CRP Sampling, Sample Dispensing

Sample Dispensing tailored to suit process conditions
Depending on the properties and hazard risk of the sample to be taken CRP offers a variety of dispensing solutions to best suit your process requirements. CRP uses a modular dispensing connection on all its sampling equipment so that different dispensing options can be easily connected to the sampling system.

By using this modular sample dispensing approach we can best match the type of dispensing option supplied with the minimum of cost & effort to the customers specific requirements for containment and operator safety. At the forefront of this selection must be operator safety which is always our key focus.

Offers a simple sample dispensing method being a straightforward PTFE or stainless steel dip tube. The operator simply offers up a hand held sample bottle to the dip tube and operates the sample valve to acquire the sample. This is fine for samples which are not toxic or dangerous to the operator. The bottle vents freely into the atmosphere around the dip tube.

Threaded Bottle Connector

The most common type of sample dispensing supplie,a PTFE threaded bottle connector is supplied with the sampling valve. The operator screws the sample bottle up into the adaptor before taking the sample. The threads on the bottle adaptor are machined to suit the customers own sample bottle. The bottle adaptor has an integral vent supplies with a PTFE compression fitting and a short length of PTFE tube to carry fumes away from the operator. This can be piped into the site extraction systme if required.

Septum Capped Bottle Assemblies

The sample bottle is fitted with an aperture cap and septum to seal the contents of the bottle from the atmosphere. THe sample bottle is offered up to the septum assembly and pushed on to the two non coring needles which puncture the septem preventing fumes or sample media escaping from the sample bottle to the atmosphere. It also prevents the atmosphere entering and contaminating the sample.

Syringe Sampling

Syringe sampelrs differ from the other types of sample dispensing methods because no sample bottle is used. Instead the sample is drawn directly from the process and contained within a borosilicate glass tube within a syringe assemble. The sample is automatically taken from the sample valve when the syringe is offered up to its mount using a pin and cam arrangement. When the syringe is released the sample valve and syringe automatically close preventing any release of fumes or product. The sample is contained within a borosilicate glass tube contained within a sturdy stainless steel carrier. The syringe can then be taken to the laboratory and safely dispensed using the syringe dispensing attachment. Sample bottles can be contained within a safety cabinet to give additional protection.
