MPTS Sampling Device
Inline & sterile sampling
Dec provides various sampling devices from the vacuum type MPTS to a mechanical system to take samples inline directly from equipment such as dryers, mixers or from a pack-off line.
The selection of the sampling technology will be dictated from the type and conditions of the process to be sampled, the level of containment to be achieved as well as economical aspects.

The sampling procedure with MPTS is simplified, whether inline directly out of the process, from equipment with poor access, or, where personnel are not admitted for safety reasons.
Samples are taken instantly, thus giving a true image of the powder condition during the process (degree of mixture, humidity, homogeneity, etc.).
Samples are extracted and transferred to its final destination, whilst maintaining full containment, remaining homogeneous and representative as taken in dense flow, without using any mechanical device which could result in powder attrition.
Completely air tight, the system is particularly well suited for operation with toxic, radioactive or explosive powders.
It can be run with protective gas and be partly or fully integrated into a glove box or any other cabinet. MPTS Sampling Device takes a predetermined quantity of powder, even down to gram level, in a fully automated manner. From single shot to continuous sampling, the system is easily integrated into any process. MPTS also allows to take samples from a transfer pipe under pressure.
MPTS Sterile Sampling / Bottle Safety Cabinet
MPTS system can be used to take samples from sterile processes without breaking the sterile condition. A sterile barrier separates the system from the sampling process.
The vacuum generated by the MPTS prevents any process contamination. The system is fully automated with safety interlocks and an adequate valve arrangement for line clearance and sterilization.
The sampling bottle can be installed in a ventilated safety cabinet allowing full operator protection against bottle connection leakage or bursting.
The cabinet is connected to an extraction system thus maintaining a safe condition when removing and replacing the bottle. The panel includes a front window for a good visibilty during operation and a drain connexion for cleaning purposes.
Sampling Bottle Glove-Box
When sampling toxic powder, it is required to connect and remove the bottles in a contained manner.
Dec can provide compact and ergonomic glove boxes for the integration of the sampling bottle providing high containment of less than 0.1 µg /m3.
The glove box can be either passive or with an active filtration and ventilation system and includes RTP or airlock system for the introduction and removal of the bottles.
MPTS can be provided as a portable version for sampling from various equipment at different locations.
The control panel and the MPTS are installed on a trolley and the powder flexible hose can be directly connected to the equipment to be sampled.
In order to operate the system, it is only required to connect the trolley to vacuum, compressed air and, if required, to nitrogen in case the sampling must be done under inert atmosphere.
Piston / Spoon / Screw Type Sampling Device
Compact sampling devices which can be directly integrated into a chute to take sample from free falling powder.
The system is automated and includes a pneumatic cylinder to activate the internal sampling piston. The permanent sampling thief installed inside the chute is flushed back by the moving piston before the sample is taken which allows a perfectly representative sample.
The system handles multiple sampling.
Flexible Bottle Sleeve
Instead of using standard sampling bottles which need to be installed in a safety cabinet to guarantee its contained connection, a flexible liner system can be used.
This system allows to collect the sample into a sleeve which can be isolated and disconnected in closed manner by a specially designed clip system.
The LayFlat* system is suitable for the contained collection of powders and granules. (SS 1.4404 & sleeve LDPE)
