Accuracy is the backbone of every pharmaceutical lab, calibration facility, and industrial quality control unit. A Standard Weight Box 1mg to 200g (23 Pieces) is not just a tool but a complete calibration solution designed for precision and compliance.

But why does this weight box have exactly 23 pieces? Why do some weights come in duplicate? And why is it important to buy from a certified manufacturer like V-CARE IMPEX?

This guide will give you all the answers.

Understanding the Shapes of Milligram Weights

Since milligram weights are extremely small, they are manufactured in different shapes for easy identification:

Triangle Shape → 1mg, 10mg, 100mg
Square Shape → 2mg, 20mg, 200mg
Hexagon/Pentagon Shape → 5mg, 50mg, 500mg

👉 These shapes reduce human error and make handling with tweezers simple and accurate.

Tip: Always keep mg weights dust-free and handle them gently to preserve accuracy.

Why Do Standard Weight Boxes Have Duplicate Rider Weights?

In every 1mg to 200g weight box, some values appear in duplicates:

2mg → 2 pieces
20mg → 2 pieces
200mg → 2 pieces

These are called rider weights, and their purpose is:

Flexibility – More possible weight combinations.
Calibration accuracy – Perfect for fine adjustments.
Error reduction – Eliminates reliance on a single piece.

This ensures smooth, error-free calibration for sensitive balances.

For example, to achieve 40mg, you can use either two × 20mg or a mix of 10mg + 30mg (by combining smaller weights). This flexibility ensures smooth calibration.

The Complete 23-Nos. Standard Weight Box (1mg to 200g)

A standard set includes both wire-type mg weights and knob-type gram weights:

Milligram Weights (Wire Type):1mg, 2mg × 2, 5mg, 10mg, 20mg × 2, 50mg, 100mg, 200mg × 2, 500mg

Gram Weights (Knob Type):1g, 2g × 2, 5g, 10g, 20g × 2, 50g, 100g, 200g

✔ Total = 23 Pieces covering all values from 1mg to 200g.

Role of OIML R111 Standards in Standard Weight Boxes

The OIML R111 Standard defines the global benchmark for standard weights. It covers:

Tolerance levels – Maximum permissible error
Material selection – Stainless steel, anti-magnetic
Design requirements – Shapes, edges, and finish
Classification – E1, E2, F1, F2, M1 classes

👉 Compliance with OIML R111 ensures your weight box is globally accepted, pharma audit ready, and calibration certified.
