[RASMB] Spin Analytical

[Tom Laue]

Dear RASMBers-
    I am pleased to announce that Spin Analytical 
(www.spinanalytical.com) will be producing the analytical 
ultracentrifuge cells, centerpieces and other tools and components 
developed by CAMIS for the Beckman XLI ultracentrifuge and the Aviv 
AU-FDS fluorescence attachment.
    In addition to the SedVel60K 2-channel centerpiece, there is a new 
4-channel velocity centerpiece (also rated to 60,000 rpm) for use with 
the Beckman interference optics and Aviv AU-FDS fluorescence optics. 
There are specialty centerpieces for meniscus matching (using the 
Stafford design), synthetic boundary and band forming. Six-channel 
sedimentation equilibrium centerpieces also are available. All of these 
centerpieces are available in 12-mm and 3-mm thickness.
    Special low volume centerpieces are available for the Aviv AU-FDS 
fluorescence optical system for the XLI. The velocity centerpiece 
requires only 60 uL of sample, and the 6-channel equilibrium centerpiece 
requires only 10 uL. Spin Analytical will also work with you to build 
custom-designed centerpieces. For example, ultra-thin (0.1-1 mm) 
centerpieces are being developed for absorbance detection with very high 
concentration samples. Also, a six-channel sector-shaped equilibrium 
centerpiece is being developed.
    In addition to centerpieces, Spin Analytical also sells cell housing 
kits, cell housings, window holders (including 'slit' interference 
window holders that will improve the signal to noise 5-fold or more), 
and other cell components. There is a cell alignment tool to ensure 
accurate and reproducible alignment of cells in the rotor. This may be 
used with Spin Analytical cell housings right out of the box or, with 
some calibration, used with Beckman cell housings. Other items are being 
developed to help with AUC. This fall, the first automated cell washers 
will be available.
    Spin Analytical services include cell and centerpiece inspection, 
evaluation and refurbishing. We will be glad to talk with you about 
custom centerpieces and data acquisition software.

    Proceeds from this company go towards the development of the next 
generation of analytical ultracentrifuge.

Best wishes,
Tom Laue
