ACCU-CAP
Cassette Inserts
Gravimetric Sampling —The Better Way
- Contain entire sample
- No loss of sample when removing filter from cassette
- Static-dissipative material prevents loss of fiber due to static
- Permit in situ extraction of contaminant
- Ideal for sampling wood and paper fibers
- Available for 25- or 37-mm two-piece cassettes
- Preloaded, preweighed PVC membrane certified to 0.1-mg
accuracy available
ACCU-CAP™ * is gravimetric sampling
made easy. Ideal for sampling fibrous and static dust for gravimetric
analysis, the ACCU-CAP dome-shaped filter capsule is molded of clear
static-dissipative plastic and heat-sealed to a filter (see Filter
Choices for ACCU-CAP below). ACCU-CAP is available for use with
25- or 37-mm two-piece cassettes with a support pad.
* ACCU-CAP is a trade name of Omega
Specialty Instrument Co., a member of the SKC family of operating
companies.
Gravimetric Sampling Made Easy
ACCU-CAP inserts are so easy to use. Simply open a two-piece cassette,
insert a support pad on the bottom section (outlet) of the cassette
followed by the ACCU-CAP with the bubble facing up. Press on the
top section (inlet) of the cassette. The opening on top of the ACCU-CAP
aligns with the inlet opening of the cassette.

The ACCU-CAP Advantage
- Static-dissipative material eliminates loss
of sample through fibers clinging to the cassette to ensure analysis
of the complete sample.
- No loss of sample. The all-in-one ACCU-CAP insert
is heat-sealed to a filter so there is never loss of sample because
the filter and sample are always encased in the ACCU-CAP dome.
ACCU-CAP even permits in situ extraction of contaminants.
- Choice of filter material and pore sizes means
ACCU-CAP can be used for a variety of applications.
- Easy-to-use ACCU-CAP simply fits as a middle
section in a two-piece cassette.
Using ACCU-CAP Cassette Inserts
ACCU-CAP cassette inserts are used with a two-piece cassette with
support pad. Simply open the cassette and insert ACCU-CAP between
the cassette's inlet and outlet sections. Sample as you would with
a filter in a closed-faced filter cassette and according to method
specifications.
One ACCU-CAP capsule retains the entire sample. The total weight
of the ACCU-CAP capsule is <300 mg for the 37-mm and <200
mg for the 25-mm
ACCU-CAP Means No Sample Loss
Problem: Dust particles such as powders,
wood, and light metals become statically charged due to the manner
in which they are generated, i.e., during grinding, woodworking,
or cutting. Sample loss can occur when these statically charged airborne
particles are drawn into a plastic cassette and adhere to the inside
of the cassette. To resolve this, cassettes are sometimes rinsed
to remove the particles from the sides. However, this step can result
in a diluted sample. Another point of sample loss due to static buildup
is during removal of the filter from the cassette. Particles may
be pulled off the filter and remain in the cassette.
Solution: ACCU-CAP! With ACCU-CAP, the
entire particle sample is captured inside the one-piece ACCU-CAP
capsule. No loss here! ACCU-CAP is also versatile; If an in situ
contaminant extraction is required, perform it easily inside the
ACCU-CAP capsule.
