The Bottom Sampler acc. to Ekman-Birge is a quantitative sampler with precise sampling area to achieve nearly undisturbed samples in soft grounds. It consists of a sturdy-walled metal cabinet equipped with two spring-loaded jaws which are released by a messenger. Two light plates cover the top opening of the sampler to prevent the sample from being washed out during ascent.

The Bottom Samplers acc. to Van Veen are designed to obtain qualitative sediment samples with minimal disturbance from any desired depth. Their clamshell jaws remain open during descent and automatically close when the sampler touches the seabed and is pulled up, securing the sample and preventing wash-out. Heavy versions include additional lids or inspection windows, covered with stainless steel gauze and rubber flaps, that allow visual inspection before retrieval. Models range from light 5.5 kg samplers to heavy 60 kg ISO-compliant designs, providing versatile solutions for hydrographic surveys, aquatic research, and environmental monitoring in compliance with EN ISO 16665 standards.

The Integrating Water Sampler IWS III is a light and handy instrument for the acquisition of summing (integrated) water samples according to the EU-WFD (European Water Framework Directive). The integrated sample is automatically achieved in one single draft. There is no need for repeated operations of standard water samplers, followed by mixing procedures.
The sampling technique is very simple. An electric motor actuates a piston inside a transparent tube. A microprocessor controls the sampling procedure according to the pre-selected depth, time or spot scenario. A built-in high precision pressure sensor cares for accurate depth measurements. Power supply of the sampler is made by rechargeable lithium-ion batteries, using the safest chemistry currently available.

ICES standard for phytoplankton primary production measurements.
One of the most important marine processes is the formation of organic material resulting from the interaction of carbon dioxide, water and sunlight, a process known as photosynthesis. The ability to measure this process is of great importance when assessing marine pelagic systems. In practice the best way to measure photosynthesis is to look at the absorption of carbon dioxide. The high sensitivity of carbon dioxide absorption measurements allows to use this method under all circumstances. Neither low or very high algal concentrations nor low light conditions and low temperatures are restrictions for this method.
Based on the 14C method, using the absorption of the radio-active 14C isotope of carbon (Steemann-Nielsen, 1952), the ICES Incubator is the ICES standard for phytoplankton primary production measurements.The incubator shown here has been mainly developed for monitoring purposes. It should be used preferably for water samples taken from a mixed water layer with a fixed temperature. Measurements of the amount of phytoplankton (based on chlorophyll-a concentration measurements) should be carried out for interpretation purposes.
The ICES Incubator consists of an illuminated transparent plexiglass tank incorporating a turning wheel on which 12 experimental bottles can be clamped. The tank is filled with water which is set in motion by an adjustable circulating pump. Thus the turning wheel is set in rotation at speeds up to 10 rpm with the experimental bottles acting as paddles. Tank connections for a second water circulation allow for temperature adjustments of the water by using external tempering equipment.
The 12 experimental bottles of 50 ml capacity each have different optical coatings, so that each bottle has individual transmission rates and thus generating a number of 12 different irradiance (or light intensity) levels. The illumination unit is equipped with 10 fluorescent tubes with a wave spectrum according to ICES specifications, each can be switched individually. For higher irradiance levels a second illumination unit can be mounted onto the ground plate of the ICES Incubator.

The Improved Prokopack Aspirator Model 1419 was developed for indoor sampling of resting mosquitoes such as Aedes aegypti, anophelines, and Culex. Aspiration of resting adults produce collections of both sexes and all physiological stages directly from their resting sites, allowing better estimations of species diversity, abundance, sex ratio, age structure, and physiological status (Silver 2008). At 23 ounces (650 g) it is light weight and highly maneuverable; with the included extension pole the unit can sample from ground level up to 13 feet (4 m). This enables collections to be made on upper walls, ceilings, and under furniture. Also included with the 1419 is (1) a 12 volt 12 amp hr gelled-electrolyte battery, the extension pole, six collection cups and lids with stainless steel mosquito mesh, a universal voltage (input 100-250 VAC, 50/60 Hz) automatic charger with an output of 5.0 amps per hr) permitting complete recharging in 2.5 hours. Run time is four hours.
Our Prokopack aspirator incorporates several significant improvements to the original design. By optimizing the air flow we have improved intake air speed by 15%, reduced current consumption by 33% and thereby increased run time between battery recharging to four hours.
Using the supplied 12 volt 12 amp hr battery will provide the performance indicated below; the darker line is for the standard (mosquito) mesh screen in the collection cup, the lighter line reflects the fine mesh sandfly screen collection cup:

The New Standard Model 1012 Miniature Incandescent Light Trap offers 100% light output and maximum airflow for superior capture results. Its built-in programmable photosensor allows you to control any combination of motor and/or light on/off at dusk and dawn, making this trap a versatile and efficient tool for your mosquito and sandfly studies.
NOTE: Batteries are not included. Sold separately.
The Model 1012 trap emits 75% more light than any other incandescent trap on the market. Its new ABS rain shield and clear acrylic body reflect and transmit light downward and outward. The photosensor delivers 100% of the battery voltage to the light and motor, meaning the bulb produces bright white light as designed, not a dim yellowish glow.
By delivering 100% of the battery voltage, the motor RPMs are approximately 20% higher than in other miniature light traps. Together with our low-profile grill, airflow is substantially greater than other models.
The built-in photosensor can control any combination of motor and/or light on/off at dusk and dawn. You can program the trap into different modes without the need for small tools and without jumpers that can be lost.

A laser bird deterrent is one of the most effective and well-documented ways to repel pest birds. The bird repellent laser beams are able to keep pest birds (such as pigeons, blackbirds, ducks, sparrows and more) away without causing any harm to the birds or the environment. Additionally, our laser bird repellent products don’t produce any sound, so you can enjoy a bird-free space without the unwanted noise.
There are three versions of laser bird repeller products — one indoor model, one outdoor model and one all ambients model. Each laser bird deterrent system uses random intervals of red and green laser combinations to create an environment that birds hate, forcing them to search for different landing areas. The laser bird deterrent systems can work day (in low-light areas) or night with constantly changing patterns, preventing birds from acclimating to the repellent.
Laser bird deterrent products eliminate the need for harmful poisons, traps or pesticides. You can feel good about keeping pest birds at bay in a way that’s safe.
With a range of up to 10,000 square feet, the unrelenting red and green lasers will irritate birds, bats and small mammal pest species without harmful traps or chemicals. The powerful Class 3R “fat beam” laser diodes create multiple random patterns that prevent birds from acclimating, keeping them away permanently.
All lasers are pre-programmed and can be used night or day in darker areas. The indoor laser comes ready to mount with the included bracket, and the outdoor laser includes a base for easy installation. The convenient and flexible coverage makes laser bird control perfect for a wide array of locations. The lasers also include a 30-day satisfaction guarantee, so you can rest assured your unwanted guests will be gone for good!
