The FreeGlide®

The FreeGlide® is a highly innovative sampler that has been developed by Sampling Systems. The FreeGlide is able sample powder as it falls down a pipe. After sampling, the sample is dropped down the chute into a bottle or other container.

The smarter way to sample

The FreeGlide® Powder Sampler is the only in-line sampling device that is guaranteed not to stick or jam during operation. The special diaphragm within the sampler keeps the powder away from the moving parts

How it Works



FreeGlide when not taking samples.
The full bore of the pipe is available for powder flow.

The cup extends into the pipe
and collects the sample from the falling powder

Sample Discharge
The cup retracts and is then inverted to allow the powder sample to fall down the discharge chute

FreeGlide® Sizes
The FreeGlide® inline powder sampler is available in a range of different sizes to suit different pipe diameters from 100mm diameter upwards.

Sample Collection

There are several methods of collecting the powder sample. The most common system is to clamp a bottle adapter to the end of the discharge chute. The bottle then screws into the bottle adapter. If a more high containment system is required then see the Split Butterfly system described below.

High Containment Sample Collection
Sampling Systems are proud to offer the ChargePoint Split Butterfly Valve for use with the FreeGlide Sampler. The ChargePoint Split Butterfly Valve clamps on to the bottom of the discharge chute.
