Top 5 Questions You Should Ask When Buying a Centrifuge

When it comes to common technology in a laboratory, centrifuges rise toward the top of the list. Centrifuges separate particles and structures suspended in liquid by applying thousands of gravitational force equivalents to the sample through spinning and play a role in a wide range of workflows and applications.

  1. What is the maximum g-force the centrifuge can generate?
  2. How does the company’s centrifuge differ from other ones that can achieve the same speed and capacity?
  3. What kind of warranty comes with the centrifuge and what does it cover?
  4. If the company discontinues the product, for how many years do they provide accessories and parts for the centrifuge?
  5. Ask about cost of the purchase— not just the price of the product being installed but the total cost of ownership including price, service expectations, warranty, etc.

Pharma Test PTWS 100D - Preventive maintenance
I need the preventive maintenance procedure for pharmatest PTWS 300/600/1200 dissolution apparatus. Advise this member.

Thermo IEC Centra CL3R
I have the above centrifuge. Does anyone know where the access port is for the emergency cord to use in the event the power fails and samples must be removed? There is no access port under the front ledge as the manual states. There is a black plastic cover on the left side right behind the fuse port but I have not been able to get that off. Is that the port for the emergency cord? If so, is there a trick in getting is off? Advise this member.

Sorvall RC-6 - Alarm "ROTOR NO."
My sorvall RC-6 centrifuge gives alarm message "ROTOR NO." above 3200 rpm, although the rotor number (SLA 1500) and its code (28) are entered correctly. Below 3200 rpm it works properly. What is this problem? How can it be fixed? Advise this member.
