Uniform temperature distribution is maintained on the Temp-Zone area of the
work surface. Temp-Zone work area temperatures of 0.3-0.5°C are
maintained with the circulator heated to 37°C and within 0.3-1.6°C with the
circulator chilled to 3.7°C. Actual set points will vary depending on
variables such as sample tube rack, sample size, and length of tubing.
Safety Precautions
WARNING: The Biosafety Cabinet Biohazard Cabinet should be certified
by a certification technician before its initial use. The cabinet should be
recertified whenever it is relocated, serviced or at least annually thereafter.
Do not assume that filter integrity and airflow performance have not been
compromised during shipping.
Some internal components of the Biosafety Cabinet may become
contaminated during operation of the unit. Only experienced personnel
competent in decontamination procedures should decontaminate the cabinet
before servicing these components. If you have any questions regarding
certification agencies, or need assistance in locating one, contact Labconco’s
Product Service Department at 800-821-5525 or 816-333-8811.
DO NOT load more than 50 lbs. (23 Kg) in the work area. Exceeding this
limit may damage the work surface and its supports. Excessive weight in the
cabinet may increase the risk of it overturning, or failure of hydraulic lift
stands, resulting in the cabinet and stand overturning. If your application
requires loading more than 50 lbs., contact Labconco’s Product Service
Department at 800-821-5525 or 816-333-8811 for assistance.
Ensure that the Cabinet is connected to electrical service in accordance with
local and national electrical codes. Failure to do so may create a fire or
electrical hazard. Do not remove or service any electrical components
without first disconnecting the Biosafety Cabinet from electrical service.
Avoid the use of flammable gases or solvents in the Biosafety Cabinet. Care
must be taken to ensure against the concentration of flammable or explosive
gases or vapors. An open flame should NOT be used in the Biosafety
Cabinet. Open flames will disrupt airflow patterns, burn the HEPA filter
and/or damage the filter’s adhesive. Gases under high pressure should not be
used in the Biosafety Cabinet, as they may disrupt its airflow patterns.
HEPA filters only remove particulate matter. Operations generating volatile
toxic chemicals or radionuclides must be evaluated carefully.
The media of HEPA filters is fragile and should not be touched. Avoid
puncturing either HEPA filter during installation or normal operation. If you
suspect that a HEPA filter has been damaged, DO NOT use the cabinet;
contact a local certification agency or Labconco at 800-821-5525 or 816-333-
8811 for re-certification information.
