Ultrasonic Bath

Item Code:HL-1306

the laboratory and pharmaceutical sectors are industries which benefit from the incorporation of ultrasonic’s into cleaning and processing applications. Testing in laboratories requires stringent cleaning measures and processes, while the repeated manufacture of pharmaceutical products must ensure that no residues or contaminants are left on equipment.
laboratory
in much the same way that a hospital uses its instruments, a laboratory will require a cleaning system to ensure that items are completely clean and free from contaminants prior to each use. Any residue or debris left from previous processing could provide inaccurate and incorrect testing results. The use of delicate instruments in the laboratory makes ultrasonic’s a perfect technology
for cleaning and reprocessing. The gentle yet effective cleaning action ensures that contaminants are removed but instruments are not damaged. Also use for washing of laboratory glassware, ceramic components (mortars), and plastics components. Besides time star cleaners can also used for "sonochemestry" application, acceleration of chemical process, solution degas for hplc technique.
