    Chapter 1: Introduction About This Manual This manual is designed to help you learn how to install, use, and maintain your filtered enclosure. Instructions for installing optional equipment or accessory carbon filters on your filtered enclosure are also included. Chapter 1: Introduction provides a brief overview of the filtered enclosure, explains the organization of the manual, and defines the typographical conventions used in the manual.

    Chapter 1: Introduction Appendix C: Specifications contains the electrical requirements for filtered enclosures. Wiring diagrams are also included. Appendix D: Quick Chart provides an airflow table and test data for the filtered enclosures. Appendix E: References lists the various resources available that address laboratory ventilation and biosafety.
  • Page 10 Before you install the filtered enclosure, you need to prepare your site for installation. You must be certain that the area is level and of solid construction. In addition, a dedicated source of electrical power should be located near the installation site to power the filtered enclosure, balance and other apparatus.

  • Page 11: Chapter 2: Prerequisites

    Chapter 2: Prerequisites Support, Vibration and Movement Requirements At a minimum, the supporting structure usually consists of a base cabinet and chemical-resistant work surface. The ability for analytical balances to accommodate vibration varies with type and brand. More advanced balances have improved tolerance, however in the preparation of a balance enclosure site, please consider the following: Temperature Variation...

  • Page 12: Humidity And Static Electricity Requirements

    Humidity and Static Electricity Requirements Electrostatics can be troublesome in a balance enclosure. It is important to understand and, to the extent possible, control static charges. An electrostatic charged vessel, sample or enclosure can apply forces and lead to errors in weighing. The repulsion or attraction can be detected with micro, semi micro and analytical balances.

  • Page 13: Location And Air Current Requirements

    Chapter 2: Prerequisites The ability of a material to become polarized is a property known as permittivity. On highly insulative materials like acrylic, ions or charged molecules are strongly bound to the surface by polarization forces. The higher the force, the higher is the permittivity value of the material.
  • Page 14 The HEPA-filtered exhaust air can be recirculated into the laboratory or exhausted outside with the addition of the exhaust connection kit and remote blower listed in Chapter 7. The XPert Filtered Balance Station does not include the motorized impeller and must be exhausted to the outside by a remote blower. The XPert Filtered Balance Station remote blower may be switched from the blower switch on the enclosure.

  • Page 15: Electrical Requirements

    Chapter 2: Prerequisites Proper blower selection can be determined from these exhaust requirements and the total system static pressure loss. For outside exhaust, the enclosure must be connected to either a dedicated blower or a house exhaust system. Labconco offers accessory remote blowers listed in Chapter 7. Contact Labconco for blower sizing assistance.
