About BENCHMARK SCIENTIFIC

Benchmark Scientific is a manufacturer of benchtop laboratory equipment, with a product portfolio that includes centrifuges, shakers, vortex mixers, dry baths, and related accessories. The company was founded in the United States and has since established a global presence, serving research institutions, clinical laboratories, and industrial quality-control facilities. Its equipment is designed for routine sample preparation, mixing, and separation tasks, with an emphasis on compact footprints, simple operation, and compatibility with standard labware. 3G Electric, a Singapore-headquartered industrial-equipment distributor, supplies Benchmark Scientific products to customers worldwide, offering access to the full line of benchtop instruments and replacement parts.

The Benchmark Scientific product range covers several core categories. Centrifuges include mini-centrifuges for microtubes and PCR strips, as well as fixed-angle rotors for microcentrifuges. These instruments are used for pelleting cells, precipitating nucleic acids, and quick spin-downs. Shakers and rockers provide gentle to vigorous agitation for cell cultures, blots, and staining procedures. Vortex mixers are available in single-tube and multi-tube formats for resuspending pellets and mixing reagents. Dry baths and block heaters offer precise temperature control for enzyme reactions, incubation, and sample preparation. Lab rollers, such as the R3010 and R3005 models, deliver gentle rolling and tilting action for blood tubes and biological samples, with speed ranges from 2 to 80 RPM and a 5° tilt. Accessories include interchangeable rotors, tube adapters, and replacement parts to extend instrument life.

Technical buyers will find that Benchmark Scientific equipment is built to standard laboratory requirements. Many models feature digital displays, programmable operation, and variable speed control. Voltage options often span 100 to 240V, accommodating different regional power standards. Mini-centrifuges are available with fixed or variable speed, and capacities range from 8 x 1.5/2 mL tubes to 48 x 0.2 mL tubes or 4 x 12-position PCR strips. Rotors are designed for specific tube sizes and applications, such as the C2417-3202 fixed-angle rotor for 32 x 1.2 mL tubes, achieving a maximum relative centrifugal force of 13,602 x g. Lab rollers accommodate up to 18 x 50 mL tubes or 8 x 125 mm tubes, with smooth tilting for gentle mixing. These specifications make the equipment suitable for molecular biology, clinical diagnostics, and general laboratory workflows.

3G Electric supports the Benchmark Scientific line by maintaining inventory of popular models and accessories, providing technical specifications, and facilitating global shipping. The distributor serves plant engineers, maintenance managers, and procurement specialists who require reliable benchtop equipment for laboratory and quality-control operations. With a focus on clear documentation and responsive service, 3G Electric helps customers select the appropriate model for their application, whether it is a basic mini-centrifuge for quick spins or a programmable roller for extended mixing. The product range is complemented by a selection of replacement parts, ensuring that instruments remain operational over time. For detailed inquiries, 3G Electric can provide quotes and lead times based on current stock and shipping destinations.

Frequently asked questions

Common questions about BENCHMARK SCIENTIFIC from 3G Electric.

What is the maximum relative centrifugal force of the Benchmark Scientific C2417-3202 fixed-angle rotor?

The Benchmark Scientific C2417-3202 fixed-angle rotor achieves a maximum relative centrifugal force of 13,602 x g. It is designed for microcentrifuges and accommodates 32 x 1.2 mL tubes. The rotor has an overall diameter of 2 3/4 inches. This rotor is suitable for pelleting cells, precipitating nucleic acids, and other small-volume separations requiring high g-force. It is a direct replacement or additional rotor for compatible Benchmark Scientific microcentrifuges. When selecting this rotor, verify that your centrifuge model supports the rotor's mounting mechanism and maximum speed rating.

What are the speed and capacity specifications of the Benchmark Scientific R3010 lab roller?

The Benchmark Scientific R3010 lab roller operates at speeds from 2 RPM to 80 RPM, with a minimum speed of 2 RPM. It provides a smooth 5° tilting action and accommodates up to 18 x 50 mL tubes. This roller is intended for gentle mixing of biological samples, cell cultures, and blood tubes. The variable speed range allows for adjustment based on sample sensitivity and mixing requirements. The R3010 uses a standard plug style and is designed for benchtop use. It is part of the Benchmark Scientific line of lab rollers, which also includes models with different tube capacities.

Can the Benchmark Scientific C2248 mini-centrifuge accommodate PCR strips?

Yes, the Benchmark Scientific C2248 mini-centrifuge is designed to accommodate 4 x 12-position PCR strips, equivalent to 48 x 0.2 mL tubes. It features a digital display, variable speed control, and programmable operation. The unit operates on 100 to 240V, making it suitable for use in different regions. This mini-centrifuge is used for quick spin-downs of PCR strips and microtubes, helping to collect contents at the bottom of wells before thermal cycling or analysis. The angled rotor design facilitates efficient separation. For specific protocols, refer to the instrument manual for compatible tube types and maximum speeds.

What is the difference between the Benchmark Scientific C2212 and C2248 mini-centrifuges?

The Benchmark Scientific C2212 and C2248 mini-centrifuges differ primarily in capacity and rotor type. The C2212 accommodates 12 x 1.5 or 2 mL tubes or 32 x 0.2 mL tubes, while the C2248 accommodates 48 x 0.2 mL tubes or 4 x 12-position PCR strips. Both models feature a digital display, programmable operation, and operate on 100 to 240V. The C2212 uses an angled rotor for 1.5/2 mL tubes, whereas the C2248 has an angled rotor designed for PCR strips. The choice between them depends on the tube format and throughput required for your application.

Does the Benchmark Scientific BSC1006-B mini-centrifuge have variable speed control?

No, the Benchmark Scientific BSC1006-B mini-centrifuge operates at a fixed speed. It is a benchtop model designed for basic centrifugation of micro tubes and 2 x 8 place PCR strips. It operates on 115V AC and does not include a display or programmable settings. This model is suited for quick spin-downs where a single speed is sufficient. For applications requiring variable speed or programmability, consider other Benchmark Scientific mini-centrifuges such as the C2212 or C2248. The BSC1006-B is a straightforward option for routine microtube centrifugation.

What tube sizes are compatible with the Benchmark Scientific R3005 lab roller?

The Benchmark Scientific R3005 lab roller is designed for 8 x 125 mm tubes. It operates at speeds from 2 RPM to 80 RPM with a smooth 5° tilting action, providing gentle rolling and tilting mixing. This model is suitable for blending samples in tubes up to 125 mm in length. The R3005 is part of the Benchmark Scientific lab roller family, which includes models with different capacities, such as the R3010 for 50 mL tubes. Both models share similar speed ranges and tilting action, but differ in tube compatibility. Verify tube dimensions and material compatibility before use.
