In-Stack Thimbles and Accessories
| Apex
Instruments stocks a variety of fiber thimbles for in-stack particulate
sampling. The thimbles are seamless, high purity filters and available
from a choice of two different materials: borosilicate glass fiber and
quartz fiber. borosilicate glass fiber thimbles are acid washed to
reduce the trace metal content to an absolute minimum. Quartz fiber
thimbles are strengthened with alumina and are prefired at
900°C for 2 hours during manufacturing to stabilize the weight
prior to use. The gas collection efficiency of the thimbles is 99.9%
(0.3 micron DOP). The 25x90mm thimbles specifically manufactured for
stack sampling and tapered for ease in loading. Cellulose thimbles are
available upon request. |

Thimbles |
|
Alundum® Thimbles are typically used for
in-stack filtration for process-engineering studies when a large sample
is needed for analyses. These thimbles are made from fused alumina
oxide and remain very constant in weight and can be re-used an infinite
number of times. We offer two different porosity thimbles that can be
used in our SFA-300 thimble holder. The medium porosity retain
particles 5 micron and larger and the coarse retain particles 20 micron
and larger.
