VWR B2 Series Analytical and Precision Laboratory Balances (Models 124B2 & 5002B2)

The VWR B2 Series includes two laboratory balances optimized for diverse weighing applications, featuring models 124B2 and 5002B2:

• VWR 124B2 Analytical Balance: Designed for milligram precision with a 0.0001 g readability and a maximum capacity of 120 g. It features a full glass draft shield that minimizes airflow disturbance, ensuring stable and quick stabilization within 2 seconds. The 100 mm diameter weighing platform supports routine analytical measurements critical for molecular diagnostics and bioprocessing workflows.

• VWR 5002B2 Precision Balance: Suitable for larger sample sizes requiring up to 5000 g capacity with 0.01 g readability. Equipped with a 190 x 190 mm pan, this model stabilizes in 1.5 seconds, ideal for bulk reagent weighing and general laboratory workflows in biomanufacturing and clinical diagnostics.

Both models support multiple weighing modes including grams (g), milligrams (mg), kilograms (kg), percentage weighing (% weigh), and parts counting, enhancing versatility for synthetic biology research and quality control protocols. The balances operate using a user-friendly menu system with adjustable environmental filtering, adapting to lab conditions between 10°-40°C.

Connectivity is facilitated via RS-232 interface, enabling direct data capture for laboratory information management systems (LIMS), supporting efficient biotechnological data documentation and analysis.

Key technical specifications:

• Repeatability: 0.0001 g (124B2), 0.01 g (5002B2)
• Linearity: ±0.2 mg (124B2), ±0.02 g (5002B2)
• Dimensions: 8 x 12 x 11 in (124B2), 8 x 14 x 4 in (5002B2)
• Power: 100-240 VAC, 50/60 Hz

The VWR B2 Series balances are essential for laboratories requiring reliable, high-accuracy weighing solutions that support a broad range of biotechnology applications including gene editing, synthetic biology, and biopharmaceutical production pipelines. Their bench-friendly footprint and simplified operation make them popular among molecular biology researchers and quality control professionals aiming for consistent and precise measurement outcomes.
