Top 6 Signs That You Should Service or Replace Your Analytical Balance

  1. The balance is unable to hold calibration, needing re-calibration after very few weighing tasks.
  2. The displayed results drift up or down, jump for no apparent reason, or are consistently unstable.
  3. The lab’s weighing needs have changed and the facility could benefit from more advanced features such as up-todate data communication interfaces, statistical calculations, storage of readings, and product identification codes.
  4. The stability and repeatability are no longer accurate.
  5. Integration to a computer may be necessary and there may be definitive signs of corrosion.
  6. The balance requires constant maintenance.

Top 6 Questions You Should Ask When Buying a Lab Balance

  1. What is the heaviest sample you will weigh (including container weight) and what is the lightest sample?
  2. What is the required +/- tolerance of your lightest sample?
  3. How many decimal places in grams do you require for the displayed weight?
  4. What type of samples will you be weighing and do you need to take into consideration the size of the weighing surface or the securing of a tare container?
  5. Is on-site service available from a factory-trained service technician?
  6. Do you need to interface the balance to another device such as a computer, printer, bar code reader, etc.?

Coolant Vapor buildup
I have been using a MSX250A saw and have noticed that after I am done cutting and lift up the cover, there is a release of vapors that I believe to be from the coolant I am using.  I was wondering if there is any kind of method to ventilate the machine that could remove the vapors before I have to open the cover so that I do not have to be exposed to the vapors (It is in a small room with minimul ventilation already).  Thanks for any suggestions!  Respond to this question.
