A&D BM-22 Ion Microbalance, Dual Range 5.1 g x 0.001 mg / 22 g x 0.01 mg, Internal Calibration

Description

A&D BM-22 Ion Microbalance: 5.1 g × 0.001 mg / 22 g × 0.01 mg

The A&D Weighing BM-22 is a dual-range microbalance from A&D’s Ion BM series. Its fine range reads 0.001 mg (1 µg) up to 5.1 g, and its standard range reads 0.01 mg up to 22 g. A&D’s enhanced OES (Ordinal Electromagnetic Sensor) delivers microgram resolution, and a built-in fan-less ionizer removes static charge from samples and vessels at the press of the ION key.

One-touch internal calibration and Automatic Self Calibration keep the balance accurate as the room temperature changes. Built-in sensors display temperature, humidity, and atmospheric pressure; anti-static coated glass and a large weighing chamber block outside interference; and USB and RS-232C come standard for GLP/GMP/ISO data output.

Key Features

• Dual range: 5.1 g × 0.001 mg and 22 g × 0.01 mg
• Repeatability 0.004 mg (1 g load) / 0.01 mg; linearity ±0.010 mg / ±0.02 mg
• Built-in fan-less ionizer with one-touch ION key
• Internal calibration (one-touch) and Automatic Self Calibration for temperature changes
• Environmental sensors for temperature, humidity, and pressure
• Anti-static glass breeze chamber with a large weighing space
• Auto response adjustment for drafts and vibration
• Illuminated level bubble
• USB and RS-232C standard; GLP/GMP/GCP/ISO reports; data memory up to 200 points

Applications

Pharmaceutical and Analytical Labs

Weigh reference standards, small API samples, and trace quantities to the microgram.

Filter and Particulate Weighing

The ionizer and anti-static chamber help with filters and powders that pick up static.

Research and Materials Science

Use the 22 g range for vessels and the 5.1 g range for microgram readings in the same instrument.

Calibration Options from MNM Scales

Get your BM-22 calibrated and ready to use on day one. Add either option to your order, and our TDA-registered technicians calibrate it in-house before it ships:

• In-house calibration with certificate, using NIST-tested weights: $95. We calibrate and verify your BM-22 with NIST-tested weights and include a calibration certificate, so it arrives set up and accurate. Add $95 calibration to cart
• NIST calibration with a NIST-traceable certificate: $395. Full calibration documented on a NIST-traceable certificate, for pharmaceutical labs, QC programs, and audits that need a paper trail. Add $395 NIST calibration to cart

We also recalibrate scales and balances you already own, by mail-in or in our shop, with on-site service across Houston and the surrounding area. Request calibration or call (832) 290-3120.

Frequently Asked Questions

What is the readability of the A&D BM-22?

0.001 mg (1 µg) up to 5.1 g and 0.01 mg up to 22 g.

Does the BM-22 have internal calibration?

Yes. It has one-touch internal calibration and Automatic Self Calibration, plus external calibration if you need it.

Does the BM-22 remove static?

Yes. A built-in fan-less ionizer neutralizes charged samples and vessels, and the glass breeze chamber is anti-static coated.

Is the AD-1688 data logger included?

No. USB and RS-232C are built in; the AD-1688 logger is an optional accessory.
