A common need in many quality control or quality assurance settings is to be able to collect periodic samples.
These may be of waste streams, of source materials, or from a reactor to verify its progress.
While a standard laboratory fraction collector can be used for continuous collection tasks,
if you want smaller, periodic samples you will need to use a real interval sampler.
The IS-95 Interval Sampler is ideal for taking periodic samples of liquids. Simply provide
the interval for sampling and the sample size and it will do the rest. It can control a valve
for sampling from a low pressure line or elevated tank; it can also control a pump for situations
where the sample has to be lifted to be collected.
The IS-95 Interval Sampler includes a drop counter and drop former. This allows you to size your
samples based on either the number of drops or on the time of collection. If you require large
samples, you can even have a single collection span several tubes.
The IS-95 Interval Sampler includes remote control capability. An external controller can start
and stop the sampler, as well as follow its progress as it collects samples. Outputs indicate
when a sample is being collected as well as when a tube or rack change is occurring. Inputs are
available to start a collection run and to force a tube advance.
The IS-95 can collect up to 173 samples in 12 or 13 mm diameter tubes. Racks holding different
sized tubes are also available. The IS-95 is sold without a rack set, you will need to select
the rack set most suitable for your collection vessels and purchase it separately.
The diverter valves can be used to interrupt a flowing stream for collection. When not being
collected, liquid will flow through the valve along its normal path. When material is being
collected, the entire flow will be diverted to the sampler.
The shutoff valve is used to not divert the entire flow or to sample from a low pressure
container. A "T" fitting is placed in the line and the shutoff valve is connected to
one leg. When collecting, the shutoff valve is opened and some of the flow goes through
the valve to be collected while the rest continues it's normal path.
