Brass Analytical Weight Set (1mg–100g)

Quick Answer: The Brass Analytical Weight Set (1mg-100g) is a graduated collection of brass calibration weights spanning milligram quantities up to a nominal 100 g, used with physical, chemical and analytical balances for mass comparison, balance calibration checks and educational weighing exercises. Users select one or more weights from the set to build up a known combined mass for comparison against a sample.

Description

This set gives a laboratory a single, organised collection of reference masses covering a wide span, from fine milligram weights used for fine-tuning and small-mass work up to a nominal 100 g weight for larger comparisons. In practice, weights are combined to build up any required nominal mass and placed on a balance pan alongside (or instead of) the sample being weighed, letting students and technicians compare, check or calibrate readings. Milligram-range weights are typically the most delicate in the set and are usually handled with tweezers or forceps rather than bare hands, since skin oils and moisture can alter their mass slightly over time and affect measurement accuracy. The set is well suited to physics and chemistry laboratories that need a dependable range of reference masses for practical mass-measurement teaching and routine balance checks.

Specifications

Care & Maintenance

• Handle small/milligram weights with tweezers or forceps, not fingers, to avoid transferring oils or moisture that can alter mass over time.
• Store the set in its case or box with each weight in its designated slot to prevent loss and reduce surface contact/wear.
• Keep the set away from moisture, dust and corrosive fumes to protect the brass surface.
• Avoid dropping or knocking weights together, as nicks or dents will change their true mass.
• Periodically check weights against a certified reference if the set is used for calibration-sensitive work.
• Clean gently with a soft, dry cloth only — avoid abrasive materials or solvents on the brass surface.

Frequently Asked Questions

What mass range does this weight set cover?
As stated in the product name, the set spans from 1 mg up to a nominal 100 g, giving a wide range of reference masses in one collection.

What are the weights made of?
The weights in this set are made of brass.

How many individual pieces are in the set?
The exact denomination sequence and piece count can vary by configuration. Please confirm the specific breakdown with our sales team.

Should I handle the small weights with my hands?
No, especially for milligram-range weights, using tweezers or forceps is recommended to avoid transferring oils or moisture that can affect their accuracy over time.

Can this set be used to calibrate a balance?
Yes, sets like this are commonly used for balance calibration checks and mass comparison, though for certified calibration work you should confirm the accuracy class of the weights with our sales team.

How should the set be stored between uses?
Store it in its case with each weight in its designated slot, away from moisture, dust and corrosive fumes.
