Question 1

What is an orbital shaker and in which applications is it used?

Accepted Answer

An orbital shaker mixes samples with high reproducibility through a circular orbital motion. Widely used for bacterial and yeast culture, protein expression optimization, solubility and extraction testing, ELISA incubation, and staining procedures. It is a core instrument in microbiology, biochemistry, genomics, and pharmaceutical research laboratories.

Question 2

What are the technical specifications of the orbital shaker?

Accepted Answer

The YEKLAB orbital shaker operates at 20-250 rpm with a 3 mm orbital diameter; maximum load capacity is 5 kg. Digital speed and timer controls support continuous and timed operation modes. Platform size options are 35×35 and 45×45 cm; a stainless steel platform and body provide corrosion resistance.

Question 3

Which platforms and adapters can be used with the orbital shaker?

Accepted Answer

Available adapters include Erlenmeyer flask clamps (25 mL-2000 mL), microplate holders (96/384-well), petri dish adapters, Falcon tube rack adapters, and glass bottle holders. Selecting the appropriate adapter optimizes mixing homogeneity and maintains sample integrity.

Question 4

How is the correct speed and duration determined?

Accepted Answer

Recommended speeds: 150-250 rpm for E. coli culture; 200-300 rpm for yeast; 50-100 rpm for sensitive protein refolding; 100-150 rpm for ELISA washing. On first use, the optimal speed should be confirmed via turbidity measurement or visual observation. Higher speeds may cause foaming and aerosol risk.

Question 5

How is the orbital shaker maintained?

Accepted Answer

Weekly: wipe the platform with 70% ethanol and clean adapters. Monthly: inspect vibration dampers under the motor. Annual: verify speed calibration with a tachometer; excessive vibration or noise indicates motor wear. YEKLAB provides replacement adapters and technical service support.

Question 6

When should an orbital shaker be upgraded to an incubating shaker model?

Accepted Answer

A standard orbital shaker is suitable for applications at fixed room temperature. For cell culture (37°C), protein expression optimization, or low-temperature enzymatic assays, an incubating shaker with heating or cooling capability should be preferred. The choice depends on the temperature sensitivity and protocol requirements of the application.
