Recently Asked Questions

Sorvall/RC-5B - Rotor overheating
Recently, one of our Sorvall RC-5B users did a 2-hour run at 15k RPMs that resulted in the GSA rotor getting so hot the plastic sample bottles melted. (The load was balanced, refrigeration was not used.) The next day I did a 1-hour run at 5,000 RPMs with an empty SS-34 rotor. It was slightly warm. The motor and spindle assembly wasn't hot, so I'm ruling out bad bearings. I've never seen this before. Did they simply run it too fast for too long? Any insights would be appreciated, Advise this member.

Milton Roy/Spectronic 20D+ - QA Coordinator
I have a Milton Roy Spectronic 20D and I was wondering how often do I need to replace the lamp? Is it after a certain amount of hours of use? Advise this member.

Sorvall/RC-5B - Rotor detachment
We have twice now had an aluminium SS34 rotor come detached from the spindle during the increase to speed and it writes off the rotor. Both times the user was certain they put it on correctly and they have all been trained. I wondered if anyone else has experienced this? Advise this member.

Sonicators: How these agitating lab instruments work

Energy comes in many forms. One of those is sound energy, which manifests as vibration. For example, we can hear a loud noise because receptor cells in our ears translate vibrations from sound energy into brain-bound electrical signals. Most sound waves lie outside our range of “hearing,” but produce energy nonetheless. In labs, this ultrasonic energy is used to agitate particles for the purpose of cleaning, mixing solutions, increasing dissolution rate, or to evaporate dissolved gasses from liquids.

Lab Equipment Questions for the Experts

Siemens Water Technologies/Ultra Clear RO/EDI - Prefiltration and conditioning modules
What is the life of the pretreatment and conditioning modules? We use the unit in an educational setting, so we can run through a couple tanks one day and then not need more for a week or longer. The sales rep recommended 3-4 months for pretreatment and 6 months for conditioning, but how many hours are they assuming are used each month? Advise this member.

Thermo Scientific/Avatar 360 FTIR - Newer Windows install
I have installed the Thermo Nicolet FT-IR 360 on a new system (Windows 7, 32 bit). The software has installed correctly, and I have performed all the necessary start up procedures according to the Install Wizard. However, the software still does not recognize the machine. Both the power and scan lights are active and lighting up. The software is OMNIC version 6.2. Looking for any information that could solve this problem. Advise this member.

Beckman Coulter/DTX 800/880 Series - Error code 21
I have an error code of Device code 21: Brightness below detection limits. What do I need to change to fix this? Advise this member.
