Biosys-Scientific Tech Talk: The nicest thing about the old Clay Adams Serofuge I & II is size. The design remained the same for decades. Everyone got use to it and when the BD Clay Adams Serofuge 2001 & 2001 came out the first complaint was the footprint. It occupied more counter space when space was at a premium. Having been in field service and sales for 30 years, I know how important it is to have an instrument that preforms day in and day out regardless of it size. Why the change? It was OSHA regulations that brought about the industry to incorporate safety into our devices. I remember when ever tabletop centrifuge and cellwasher (remember the Sorvall CW1) had no locking mechanism. As a result, the entire instrument had to go through design changes, even the CW1 was converted to the DuPont-Sorvall CW2 occupying more counter space. But, it wasn't just the door lock mechanism. The industry had to device a way to incorporate a "zero-speed" detect circuit. Yes, something to detect when the rotor or head comes to a complete stop for your safety. Not to mention timing, memory, speed-RCF conversions, etc. Ah, its no wonder why the housing got bigger while the rotor.head remain the same. In ALL of the Serofuges you have an option of a plastic 12pl head or aluminum head assembly. You could hold onto your old head assemblys and use it on the newer version BD Clay Adams Serofuge 2001 & 2002. So, when considering a New BD Serofuge call me, I love to talk the talk.

The CW2 Plus is nothing more than the IEC Centra W. All they did was change the logo. At one time, these instruments were sold directly by IEC until Thermo bought it out. They decided to call it the CW2 Plus which came from the good old days of Sorvall (CW-1 & CW2) cellwasher systems. Yes, its normal for the chamber to be wet. During the decant cycle the 12 pl tube carriers (rotor) are held in a negative position so as to drain each tube during centrifugation. This causes the saline along with cells to hit the side walls of the white liner and gravity does the rest. I can understand your concern especially if your a "X" Sorvall user. Sorvall uses a completely different drain system and the chamber is allows dry as long as you don't over fill the tubes. In either system, always check the volume going into the tubes. Whether using 10 or 12ml tube just make sure your approx., 3/8 inch from the top of the tube. This should wash off the proteins from your samples and you'll get good results. As a field service engineer, I have been working on these systems, centrifugation and lots more for 29 years. I am a "X" DuPont-Sorvall field engineer.

We would like to help you. Nelson

I saw that someone was looking for spring clips. I have em. I also have many parts for Sorval, MSE, and Beckman centrifuges. I havent posted them on my web site yet.
