Centrifuges are one of the most frequently used instruments in scientific and diagnostic laboratories around the world. They can also be a source of noise pollution. Standard devices for up to 24 tubes of 1.5 or 2.0 mL are an integral component of many workflows including DNA/RNA extraction and protein purification. These centrifuges are continually in use and often sit on the laboratory bench right next to the users. State-of-the-art centrifuges specially designed for low noise operation help to reduce the overall noise level and contribute to a more enjoyable and productive working environment.
During the development of a 24-place Centrifuge special attention on low noise emission must be paid. Short centrifuge runs of up to 12 minutes should be whisper quiet, because most centrifugation runs are shorter. This length of time is sufficient for the centrifugation steps required by most DNA/RNA extraction kits, demanding often only 30 seconds or 2 minutes. The average noise level of 45 dB(A) should not be exceeded during these short runs. Only during longer runs the ventilator will switch to full capacity to dissipate heat from the instrument – but even then, the modern centrifuges can remain quiet with a noise level below 51 dB(A).
