Microvacuum Cassettes

SKC Microvacuum Cassettes enable efficient collection of asbestos or fungal spores. Available with an MCE or polycarbonate filter each microvacuum cassette features a microvacuum nozzle for sampling of settled dust on surfaces. The contaminants are collected using a high flow pump (10 L/min), whilst the nozzle enables easy sampling on irregular surfaces such as carpet. They are specified in ASTM D5755 and D5756. Use a Template to define an area for analysis of the collected sample.

ISO-CHEK Cassettes

Suitable for most isocyanates, the patented ISO-CHEK sampling system uses a two-stage filter that results in the simultaneous collection and separation of vapour from aerosol at the point of collection.

ISO-CHEK Cassettes
ISO-CHEK Cassettes
  • Accurately samples diisocyanates: HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI
  • The only filter-based system that simultaneously traps and separates both monomers and oligomers
    • For better determinations of control strategies
  • Decreases sample preparation and analysis time by 40% compared to other methods
    • Pre-made calibration standards are available
  • Highly stable — minimizes storage and handling
  • Highly sensitive analysis provides detection limits below current regulated exposure levels
    • Ideal for occupational sampling and environmental surveys
    • Requires only a 15-minute sample time
  • Meets the specifications of several methods
    • ASTM D5932 for 2,4, 2,6-TDI
    • ASTM D6561 for HDI
    • ASTM D6562 for HDI

SureSeal Cassette Blanks

Cassette blanks are two or three section housings for filters. They hold the filter securely in place during sampling and are ideal for personal sampling.

Opaque filter cassette blanks are designed to handle light-sensitive compounds such as PNA (Paraffins, Naphthenes and Aromatics) hydrocarbons.

All SureSeal cassettes are inspected to meet a vacuum leak test of <1 inch Hg delay per 30 seconds when subjected to 24 inches Hg vacuum and a pressure decay of 1 psi per 30 seconds when subjected to 5 psi pressure. SureSeal Leak-free cassettes require the use of a SureSeal Cassette Opener.

Filter Supports

Various materials are used to support filters during sampling.

  • Cellulose supports feature a smooth surface and uniform air flow distribution
  • Porous plastic pads are impervious to most solvents
  • Use stainless steel screens when cellulose or plastic will interfere with analysis
