1. HAZARDOUS LIQUID SAMPLING SYSTEMS
Dopak manual industrial sampling systems for hazardous chemicals improve safety and reduce spills because they use the patented Dopak needle assembly – feel free to contact us to discuss the details.
Hazardous chemical industrial sampling systems from Dopak are installed worldwide in all sectors of the process industry and these can be installed to a pipeline or to a tank. The sampling connection in oil and gas applications can be very similar to connections in petrochemical, chemical or even pharmaceutical applications. We have standard connections available to suit all industrial sampling applications.
With a Dopak sampling system you can take a hazardous flowing liquid sample safely and cleanly with no spills using our septum sealed sample bottles. Below are details of types of sampling in analytical chemistry from Dopak, take a look and get in touch for datasheets, price and delivery details;
2. HAZARDOUS GAS SAMPLING SYSTEMS
Gas sampling systems with externally coupled valves (gearbox) to take representative samples of gases in sample cylinders. The Dopak S32-G type samplers are built from high quality stainless steel 316. Installation is using threaded connections, compression fittings or flanges.
Easy to use systems with one handle operation providing optimum safety for the operator and the environment. The Dopak S32-LG type samplers are supplied as standard with a manual handle but a spring return handle is a possible option and improves operator and process safety. Purge options are again available.
3. SAMPLING BOTTLES AND CYLINDERS
We have an extensive range of chemical sample cylinders and they are suited for collecting samples of hazardous gases. Our cylinders are perfect for safe transport and chromatographic laboratory analysis. The type of chemical sample cylinder we offer are available in different volumes and material of construction.
Chemical sample cylinders are used for samples with high vapour phase, gas and liquefied gas and are equipped with a needle valve on each side of the double ended sample cylinder along with a set of quick connect couplings and also a carrying handle.
A outage tube can also be included depending on the type of sampling application in which the cylinders are to be used. Additionally cylinder or bypass lines can be fitted onto the sample cylinder and overpressure protection devices such as a relief valve or a rupture disc.
External cylinder surfaces can be glass coated or coated with PTFE to provide a nonstick surface, which aids in cylinder cleaning.
4. SAMPLE BOTTLE EMPTYING SYSTEMS
So, you take a chemical sample. You have analyzed it in the laboratory, now what? How to dispose of the sample in a way that is safe for the environment and safe for the operator. Well, why not just return it to the process where it came from. Using the superb Liquid sample recovery system from Dopak
This great solution is available from the guys at Dopak with their liquid sample recovery system.
The Dopak SRS offers the ability to recover a liquid sample from the sample bottle. Without the risk of spillage or contamination. Applications for this system can be found in plant laboratories. Furthermore the unique design offers a one handle operation by multiple valves. In addition, the nitrogen purge not only assists in driving the liquid out of the sample bottle, but also cleans the whole system including needle assembly and sample bottle.
How does it work?
- Provide a new septum on your sample bottle. Insert the bottle, with cap and septum into the sleeve. Put the special bottle retaining clip in place and turn the thumb screw until the bottle is fixed in the sleeve.
- Turn the sleeve upside down. Fix the special bottle retaining clip in the terry clips. Turn the handle to the “recovery” position, allowing the inert gas to drive the liquid out of the sample
bottle to the process-out connection. This position can be held for any required time. - Turn the handle to the “vent” position allowing the sample bottle to depressurise.
- Turn the handle to the “off” position and turn the sleeve back to the normal position. Unfix the
thumb screw, remove the bottle retaining clip and pull the bottle out from the sleeve. The septum
reseals automatically.
A simple way to return used samples back to the process without spills and additionally without emissions. Safe for the operator. Safe for the lab and additionally great for the environment. Costs in disposing of samples can also be reduced. So if you take samples of potentially hazardous liquids and need a great stand alone solution for the safe disposal of these samples then look no further than the Dopak sample recovery system.
5. SAMPLE CYINDER EMPTYING SYSTEMS
The Cylinder Emptying System empty a cylinder containing (Liquefied) Gas without the risk of spillage or contamination.
- Closed emptying/no spillage
- Depressurising of quick connect couplings
6. INDUSTRIAL POWDER DOSING SYSTEMS
Effective batch dosing systems in the UK process engineering sector guarantee production levels are accuractely maintained. They can be used in a wide variety of applications such as liquid fats, oil, molasses, lecithin, creams, acids, amino acids and solvents.
Accuracy is important for effective homogenization and emulsion of the liquids being processed providing perfect distribution of the liquids inside the mash during the mixing phase, regardless of the type of mixer being used.
An effective batch dosing system is suitable for handling any kind of process liquid with any type of viscosity. A multipurpose solution which will give the client 5 key benefits.
- Management cost reduction
- Improved quality
- Less dirt in the batch mixer
- Reduced lumps and fines
- Increased production
7. INDUSTRIAL LIQUID DOSING SYSTEMS

- Management cost reduction
- Improving feed quality
- Less dirt in the batch mixer
- Reducing lumps and fines
- Increasing production
- Increasing moisture retention by homogenising oil and water based liquids
8. INDUSTRIAL MIXING SYSTEMS
he homogeniser EML, thanks to the high cutting effect obtained from the mechanical and hydraulic work of the Rotor and Stator, creates a highly mixed product, reduces the size of particles, and eliminates suspended solids and lumps.
For this reason the installation of the EML in the production line allows to reduce the working times and increase the quality of the final product.
Homogenisers can be installed online or used to recycle products.
Thanks to the pump effect, it is possible to install the machine without the use of pumps, in the case when very viscous products are used, it may be better to install a pump on line.
EML is suitable for any liquid, creams and pastes or for dispersion of the powders in the liquids.
The EML can be designed for the special need of : Food, animal feed, chemical, paint, ceramic markets
9. INDUSTRIAL SPRAYING SYSTEMS
- Suitable for any type of liquid with any viscosity
- Nebulize in small particles the liquids for perfect distribution
- Can spray more liquids at the same time
- No need for high pressure to nebulize the liquids
- Flow rate can range from 0,1 up to 40 litres per minute, always guaranteeing a good nebulization
- Thanks to the large hole injector, blockage of the nozzle is rare
- Very easy to clean
10. INDUSTRIAL COATING SYSTEMS
The coating system DRUM COATER is a complete machine, able to coat in line pellets, kibbles, potatoes sticks, cubed vegetables, oat flakes, corn flakes, puffed rice, cereals, rice etc.
It used for:
- The treatment and tanning of seeds or for the addition of pesticides.
- For the addition of liquid additives such as enzymes, fat, digest, spices, oil, olive oil, antibiotics, vitamins, colours, chocolate, caramel, sugars, etc.
- Adding powder additives such as flavours, spices, salt, cocoa, enzymes, antibiotics, colours, etc.
The drum has a system valve on the outlet, allowing small batches of product to be mixed with a longer retention time.
This ensures an excellent coating over the entire surface of the product, even with small percentages of additive.
The system is composed of:
- Top hopper with load cells to keep the level of the product constant
- Weighing screw to detect the amount of product to be coated
- System for the preparation and dosage of the additive
- Complete with stainless steel or painted support structure, the rotating drum is driven by a gear motor, has a linear actuator to adjust the inclination of the drum, loading and unloading hoppers
- Complete with motorized or static sprayers.
- An electronic device used to identify the instantaneous flow of the product and to determine the right amount of additive imported by the operator, increasing or decreasing according to the product flow rate.
