Safety Notice
This safety notice summarizes information basic to the safe use of the equipment described in this
publication. The international symbol displayed above is a reminder to the user that all safety
instructions should be read and understood before operation or maintenance of this equipment is
attempted. When you see the symbol on other pages of this publication, pay special attention to the
specific safety information presented. Observance of safety precautions will also help to avoid
actions that could damage or adversely affect the performance of the rotor system.
Safety Notice
• This rotor is warranted for 7 years (see the warranty at the back of this publication). Beckman
Coulter recommends that you retire the rotor from use at the end of the 7-year warranty period
to prevent the possibility of a rotor mishap resulting from material fatigue.
• Handle body fluids with care because they can transmit disease. No known test offers complete
assurance that they are free of micro-organisms. Some of the most virulent—Hepatitis (B and C)
and HIV (I–V) viruses, 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 this rotor 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.
• Dispose of all waste solutions according to appropriate environmental health and safety
guidelines.
• The rotor and accessories are not designed for use with materials capable of developing
flammable or explosive vapors. Do not centrifuge such materials (such as chloroform or ethyl
alcohol) in or handle or store them near the centrifuge.
• If glass tubes break, remove the glass very carefully from the adapter, bucket, or cavity. If all
the glass particles are not contained in the bucket or cavity, be careful when examining or
cleaning the centrifuge gasket and chamber as glass particles may be embedded in their
surfaces.
• Inspect the rotor once a month, especially inside cavities, for rough spots or pitting, white
powder deposits—frequently aluminum oxide—or heavy discoloration. If any of these signs are
evident, do not run the rotor. Contact your Beckman Coulter representative for information
bout the Field Rotor Inspection Program and the rotor repair center. To reduce the potential
for corrosion, clean buckets or carriers thoroughly immediately following a tube or well plate
breakage. Be sure to remove all glass particles from buckets or carriers.

Safety Notice
Safety Notice
• Components or accessories designed for other rotors may cause rotor mishap if used in this
rotor. Use only components and accessories that have been designed for use in this rotor. The
safety of rotor components and accessories made by other manufacturers cannot be ascertained by
Beckman Coulter. Use of other manufacturers’ components or accessories in the rotors may void the
rotor warranty and should be prohibited by your laboratory safety officer. If tubes, microplates, or
other labware made by manufacturers other than Beckman Coulter are used, reduce rotor
speed to prevent breakage. The strength of glass and plastic tubes can vary between lots, and
will depend on handling and usage; we highly recommend that you pretest labware in the rotor
using water samples to determine optimal operating conditions. Scratches (even microscopic
ones) significantly weaken glass tubes.
• Do not substitute a metal fastener for the plastic tiedown nut supplied with the rotor. If a tie
down nut comes off the shaft during centrifugation, the plastic nut furnished will break apart
in the chamber, causing minimal damage to the instrument. A loose metal object could
substantially damage the rotor, chamber, and lid, and could potentially escape the chamber
into the laboratory, causing personal injury or property damage.
• The rotor must be run with a full complement of buckets and/or multiwell plate carriers
attached to the yoke. You can run four buckets, four multiwell plate carriers, or two buckets
and two carriers (with like components loaded opposite each other). If only two buckets are
loaded with blood bags, bottles, or modular disk adapters, the other two buckets should contain
at least a minimal “blank” load (e.g., empty modular disk adapters) to achieve optimal results
and to avoid rotor imbalance.
• The maximum allowable run speed (3750 rpm) listed in the rotor specifications is for operation
when all conditions are within the standard specifications (using buckets). Maximum allowable
run speed when using Micro Plus multiwell plate carriers is 3250 rpm. Do not overload the rotor
without reducing the speed (see SPEED DERATING). Failure to derate will reduce the safe useful
life of the rotor.
• If disassembly reveals evidence of leakage, you should assume that some fluid escaped the
rotor. Apply appropriate decontamination procedures should be applied to the centrifuge and
accessories.

Relative Centrifugal Field (RCF) is the ratio of the centrifugal acceleration at a specified radius and speed (rω
2
) to the standard
acceleration of gravity (g) according to the following formula:
where ris the radius in millimeters, ωis the angular velocity in radians per second (2πRPM /60), and gis the standard acceleration
of gravity (9807 mm/s

GH-3.8 Rotor
Description
Description
Specific information about the GH-3.8 rotor is given here. Information about the use and care of centrifuges
is contained in the individual instrument instruction manuals, which should be used in combination with
this manual for complete centrifuge and rotor operation information.
The Rotor
The GH-3.8 rotor, rated for 3750 rpm, is used in Beckman Coulter Allegra 6 series, GS-6 series,
Spinchron series, and GP series centrifuges. This four-place swinging bucket rotor carries a wide
range of tube and bottle sizes (from 1.5 to 750 mL) or single- to quad-pack blood bags in buckets, as
well as 96-well multiwell plates in specially designed carriers. This rotor rapidly sediments protein
precipitates, large particles, cells, and cell debris. It can also be used for binding studies and for
separating serum from whole blood.
The rotor yoke is made of stainless steel. Either buckets or multiwell plate carriers, both made of
anodized aluminum, may be run by placing them over pivot pins on the arms of the yoke. Both
buckets and carriers swing out to a horizontal position during centrifugation.
CAUTION
Although rotor components and accessories made by other manufacturers may fit
in the GH-3.8 rotor, their safety in this rotor cannot be ascertained by Beckman
Coulter. Use of other manufacturers’ components or accessories in the
GH-3.8 rotor 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.
Buckets and Accessories
Several types of labware can be placed in the buckets, depending upon your application: modular
disk adapters (for tubes of various sizes), bottle adapters, blood bag cups, and Aerosolve cannisters
(when aerosol containment is required). Bucket covers are also available as an aid toward
containment.
Modular Disk Adapters
Tubes are supported in modular disk adapters, which can also serve as tube racks in the laboratory.
The adapter disks are color coded by the tube size they accommodate (see Table 2); the number of
disks used in an adapter assembly depends upon the length of tubes used. A tube decanter is
available to hold either 10-mm or 12-mm tubes securely in the blue adapter, allowing all the tubes
to be decanted at once. Additionally, 1.5-mL Microfuge tubes can be run using a special plate that
fits on top of the blue adapter. Both of these accessories are described in Table 2. Beckman Coulter
tubes and bottles available for use in the GH-3.8 rotor buckets are described in Table 3.

PN GS6-TB-003MD
1-4
GH-3.8 Rotor
Description
Bottle Adapters
Bottles are supported in polypropylene adapters that fit inside the rotor buckets. The adapters are
ribbed for strength and accommodate three bottle sizes, including one conical bottle (see Table 2).
Blood Bag Cups
Polypropylene cups provide support for blood bags in the rotor buckets. Blood bag cups are
available in two sizes: one for single- or double-pack bags, and one for triple- or quadpack bags (see
Table 2).
Bucket Covers
Transparent covers made of a high-impact plastic are available for the GH-3.8 rotor buckets. Each
cover requires an O-ring (made of ethylene propylene) that seats on a ledge inside the bucket. The
covers are held in place by attached latches. Although the covers are not designed to contain aerosols
that may result from tube breakage, they will contain most liquids and broken tube particles,
reducing the need to clean the centrifuge chamber, and allowing you to take appropriate
precautions before opening the covers in the event of tube breakage.
Aerosolve Cannisters
Aerosolve cannisters, designed to minimize aerosol leakage and liquid spills, can be used in the GH
3.8 buckets when this type of containment is required. The cannister was tested
*
to demonstrate
containment of microbiological aerosols under normal operating conditions of the associated
Beckman Coulter centrifuge, when used and maintained as instructed. Aerosolve cannisters hold a
variety of tube sizes in racks, or they can be used as 500-mL wide-mouth bottles.
* Validation of microbiological containment was done at an independent third-party testing facility (CAMR,
Porton Down, UK, or USAMRIID, Ft. Detrick, MD, U.S.A.). Improper use or maintenance may affect seal integrity and
thus containment.

CAUTION
Do not run chloroformed samples in Aerosolve cannisters. Chloroform vapors can
damage the cannister material.
Micro Plus Multiwell Plate Carriers
Figure 1 The Micro Plus Multiwell Plate Carrier
Micro Plus multiwell plate carriers (see Figure 1) are used by installing them on the pivot pins in
place of the buckets normally used with the rotor. Micro Plus carriers are made of aluminum, and
are black-anodized for corrosion resistance. The design of this carrier allows higher operating
speeds than were possible in older carrier designs. A blue thermoplastic base is used to house the
multiwell plates. A flexible plastic pad between the base and the plate(s) supports the plates during
a run. Each Micro Plus carrier will accommodate a deep-well multiwell plate, or can run up to three
96-well microplates (when more than one are run, one plate is placed directly on top of the other).
Refer to Table 4 for a list of labware that can be used with the carrier. Multiwell plates will break if
g-forces are too high. Rotor speed must not exceed 3250 rpm when Micro Plus carriers are run, and
additional speed reduction is required if maximum load limits (500 grams per carrier) are exceeded.
