WS 316 SE Self-Emptying Sampler
The fully automatic bottle emptying and rinsing function makes the WS 316 SE ideal for surveillance and other applications where samples are not regularly retrieved. Bottles are filled in sequence, and then automatically drained and rinsed with clean water if samples have not been retrieved. They are then available for the next samples.
The WS 316 SE features the same benefits as the WS 316, and in addition offers the following functions:
- Direct distribution for 2 to 24 bottles to ensure samples remain free of cross-contamination
- Available with second sampling system and composite container for additional samples, such as event-proportional samples (see photo)
- Pull-out bottle tray for easy retrieval of samples
- Sample retrival at the touch of a button releases samples directly into transport container, without tap and therefore without cross-contamination
- If required, sample storage chamber can be provided with lock and/or monitoring of door movements
- Optional viewing window in door for sample storage chamber
- Additional monitoring of bottle fill level possible
WS 316 SR Self-Rinsing Sampler
With automatic rinsing of the complete sampling line (suction hose, metering glass and distributor hose) using clean water, the WS 316 SR is the ideal sampler for heavily soiled sample media. In addition to specifying the frequency of rinsing, the components to be rinsed can also be selected.
The WS 316 SR features the same benefits as the WS 316, and in addition offers the following functions:
- Separate drain for rinse water in sample storage chamber
- Drain position accessed directly by XY Distributor
- Numerous bottle combinations up to 35 x 1 l bottles; even customer-specific bottles can be used
- Available with warm water rinsing if desired, e.g. for greasy media
- Optional upgrade to system with automatic dosing of cleaning agent when rinsing
WS 316 EX II Interior Sampler
WS 316 EX II Interior SamplerEspecially in the chemical industry, sampling media can contain flammable substances and present an explosion hazard. In many cases, preventing ignition at the sampling point as well as in the sample storage area.
This variation of the WS 316 was developed for such applications, where only the sample storage chamber is classified according to the ATEX norm for Ex Zone II. The huge cost savings compared to a fully ATEX-certified sampler, as well as the outstanding quality, make the WS 316 EX II Interior a popular sampler among large international firms.
The WS 316 EX II Interior features the same benefits as the WS 316, and in addition offers the following functions:
- Sample storage chamber classified according to ATEX norm for Ex Zone II 3G Ex ic IIB T6-10=Ta=+60°C
- Pneumatically-operated distributor for direct bottle filling, thereby eliminating the need for a distributor plate and preventing cross-contamination
- Numerous bottle combinations up to 24 x 1 l bottles
- Various sampling systems available
- No recalibrating sample volumes after cleaning
- Available with Ex-proof heating
- Optional static cooling with evaporator plate encased in the rear wall
- If required, sample storage chamber can be provided with lock and/or monitoring of door movements
Monitoring Stations
Sampling and Water Quality Monitoring
Any WaterSam sampler can be upgraded to a monitoring station by connecting water quality monitoring instruments. A range of sensors and parameters are available to choose from, and measured values can be stored in the controller and easily retrieved.
Sensors can be positioned directly in the sample medium source, or installed in a monitoring vessel inside the sampler. Installation in a sampler offers the benefits of protection as well as easy access for cleaning and calibration.
The sampler can be set to take samples in case upper and/or lower parameter limits are exceeded.
If the sampler is equipped with an XY Distributor or an additional sampling system, event-based samples can be deposited in containers specially reserved for such a case.
- Monitoring equipment directly from WaterSam or according to customer request
- Intelligent sensors do not require an expensive transmitter
- Measured data can be logged
- Connection to existing monitoring equipment is possible

WS 98 F Freezing Sampler
The WS 98 can preserve samples by immediately depositing them directly in its cooler. The removable cooler can then be brought to the lab, ensuring that the cold chain is never broken. Thanks to the unique distributor system, a variety of bottles can be filled.
The WS 98 F features the same benefits as the WS 98, and in addition offers the following functions:
- Active refrigeration for sample cooling down to -22 °C
- Ability to power cooler with socket in vehicle to maintain cold chain during transport
- Sampler housing, frame and distributor made of stainless steel
- Controller and other electronic components protected in sampler housing
- No icing of fill opening
Sample Storage Cabinet
Due to its accurate temperature control, the WaterSam sample storage cabinet is well-suited to storing samples after they are removed from the sampler. Unlike a simple commercial refrigerator, it offers more room for samples so that even complete bottle sets in carrying trays can be accommodated.
- Available in two sizes, based on the WS 312 and WS 316
- Designed for outdoor and indoor installation
- Freely adjustable interior temperature with high accuracy; for ambient temperatures from -25 °C to +42 °C – optionally from -40 °C to +55 °C
- Optional relay for alarm when set upper or lower temperature limits are exceeded
