Germany Cohen PBS420-3M precision balance is an electronic balance with multi-function advanced cutting-edge sensor system, built-in high-precision load cell, so its accuracy and sensitivity have been improved, and it is widely used in the laboratory, research and other places. Analytical work. PBS420-3M standard windshield design, the top removable cover is easy to use pipette operation, weighing space size DxH184X230X90mm, only for models with readability d=0,001g. So we need to pay attention to some details when using, so that we can improve its weighing accuracy.

Germany Cohen PBS420-3M precision balance use notes:

1. Full preheating before use, generally should be more than 30 minutes. The higher the accuracy of the balance, the longer the preheating time should be.

2. Before use, use the standard weight to correct the weight of the corresponding grade selected by the balance of different accuracy.

3. The time reading should be fixed after loading, such as reading with the indication value of 5 seconds after loading or reading the value when the unit is displayed.

4, multiple measurements, take the average (3 ~ 5 times).

5, the room should avoid direct sunlight, choose a shady room or use shading.

6. The precision balance should be away from the source, such as railways, highways, vibration machines and other vibration machinery. When it is unavoidable, anti-seismic measures should be taken.

7. Keep away from heat sources and high-energy electromagnetic fields.

8. The temperature in the working room should be constant, preferably around 20 °C.

9. The relative humidity in the working room should be between 45% and 75%.

10. The workroom should be clean and clean to avoid the influence of airflow.

11. Adjust the level bubble to the middle position before use.

Chromatography Resins & Pre-packed Columns

Nanomicro Tech produces the most complete range of monodisperse chromatographic media and SPE sorbents based on acrylic polymers, polystyrene or silica . The spherical and monodisperse sorbents with precisely controlled uniform particle size, optimized pore structure and surface functionalization provide high resolution , excellent selectivity , low back pressure , high recovery yield , and exceptional batch-to-batch reproducibility. Nanomicro Tech is one of the few companies having capability to manufacture both polymeric and silica based chromatography media for reversed phase, normal phase, ion exchange, hydrophobic interaction, affinity and Protein A affinity chromatographic separations. Both monodisperse non-porous and porous (100 Å, 300 Å, 500 Å, 1000 Å) media with a size selection as small as 1.7µm for UPLC, and as large as 100µm for process-scale chromatography, are available from Nanomico Tech
