Weigh the Right Way with Excellence Weighing Solutions
Weighing is often the first step in many analytical procedures, and any error in your weight measurement can therefore negatively impact your entire analysis.
Proper weighing means following procedures and guidelines for the correct selection, installation, and operation of your balance to minimize the uncertainty in your results.
Potential Weighing Challenges
Problem, Air Drafts: Drafts can cause drifting and affect accuracy. Common sources of air drafts in the lab include safety cabinets and fume hoods, doors and windows opening and closing, biohazard cabinets, and AC units.
Solution: Smart weighing pans from METTLER TOLEDO allow you to weigh without a draft shield, and are available for XPR/XSR precision and analytical balances.
Problem, User Skill: Users have different techniques and skill levels in sample handling and balance operation and knowledge of following and interpreting weighing SOPs.
Solution: METTLER TOLEDO not only provides the proper tools for the job, we also offer extensive training and support from industry experts. LabX for standardization of workflows, traceability, and data management/integrity is also key to user success.
Problem, Vibrations: The smaller the readability, the more susceptible a balance is to external vibration. Common sources of vibration in the lab include other equipment and instrumentation, foot traffic, etc.
Solution: Choosing a location with minimal vibration is key and, ideally, the bench should not be fastened to the wall. Instead, use a dedicated weighing table like a marble table/slab or balance table from METTLER TOLEDO.
Problem, Electrostatic Charges: The main hidden source of weighing error, electrostatic charges are generated by friction when drying a glass beaker, using disposable gloves and plastic, and filling a tare vessel.
Solution: XPR analytical balances can detect and eliminate electrostatic charges on a sample and container. StaticDetect identifies charges, which are eliminated by the integrated ionizing module. Legacy model and external options are also available.
