Spectra/Chrom® IS-95 Interval Sampler

The IS-95 Interval Sampler The IS-95 Interval Sampler is CE marked. The Spectra/Chrom IS-95 Interval Sampler is designed to take periodic samples of liquids. The size of the liquid sample may be set in terms of time or a number of drops (the drop counter is included).

For sampling from reservoirs, the IS-95 can control a pump, enabling it to run either only during each sample period or over the course of the sample run.

For sampling from enclosed flowing streams (in tubing or piping), the IS-95 can control an electric solenoid valve or other device to divert either all or part of the flow to the sampler.

The IS-95 Interval Sampler is ideal for use in quality assurance or monitoring applications where a product or waste stream must be periodically monitored to verify its composition. It can collect up to 173 samples of uniform size at a programmed interval. The maximum size of the sample will be dependent upon your collection vessels. If desired, the interval sampler can have a single sample 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.

The IS-95 is designed to be a laboratory instrument and as such it should be used indoors in a clean, temperature and humidity controlled environment. It is not designed to be used outdoors.

124848 2-Way valve. May be used with low-pressure enclosed streams. This 2-way valve is connected between the flowing stream and the sampler and when opened by the sampler it allows a portion of the flow to be collected. This valve is rated to 30 psi and comes with fittings for 1/8 inch OD, 1/16 inch OD and 1/16 inch ID tubing. 449.00
124849 3-Way valve. May be used with low-pressure enclosed streams. This 3-way valve is connected in series with the flowing stream and when opened by the sampler it forces the entire stream to be collected by the sampler. This valve is rated to 30 psi and comes with fittings for 1/8 inch OD, 1/16 inch OD, and 1/16 inch ID tubing. 427.00
124815 Pump cable. This cable may be used to control a Spectrum MP-1 or MP-2 pump for use as a sampling pump. The pump may be programmed to run either only during the sample periods or until the last sample is collected. 121.00
