| MICROLAB 600 Diluter & Dispenser FAQs Common Questions How can I determine the accuracy for my Hamilton MICROLAB 600? What can I do if I am getting corrosion and crystallization in my syringe(s) and valve(s) from my saline/salt based solutions? How tight should fittings on the valve be? When will the valve need to be replaced? My MICROLAB 600 is making strange noises, what should I do? How often should I calibrate my MICROLAB 600? How do I clean and maintain my MICROLAB 600? What is the recommended preventative maintenance schedule for the MICROLAB 600 instruments? Note: Call Microlab Technologies Technical/Customer Service Department if you have questions about maintaining your MICROLAB 600 system. How can I determine the accuracy for my Hamilton MICROLAB 600? Hamilton has developed a gravimetric method for determining the accuracy of our MICROLAB 600. Click here for the procedure [Back to Top] What can I do if I am getting corrosion and crystallization in my syringe(s) and valve(s) from my saline/salt based solutions? Salts, including saline are as rough or rougher on the MICROLAB 600's than concentrated acids. Make sure to flush the system thoroughly when you are finished using the instrument. Remove the syringes, valve, and tubing so the components can air dry. [Back to Top] How tight should fittings on the valve be? The fittings should only be finger tight or 13 ounce inches. Over tightening the fitting will cause the valve to rotate, rub the fitting, and ultimately cause the valve to fail. This is a leading cause of premature valve failures. [Back to Top] When will the valve need to be replaced? The MICROLAB valves may last for several years depending on use. Eventually they need to be replaced from normal wear and tear. Below are common signs the valve needs to be replaced:
My MICROLAB 600 is making strange noises, what should I do? When a MICROLAB 600 starts to make noise, it needs to be serviced. A squealing sound indicates a lack of lubrication on the lead screw. A grinding sound indicates a bearing has failed. Please call the Microlab Technologies Service Department to discuss your service options [Back to Top] How often should I calibrate my MICROLAB 600? Every user has different applications and requirements for calibration, but a general rule, calibrate the instrument on the same interval used for analytical balances. (Generally once or twice per year) [Back to Top] How do I clean and maintain my MICROLAB 600? Hamilton has outlined the cleaning and maintenance for the MICROLAB 600 in the Basic manual, Chapter 4. Click here for the details [Back to Top] What is the recommended preventative maintenance schedule for the MICROLAB 600 instruments? The maintenance schedule is determined by the frequency of use and the types of solvents being used.
