The only In-Line Powder Sampler guaranteed not to jam


The FreeGlide is a patented in-line sampler that can take samples of powders as they fall under gravity down a pipe.

  • Ideal for pharmaceutical and food applications
  • The sample is collected in a cup and so is not physically altered by the sampling process
  • The full bore of the pipe is available for powder flow in between taking samples

The FreeGlide has many features that make it ideal for use in hygienic GMP correct manufacturing areas.

The powder is kept out of the bearings by use of a special flexible membrane - this means the sampler will not get stuck during use.

The product contact parts are made from FDA acceptable materials

The FreeGlide is easy to strip down for cleaning between batches

FreeGlide® samplers are available to suit different pipe diameters and can be either manually or pneumatically operated.

The FreeGlide® is the smart way to take samples from free-falling powders in downpipes

Resting -
When the FreeGlide® is not in use the full bore of the downpipe is available for powder flow.
Sampling -
The sampling cup is extended into the downpipe to catch the product as it falls.
Discharging -
The sampling cup is then retracted and inverted. The powder sample falls down the discharge chute to where it is collected
