lubricant is defined as a petroleum-derived product used to control and reduce the friction and wear of moving machinery parts (e.g., in engines and turbines). The main purpose of lubricants is to help protect and prolong the lifetime of the ...
While the capillary viscometer suffers from difficult and lengthy procedures for calibration, cleaning, and temperature control, the rotational viscometer is hindered by its rotating parts and delicacy. ...
Direct steam injection into cold fluids in an empty pipe is thermally efficient, but results in other serious problems associated with vibration, noise and poor temperature control. Dispersing steam, or some other phase, in a liquid flowing in an empty pipe, with its unpredictable and uncontrolled shear history, results in a very wide bubble or droplet size ...
