Safety Information for the SW 32 Ti and SW 32.1 Ti Rotors
Handle body fluids with care because they can transmit disease. No known test offers complete assurance that such fluids are free of micro-organisms. Some of the most virulent —Hepatitis (B and C) viruses, HIV (I–V), atypical mycobacteria, and certain systemic fungi—further emphasize the need for aerosol protection. Handle other infectious samples according to good laboratory

procedures and methods to prevent spread of disease. Because spills may generate aerosols, observe proper safety precautions for aerosol containment. Do not run toxic, pathogenic, or radioactive materials in these rotors without taking appropriate safety precautions. Biosafe containment should be used when Risk Group II materials (as identified in the World Health Organization Laboratory Biosafety Manual) are handled; materials of a higher group require more than one level of protection.
The rotors and accessories are not designed for use with materials capable of developing flammable or explosive vapors. Do not centrifuge such materials in nor handle or store them near the centrifuge
Although rotor components and accessories made by other manufacturers may fit in the SW 32 Ti and SW 32.1 Ti rotors, their safety in these rotors cannot be ascertained by Beckman Coulter. Use of other manufacturers’ components or accessories in these rotors may void the rotor warranty and should be prohibited by your laboratory safety officer. Only the components and accessories listed in this publication should be used in this rotor.
Attach all six buckets, loaded or empty, to the rotor for every run. Make sure that filled containers are loaded symmetrically into the rotor and that opposing tubes are filled to the same level with liquid of the same density. Make sure that buckets containing Quick-Seal tubes have the proper floating spacers inserted (if applicable) before installing the bucket cap.
If disassembly reveals evidence of leakage, you should assume that some fluid escaped the rotor. Apply appropriate decontamination procedures to the centrifuge and accessories.
Never exceed the maximum rated speed of the rotor and labware in use. Refer to the section on Run
Speeds, and derate the run speed as appropriate.
Do not use sharp tools on the rotor that could cause scratches in the rotor surface. Corrosion begins in scratches and may open fissures in the rotor with continued use.

2. O-ring (812715)
3. Bucket (SW 32 Ti)
4. Rotor
5. Overspeed Disk (335456)
These Beckman Coulter rotors have been manufactured in an ISO 9001 or 13485 facility for use with the specified Beckman Coulter ultracentrifuges.
The SW 32 Ti and SW 32.1 Ti are swinging bucket rotors designed to centrifuge up to six tubes each. Used in Beckman Coulter class H, R, and S preparative ultracentrifuges, these rotors develop centrifugal forces for the separation of subcellular particles and viruses in density gradients. The rotors have a common rotor body with buckets that can be used interchangeably (see
Rotor
Preparation). Bucket and rotor body positions are numbered for operator convenience.
The rotor body and buckets are made of titanium, finished with polyurethane paint. Bucket caps are made of aluminum, anodized for corrosion resistance. Each bucket and cap assembly sets into grooves in the rotor body. O-rings, made of Buna N rubber, between each bucket and bucket cap maintain atmospheric pressure inside the buckets during centrifugation.
For overspeed protection, a Beckman Coulter ultracentrifuge equipped with a photoelectric detector will monitor the overspeed disk on the rotor bottom and shut down the run if a speed exceeding the maximum allowable run speed is detected.
See the Warranty at the back of this manual for warranty information.

Make sure that the rotor is equipped with the correct overspeed disk.
a. If the disk is missing or damaged, replace it according to the instructions in Rotors
and Tubes
.
3
Verify that the tubes and bottles being used are listed in Table 1 or Table 2.
4
Check the chemical compatibilities of all materials used.
Refer to Chemical Resistances (publication IN-175), included in the Rotors and Tubes CD.
Rotor Preparation
For runs at other than room temperature refrigerate or warm the rotor beforehand for fast equilibration.
NOTE
4

5
Grasp the bucket cap tabs and lower the buckets into the openings on the rotor body with the rounded sides toward the outside of the rotor.
Operation
NOTE
Six bucket assemblies must be installed, whether loaded or empty. If fewer than six tubes are being run, they must be arranged symmetrically in the rotor (see Figure 1). Opposing tubes must be filled to the same level with liquid of the same density.
Figure 1 Arranging Tubes Symmetrically in the Rotor Buckets
NOTE Two, three, four, or six tubes can be centrifuged per run if they are arranged in the rotor as shown. All
bucket assemblies must be attached to the rotor, whether loaded or empty.
A bucket will not seat in the rotor if it is inserted in the rotor with the rounded side toward the rotor
center. The bucket will fall through, spilling or disturbing the tube contents.
For low-temperature runs, precool the rotor in the centrifuge or in a refrigerator before use—especially before short runs—to ensure that the rotor reaches the set temperature. A suggested precooling cycle is a minimum of 30 minutes at 2000 RPM at the required temperature.
1
Refer to the centrifuge instruction manual for additional operating instructions.
2
For additional operating information, see the following:
Run Times, page 12, for using k factors to adjust run durations.
Run Speeds, page 13, for information about speed limitations.

CAUTION
If disassembly reveals evidence of leakage, you should assume that some fluid escaped the rotor. Apply appropriate decontamination procedures to the centrifuge and accessories.
1
Grasp the bucket cap tabs and lift up to remove the buckets.
(Buckets may be removed without removing the rotor body from the ultracentrifuge.)
2
Remove the bucket caps by twisting counterclockwise and lifting up.
a. Use a tube removal tool (361668) or hemostat to remove the spacers and tubes.

Temperature Limits
Plastic tubes have been centrifuge tested for use at temperatures between 4 and 25°C. For
centrifugation at other temperatures, pretest tubes under anticipated run conditions.
If plastic containers are frozen before use, make sure that they are thawed to at least 4°C prior to centrifugation.
OptiSeal Tubes
OptiSeal™ tubes come with plastic plugs and can be quickly and easily prepared for use. With the tube spacer in place, the g force during centrifugation ensures a tight, reliable seal that protects your samples.

Preparation and Use
1
Place the tubes in the rack and fill each tube to the base of the stem, leaving no fluid in the stem.
Overfilling the tube can cause spillage when the plug is inserted or can compromise seal integrity.
However, too much air can cause excessive tube deformation, disrupting gradients and sample bands.

Refer to Using OptiSeal™ Tubes (publication IN-189), included in each box of tubes, for detailed information on the use and care of OptiSeal tubes.
Quick Seal Tubes
Quick-Seal® tubes must be sealed prior to centrifugation. These tubes are heat sealed and do not need caps; however, spacers are required on top of the tubes when they are loaded into the rotor buckets.
1
Fill Quick-Seal tubes leaving a small bubble of air at the base of the neck.
a. Do not leave a large air space—too much air can cause excessive tube deformation.
2
Some of the tubes listed in Table 1 and Table 2 are part of the g-Max™ system, which uses a combination of small bell-top Quick-Seal tubes and floating spacers (also called g-Max spacers).
This means that you can run the shorter tubes listed in the Tables in the SW 32 Ti and SW 32.1 T rotors without reduction in g force.
For detailed information on the g-Max system see publication DS-709.

Quick-Seal tubes are disposable and should be discarded after a single use.
konical™ Tubes
Polyallomer konical tubes, used to optimize pelleting separations, have a conical tip that concentrates the pellet in the narrow end of the tube. The narrow bottom also reduces the tube’s nominal volume and minimizes gradient material requirement. The konical tubes come in both open-top and Quick-Seal tube designs. Conical cavity adapters hold the tubes in the rotor buckets
1. Adapters
Run Times
Polyallomer and Ultra-Clear Open-Top Tubes
Polyallomer and Ultra-Clear® open-top tubes should be filled as full as possible (2 or 3 mm from the tube top) for tube support. If necessary, float mineral oil (or some other low-density, immiscible liquid) on top of the tube contents to fill the tube to its maximum volume. (Do not use an oil overlay in Ultra-Clear tubes.) All opposing tubes for a run must be filled to the same level with liquid of the same density.
The k factor of the rotor is a measure of the rotor’s pelleting efficiency. (Beckman Coulter has calculated the k factors for all of its preparative rotors at maximum rated speed and using full tubes.) The k factor is calculated from the formula
EQ 1
where is the angular velocity of the rotor in radians per second (= 0.105 RPM), r maximum radius, and r
is the minimum radius.

Preparation and Use
Use the k factor in the following equation to estimate the run time t (in hours) required to pellet particles of known sedimentation coefficient s (in Svedberg units, S).
EQ 3
Run times can be estimated for centrifugation at less than maximum speed by adjusting the k factor as follows:
EQ 4
Run times can also be estimated from data established in prior experiments if the k factor of the previous rotor is known. For any two rotors, a and b:
EQ 5
where the k factors have been adjusted for the actual run speed used.
Run Speeds
The centrifugal force at a given radius in a rotor is a function of speed. Comparisons of forces between different rotors are made by comparing the rotors’ relative centrifugal fields (RCF). When rotational speed is selected so that identical samples are subjected to the same RCF in two different rotors, the samples are subjected to the same force. The RCF at a number of rotor speeds is provided in Table 3.
Do not select rotational speeds in excess of 32,000 RPM. In addition, speeds must be reduced under the following circumstances:
1. If nonprecipitating solutions more dense than 1.2 g/mL are centrifuged, reduce the maximum
2. Further speed limits must be imposed when CsCl or other self-forming-gradient salts are
allowable run speed according to the following equation:
EQ 6
where is he density of the tube contents. This speed reduction will protect the rotor from excessive stresses due to the added tube load.
centrifuged, as equation (6) does not predict concentration limits/speeds that are required to prevent precipitation of salt crystals. Solid CsCl has a density of 4 g/mL, and if precipitated during centrifugation may cause rotor failure. Figure 2 through Figure 5, together with the description and examples below, show how to reduce run speeds when using CsCl gradients.

Selecting CsCl Gradients
Rotor speed is used to control the slope of a CsCl density gradient, and must be limited to prevent CsCl precipitation during centrifugation. Speed and density combinations that intersect on or below the curves in Figure 2 (for the SW 32 T i rotor) a nd in Figure 4 (for the SW 32.1 Ti rotor) ensure that CsCl will not precipitate during centrifugation in these rotors. Curves are provided at two temperatures: 20°C (black curves) and 4°C (gray curves). Curves in Figure 2 through Figure 5 are provided up to the maximum speed of the rotor.
SW 32 Ti and SW 32.1 Ti Swinging-Bucket Rotors
Preparation and Use
NOTE
The curves in Figure 2 through Figu re 5 are for solutions of CsCl salt dissolved in distilled water only. If other salts are present in significant concentrations, the overall CsCl concentration may need to be reduced.
The reference curves shown in Figure 3 and Figure 5 show gradient distribution at equilibrium. Each curve inFigure 3 is within the density limits allowed for the SW 32 Ti rotor; each curve in
Figure 5 is within the density limits allowed for the SW 32.1 Ti rotor. Each curve was generated for
a single run speed using the maximum allowable homogeneous CsCl densities (one for each fill level) that avoid precipitation at that speed. (The gradients in Figure 3 and Figure 5 can be generated from step or linear gradients, or from homogeneous solutions. But the total amount of CsC l i n solut io n must b e e quivale nt to a homo ge neous solution corresponding to the concentrations specified in Figure 3 and Figure 5.) Figure 3 and Figure 5 can also be used to approximate the banding positions of sample particles. Curves not shown may be interpolated.
Adjusting Fill Volumes
Figure 2 through Figure 5 show that several fill volumes are possible in a tube. If a thinwall tube is
partially filled with gradient solution, float mineral oil (or some other low-density, immiscible liquid) on top of the tube contents to fill the tube to its maximum volume. (Do not use an oil overlay in Ultra-Clear tubes.) Note that for a given CsCl density, as the fill level decreases the maximum allowable speed increases. Partial filling may be desirable when there is little sample or when you wish to shorten the run time
For example, in the SW 32 Ti rotor, a quarter-filled tube of 1.69-g/mL homogeneous CsCl solution at 4°C may be centrifuged at 25,000 RPM (see Figure 2). The segment of the 25,000 RPM curve (Figure 3) from the quarter-filled line to r
a half-filled tube may be centrifuged no faster than 17,000 RPM, and 15,000 RPM in a three-quarter- filled tube. A tube full of the 1.69-g/mL CsCl solution may be centrifuged no faster than 13,500 RPM. Curves not shown in the figures may be interpolated

Typical Examples for Determining CsCl Run Parameters
Example A:
Starting with a homogeneous CsCl solution density of 1.40 g/mL and approximate particle buoyant densities of 1.38 and 1.42 g/mL, at 20°C, where will particles band at equilibrium in the SW 32 Ti rotor?

2. At Rest in Rotor
3. At Rest Outside Rotor
4. Floating Components
5. Bands
6. Pelleted Material
7. Pathlength
1
In Figure 2, find the curve that corresponds to the required run temperature (20°C) and fill volume (three-quarters full).
The maximum allowable rotor speed is determined from the point where this curve intersects the homogeneous CsCl density (28,000 RPM).
2
In Figure 3, sketch a horizontal line corresponding to each particle’s buoyant density.
3
Mark the point in Figure 3 where each particle density intersects the curve corresponding to the selected run speed and temperature.
Particles will band at these locations across the tube diameter at equilibrium during centrifugation.
In this example, particles will band about 120 and 125 mm from the axis of rotation, about 5 mm of centerband-to-centerband separation.
To determine interband volume in milliliters, use the following equation:
EQ 7
where r is the tube radius in centimeters and h is the interband separation in centimeters
Example B:
Knowing particle buoyant densities (for example, 1.55 and 1.50 g/mL), how do you achieve good separation in the SW 32.1 Ti rotor?
1
In Figure 5, sketch in a horizontal line corresponding to each particle’s buoyant density.

Care and Maintenance
2
Select the curve at the desired temperature (20°C) and tube volume (full) that gives the best particle separation.
3
Note the run speed along the selected curve (20,000 RPM).
4
From Figure 2, select the maximum homogeneous CsCl density (in this case, 1.56 g/mL) that corresponds to the temperature and run speed established above.
These parameters will provide the particle-banding pattern selected in Step 2.
In this example, particles will band about 119.5 and 129 mm from the axis of rotation (about
9.5 mm apart).
Care and Maintenance
Maintenance
NOTE Do not use sharp tools on the rotor that could cause scratches in the rotor surface. Corrosion begins
in scratches and may open fissures in the rotor with continued use.
1
Frequently check the bucket O-rings for signs of wear.
a. Replace O-rings every 6 months, or whenever worn or damaged. b. Use the hooked removal tool (978354) to remove O-rings. c. Keep the O-rings lightly coated with silicone vacuum grease (335148).
2
Regularly inspect the rotor body, buckets, and caps for cracks, pitting, or heavy discoloration.
NOTE
Wear will become visible over time on the contact areas between buckets and rotor body. Such
wear will not affect rotor operation.

Care and Maintenance
3
Frequently lubricate the bucket and cap mating surfaces with a thin, even coat of Spinkote lubricant (306812).
4
Refer to Appendix A in Rotors and Tubes for the chemical resistances of rotor and accessory materials.
Your Beckman Coulter representative provides contact with the Field Rotor Inspection Program and the rotor repair center.
Cleaning
Wash the rotor and rotor components immediately if salts or other corrosive materials are used or if spillage has occurred. Do not allow corrosive materials to dry on the rotor.
Under normal use, wash the rotor frequently (at least weekly) to prevent buildup of residues.
1
Wash the rotor buckets, O-rings, and caps in a mild detergent, such as Beckman Solution 555™, that won’t damage the rotor.
a. Dilute the detergent 10 to 1 with water.
The Rotor Cleaning Kit contains two plastic-coated brushes and two quarts of Solution 555
(339555) for use with rotors and accessories.
2
Rinse the cleaned rotor and components with distilled water.
3
Air-dry the rotor and buckets upside down. Do not use acetone to dry the rotor.
4
Air-dry the rotor and lid upside down.
a. Do not use acetone to dry the rotor.
5
Clean metal threads frequently to prevent buildup of residues and ensure adequate closure.
a. Use a brush and concentrated Solution 555. b. Rinse and dry thoroughly, then lubricate lightly but evenly with Spinkote to coat all
threads.

Decontamination
If the rotor or other components are contaminated with toxic, radioactive, or pathogenic materials, follow appropriate decontamination procedures as outlined by your laboratory safety officer. Refer to Appendix A in Rotors and Tubes to select solutions that will not damage the rotor and accessory materials.
Sterilization and Disinfection
The rotor and all rotor components, except those made of Noryl, can be autoclaved at 121°C for
up to an hour. Remove the plugs from the rotor and place the rotor, plugs, and spacers in the autoclave upside down.
Ethanol (70%) those made of plastic. Bleach (sodium hypochlorite) may be used, but may cause discoloration of anodized surfaces. Use the minimum immersion time for each solution, per laboratory standards.
*
or hydrogen peroxide (6%) may be used on all rotor components, including
SW 32 Ti and SW 32.1 Ti Swinging-Bucket Rotors
Returning a Rotor
While Beckman Coulter has tested these methods and found that they do not damage the rotor or components, no guarantee of sterility or disinfection is expressed or implied. When sterilization or disinfection is a concern, consult your laboratory safety officer regarding proper methods to use.
Refer to publication IN-192 (included with each box of tubes) for tube sterilization and disinfection procedures. Quick-Seal, Ultra Clear, and thinwall open-top tubes are disposable and should be discarded
after a single use.
Storage
When it is not in use, store the rotor and buckets in a dry environment (not in the instrument). Remove the bucket caps to allow air circulation so that moisture will not collect in the buckets.
Returning a Rotor
Before returning a rotor or accessory for any reason, prior permission must be obtained from Beckman Coulter, Inc. This form may be obtained from your local Beckman Coulter sales office. The form, entitled Returned Material Authorization (RMA) for United States returns or Returned Goods Authorization (RGA) for international returns, should contain the following information:
rotor type and serial number,
history of use (approximate frequency of use),
reason for the return,
* Flammability hazard. Do not use in or near operating ultracentrifuges.

Warranty Conditions (as applicable)
1. This warranty is valid for the time periods indicated above from the date of shipment to the original Buyer by Beckman Coulter or an authorized Beckman Coulter representative.
2. This warranty extends only to the original Buyer and may not be assigned or extended to a third person without written consent of Beckman Coulter.
3. This warranty covers the Beckman Coulter Centrifuge Systems only (including but not limited to the centrifuge, rotor, and accessories) and Beckman Coulter shall not be liable for damage to or loss of the user’s sample, non-Beckman Coulter tubes, adapters, or other rotor contents.
4. This warranty is void if the Beckman Coulter Centrifuge System is determined by Beckman Coulter to have been operated or maintained in a manner contrary to the instructions in the operator’s manual(s) for the Beckman Coulter Centrifuge System components in use. This includes but is not limited to operator misuse, abuse, or negligence regarding indicated maintenance procedures, centrifuge and rotor classification requirements, proper speed reduction for the high density of certain fluids, tubes, and tube caps, speed reduction for precipitating gradient materials, and speed reduction for high-temperature operation.
5. Rotor bucket sets purchased concurrently with or subsequent to the purchase of a Swinging Bucket Rotor are warranted only for a term co-extensive with that of the rotor for which the bucket sets are purchased.
6. This warranty does not cover the failure of a Beckman Coulter rotor in a centrifuge not of Beckman Coulter manufacture, or if the rotor is used in a Beckman Coulter centrifuge that has been modified without the written permission of Beckman Coulter, or is used with carriers, buckets, belts, or other devices not of Beckman Coulter manufacture.
7. Rotor parts subject to wear, including but not limited to rotor O-rings, VTi, NVT™, TLV, MLN, and TLN rotor tube cavity plugs and gaskets, tubing, tools, optical overspeed disks, bearings, seals, and lubrication are excluded from this warranty and should be frequently inspected and replaced if they become worn or damaged.
8. Keeping a rotor log is not mandatory, but may be desirable for maintenance of good laboratory practices.
Repair and Replacement Policies
1. If a Beckman Coulter rotor is determined by Beckman Coulter to be defective, Beckman Coulter will
repair or replace it, subject to the Warranty Conditions. A replacement rotor will be warranted for the time remaining on the original rotor’s warranty.
2. If a Beckman Coulter centrifuge is damaged due to a failure of a rotor covered by this warranty, Beckman Coulter will supply free of charge (i) all centrifuge parts required for repair (except the drive unit, which will be replaced at the then current price less a credit determined by the total number of revolutions or

years completed, provided that such a unit was manufactured or rebuilt by Beckman Coulter), and (ii) if the centrifuge is currently covered by a Beckman Coulter warranty or Full Service Agreement, all labor necessary for repair of the centrifuge.
3. If a Beckman Coulter rotor covered by this warranty is damaged due to a malfunction of a Beckman Coulter ultracentrifuge covered by an Ultracentrifuge System Service Agreement, Beckman Coulter will repair or replace the rotor free of charge.
4. If a Beckman Coulter rotor covered by this warranty is damaged due to a failure of a Beckman Coulter tube, bottle, tube cap, spacer, or adapter, covered under the Conditions of this Warranty, Beckman Coulter will repair or replace the rotor and repair the instrument as per the conditions in policy point (2) above, and the replacement policy.
5. Damage to a Beckman Coulter rotor or instrument due to the failure or malfunction of a non-Beckman Coulter tube, bottle, tube cap, spacer, or adapter is not covered under this warranty, although Beckman Coulter will assist in seeking compensation under the manufacturer’s warranty.
