Bürkle Uno Sampler Target-Point Sampler, V4A stainless steel/PTFE, 430 mm, 5316-1055

Not every sampling operation requires a depth profile across multiple levels. If only a single, targeted sample is required from a specific zone of a bag, drum, silo or stockpile, one collection chamber is sufficient. The Uno sampler opens exactly one chamber at the desired depth and provides a spot sample which can be analysed individually or combined with other spot samples to form a composite sample, depending on the requirements of the test specification.

One chamber instead of several zones

Unlike the Multi Sampler with three or five collection chambers, the Uno Sampler has just a single chamber. This makes it the simpler and more cost-effective choice when a complete zone profile is not required, but rather a specific sample from a particular depth or zone. For operations that predominantly take individual samples, the simpler design is also less prone to operator error than a device with multiple chambers.

Combine several Uno Samplers to create your own profile

Coloured caps distinguish between different Uno samplers when several samplers are used simultaneously at different depths within the same container. This allows a customised depth profile to be created without being restricted by the fixed chamber layout of a Multi Sampler, and individual target-point samples can be analysed separately if required, rather than being automatically mixed. This is useful when the depth intervals are to vary on a case-by-case basis, rather than being fixed within a single device.

Material and seal

As with the Multi Sampler, the tube is made of V4A (1.4404) stainless steel with a PTFE core, whilst the seal is made of acrylonitrile-butadiene rubber (NBR). This combination keeps the sampler easy to handle whilst also chemically resistant to most bulk materials and cleaning agents, which is particularly beneficial when the chamber is frequently screwed on and off.

Two sizes with different penetration depths

Two penetration depths are available: 430 millimetres with a sample volume of 14 millilitres and 710 millimetres with a sample volume of 17 millilitres. The shorter version is suitable for shallower containers such as sacks, whilst the longer version is designed for deeper drums or silos where the target position is further down. The correct length is determined solely by the depth of the target position within the respective container, not by the volume of sample material required.

Use in food and pharmaceutical companies

According to Bürkle’s labelling, the material of the Uno Sampler is suitable for food. According to the manufacturer’s specifications, the sampler is also manufactured according to a DIN standard; we provide the standard number on request. For applications with higher hygiene requirements, the manufacturer states that it is autoclavable, so that it can be fully reprocessed between different materials.

Practical example: Raw material inspection

If, upon delivery, the aim is simply to check whether the material at a critical point in the drum, for example, near the bottom, meets the specifications, a single spot sample is sufficient and can be taken more quickly than a complete zone profile involving several chambers. The Uno sampler provides precisely this single sample without the need to sample and analyse the remaining zones, which reduces the testing effort per batch.

Typical applications

• A targeted individual sample taken from a specific depth or zone of a bulk material
• Combining several Uno Samplers to create a customised depth profile
• Quality control of raw materials in sacks, drums, silos and big bags
• Situations in which a complete zone profile is not required

Service and Procurement

If you regularly require a complete zone profile, the Multi Sampler V4A/PTFE is better suited. Alternatively, for pharmaceutical applications requiring a sealed sample chamber, the Novartos Uno Pharma zone sampler is a suitable option. We can advise you on your selection and order each size individually.
