Product information "Bürkle Multi Sampler Multi-stage Sampler, V4A stainless steel/PTFE, 710 mm, 5316-0085"
Anyone wishing to take samples from several depths or layers from a sack, barrel or silo in a single operation will need a sampler with several separate collection chambers. The Multi Sampler V4A/PTFE opens and closes its chambers via a rotary movement of the handle and releases each sample only at the desired depth, rather than collecting it as soon as it is inserted.
Stainless steel with a PTFE core for reduced weight
The tube is made of V4A stainless steel (1.4404) with a PTFE core. This combination brings together the chemical resistance of stainless steel with the lower weight of PTFE, making the sampler easier to operate than a version made entirely of stainless steel. For businesses that use the sampler several times a day, this makes a noticeable difference to its ease of use. At the same time, this version is more cost-effective than the Multi Sampler variant in V4A made entirely from stainless steel.
Small gaps to prevent carry-over
The gaps between the collection chamber and the outer tube have been deliberately kept small. This reduces the risk of particles from one chamber entering another zone when the tube is withdrawn, thereby distorting the results of the zone analysis.
Two sizes, with three or five chambers
The shorter version, with a penetration depth of 710 millimetres, has three collection chambers, each with a capacity of 17 millilitres, totalling 51 millilitres. The longer version, with a penetration depth of 1,355 millimetres, has five chambers of the same size, totalling 85 millilitres. Coloured caps for colour-coding make it easier to identify samples when several samplers are in use simultaneously. The choice of length depends primarily on the height of the container in question and the number of zones to be tested.
Sealing and cleaning
The seal is made of acrylonitrile-butadiene rubber (NBR). It ensures that the chambers seal reliably when closed and that no sample leaks between two zones. The 25-millimetre tube diameter allows for cleaning with a brush or cloth, even between successive sampling operations on different materials. After autoclaving, the sampler is ready for use with the next batch.
Practical example: Goods receipt
When a pallet of sacks containing raw materials arrives at the goods-in department, the Multi Sampler can be used to check in a single operation whether the material is uniform throughout the entire height of the sack. If the chamber samples differ significantly from one another, for example, because heavier particles have settled at the bottom of the sack, this is an indication of segregation, which would go undetected if only a single sample were taken from a single depth.
For which samples is the Multi Sampler suitable?
Unlike a sampler with just a single collection chamber, the Multi Sampler provides a zone profile across the penetration depth in a single operation. If, on the other hand, only a targeted sample from a single depth is required, the Uno Sampler target-point sampler from the same product range is sufficient. If the sample is intended to represent the entire layer height rather than individual zones, the V4A All-layer Sampler is more suitable.
Typical applications
- Zone profiles made from bulk material in sacks, drums, silos or big bags
- Quality control of homogeneity based on the fill height
- Sampling in the food, pharmaceutical and chemical industries
- Frequent sampling where weight and handling are important factors

Service and Procurement
Whether the V4A/PTFE version or the variant made entirely from stainless steel is more suitable depends on the frequency of use and the requirements in terms of weight and durability. We can advise you on choosing between the two versions and order each size individually. Our team is on hand to answer any queries you may have.
