Product information "Bürkle PowderProof horizontal sampling lance, V4A/V2A stainless steel, granules, 5302-0301"
In the case of sacks or packaging that are inaccessible or difficult to access from above, a sampling lance – which has to be inserted vertically from above – is of little use. The PowderProof horizontal lance solves this problem with a lateral insertion: a motorised screw conveyor extracts free-flowing powder or granules directly from inside the sack without the need to open the packaging or tip it out.
Side entry instead of top access
The lance is guided horizontally through the bag wall or a side opening in the packaging until a penetration depth of 300 millimetres is reached. This is suitable for bags that are stacked or which, for other reasons, should not be opened from the top. The total length of the lance is 607 millimetres, with an outer diameter of 25 millimetres.
Motorised drive instead of a hand crank
A Bosch battery-powered drive unit drives the conveyor spiral in the lance and transports the sample material evenly from the bag into the sample bag provided. This makes sampling independent of the operator’s manual strength and, when taking repeated samples from the same material, ensures a more consistent extraction than a manual tool.
Two versions for powders and granules
The lance is available in two variants, each with a feed screw suited to the particle size of the sample material: one version for granules with a particle size of 2 to 4 millimetres, and one for finer powders up to 2 millimetres. Both versions share the same housing, drive unit and accessories; the only difference is the feed screw and, consequently, the weight (see table below).
Materials and cleaning
The parts in contact with the medium are made of 1.4404 (V4A) stainless steel; the remainder of the housing is made of 1.4301 (V2A). According to Bürkle, the lance is autoclavable and therefore suitable for areas with heightened hygiene requirements; a cleaning brush is included in the scope of supply. Bürkle also classifies the material as food-grade.
Replacing the feed spiral
The feed spiral in the lance is a wear part and can be replaced using the supplied pliers for the retaining ring. If you frequently switch between different materials or if the spiral wears out, it can be reordered individually without having to replace the entire lance, including the drive unit.
Typical applications
- Sampling of free-flowing powders and granulates from sacks and side-accessible packaging
- Incoming goods inspection for palletised or stacked bagged goods that are not to be opened from above
- Recurring sampling with a consistent flow rate thanks to the motorised drive
- Quality assurance in powder and granule processing, for example in chemical and food production facilities

Sample bags and accessories
The scope of delivery includes 100 sample bags, each with a capacity of 400 millilitres, as well as a bag retaining clip, which can be used to secure the bag to the lance during sampling. This means the lance is ready for use from the very first time it is deployed, without the need to procure suitable sample containers in advance.
Regulatory information
As the PowderProof horizontal lance is powered by a battery-operated drive unit, it is classified as an electrical appliance under the ElektroG. Information on returning the equipment at the end of its service life can be found under ‘Environment and Disposal’. The batteries supplied must not be disposed of with general household waste, but must be returned via standard household battery and rechargeable battery collection schemes.
Power unit in everyday use
Two batteries supplied with the unit and a rapid charger ensure that a flat battery can be quickly swapped for the second one during a longer sampling run, without having to interrupt work whilst the battery is charging. The adapter included in the scope of delivery connects the drive unit to the sampling lance and can be detached using the enclosed pliers for the retaining ring, for example for cleaning or replacing the feed spiral.
Service and procurement
For top-entry sampling into open containers, drums or big bags, the structurally identical PowderProof vertical lance is more suitable, with penetration depths ranging from 600 to 1,200 millimetres. The PowderProof feed spiral is available separately as a spare part for both lance types. For cohesive, clumping substances where a conveyor screw reaches its limits, the Scratcher powder sampler is more suitable. LT Laborhandel supplies both lance designs as well as suitable spare parts and, where required, tailors the configuration to suit different bulk materials.
