Dangerous liquids must never be dispensed by simply pouring them out from a bottle, barrel or other container. Even the use of a funnel does not provide the required degree of safety when bottling dangerous liquids. Inadequate liquid dispense procedures can lead to:

• Increased accidental risk of slipping on wet or dirty floors
• Skin irritation or more extreme toxic effects from chemical spills
• Health hazards from harmful vapours

Bürkle offers a wide range of pumping devices for manually dispensing liquids from containers, canisters, drums and tanks.

Pump capacity

Electric pumps are the first choice for dispensing large quantities of liquid at a fixed location. Their higher pumping capacity saves time and requires less manual effort. However, the purchase of an expensive electric barrel pump is not always practical or economical; for example, there may no on-site electrical supply, especially outdoors or in a materials storage facility. So, manual pumps are an interesting alternative to electric pumps for filling off small quantities due to their independence from a power supply, and also at a much reduced cost.

Container size and container type

Pumps that work according to the excess pressure principle are suitable for dispensing required quantities from canisters and small drums up to a capacity of approximately 60 litres. Air is pumped into the container using a pumping ball or pumping piston. This creates excess pressure in the container and the liquid is forced out via the immersion tube.

When sampling, a small, randomly selected amount is taken from a larger overall quantity. These samples often serve as the basis for the quality assurance protocols, and so the correct procedure for taking spot samples is a critical matter, because only with representative and authentic samples can reliable information about the quality, properties or composition of a particular material be assessed.

Bürkle offers a wide range of disposable and sterile sampling equipment for bulk goods, liquids, viscous substances, soil, ice and meat with comprehensive accessories and ancillary products.

Choosing the right sampling equipment depends on many different selection criteria. These include the material properties of the sampler as well as on the type of sampling, the container or the site where the material under test is stored, and the frequency with which the sampling is carried out. In addition to individual requirements for sampling, all equipment should fulfil the basic principles outlined below:

Sampler material

All sampling devices must themselves be manufactured from inert materials which pose little or no risk of contamination or reaction with the material actually under test. Note that an 'inert' sampler is partially defined by the material it is destined to test. As a general rule, samplers made of stainless steel and high-quality plastic such as PTFE are the most suitable.

Reusable versus disposable samplers

With traditional reusable samplers, it should be easy and quick to clean reusable sampling equipment and, under certain conditions, to sterilise it. As an alternative to reusable devices, especially for the food industry, Bürkle offer sterile-packed disposable samplers which can be disposed of after use.
