Watrex SPR-200 Solvent saver

Watrex SPR-200 Solvent Recycler is designed to save up to 90% of mobile phase during isocratic HPLC.

This Solvent Recycler saves up to 90% of mobile phase by redirection of the pure solvent to the solvent reservoir during the isocratic HPLC. The stand alone device is powered by 5 V DC from power adapter or from computer USB port. Working parameters (Threshold and Delay) are easily set on the display using a membrane keyboard.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_Watrex_SPR_200_Solvent_saver_I_Nputs_694d991f2c.jpg" alt="Watrex: Watrex SPR-200 Solvent saver - INputs">The SPR-220™ Solvent Recycler continuously monitors the output signal of the chromatography detector and displays its current value on the built-in display. A highresolution analog-to-digital converter provides data for further evaluation in the built-in processor. If the input signal level exceeds a preset value (Threshold), the SPR-200 will redirect the flow to the waste.When the signal drops, the solvent recycler waits for the transport delay and then switches the mobile phase back to the reservoir. An autosampler injection marker connected to the SPR-200 ZERO input can be used to zero the input signal at the time of injection.<h3>FEATURES</h3><ul><li>Stand alone operation</li><li>Detachable valve</li><li>Possibility of manual Waste/Recycle switching</li></ul><h3>TECHNICAL SPECIFICATION</h3><ul><li>Detector compatibility: compatible with any HPLC detector</li><li>Connection: 1/16″ O.D. tubing, 1/4″-28 flat bottom fittings</li><li>Maximum pressure: 30 p.s.i./0,2 MPa</li><li>Wetted material: PEEK, PTFE</li><li>Input range: +/- 1 V or +/- 100 mV, user selectable</li><li>Computer connection: μUSB</li><li>TTL/contact closure input: configurable (ZERO, start, valve position)</li><li>Power: 5V DC/&lt;100 mA (power supply or computer USB port)</li><li>User interface: large character LCD alphanumeric display + membrane keypad</li></ul><h3>Ordering information:</h3><h5>PN/Component:</h5><ul><li>SPR200-001 SPR-200 Solvent Recycler, PEEK version (Price 1 250 € ex VAT)</li><li>SPR200-002 SPR-200 Solvent Recycler, PTFE version (Price 1 250 € ex VAT)</li></ul>You can also visit this product on the <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/?s=SPR-200+Solvent&amp;post_type=product&amp;dgwt_wcas=1?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">Watrex website</a>.

Watrex LSS-205 Liquid Sensing System

Liquid Sensing System LSS-205 is a universal sensing system for monitoring the level of your chromatographic system liquids.

Universal sensing system for monitoring the level of your chromatographic system liquids. The daily task in the chromatographic laboratory is the manipulation of mobil phases. The operator must check the supply of solvents at the inlet of the device and regular monitor the condition of the waste solvent container. The LSS-205 greatly simplifies these tasks.<blockquote>Price: 578<bdi>&nbsp;€ ex VAT</bdi></blockquote>LSS-205 is a universal accessory for any (chromatographic) system. The level sensors used in the LSS-205 system are contactless, do not require immersion in liquid, and are installed on the outer shell of a non-metallic solvent container. The method of mounting the sensor allows placement on a container of virtually any shape and size.The LSS-205 central unit is ready to process the signal from up to five liquid sensors, which can be individually set to trigger an alarm in the event of a missing or present liquid. The error status of the individual sensors is indicated optically directly on the central unit and the alarm can be accompanied by an acoustic signal. An external loud siren suitable for a noisy environment is available as an option to the central unit.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_LSS_205_Liquid_Sensing_System_33_0fd5d29a02/Watrex-LSS-205-Liquid-Sensing-System-33.jpg" alt="Watrex LSS-205 Liquid Sensing System"><h3>FEATURES</h3><ul><li>Simple operation</li><li>Flexible in application</li><li>Multiple connection option</li><li>Starter kit contents: central unit, one sensor, light bar, power supply</li><li>Color touch panel control</li></ul><h3>TECHNICAL SPECIFICATION</h3><ul><li>Power supply: 5V DC (wall mount power supply or USB port of PC)</li><li>Number of liquid sensors: 1 – 5</li><li>Alarm condition: individually adjustable for each sensor (off, missing liquid, liquid present)</li><li>Internal alarm indication: high intensity LED for each sensor</li><li>Internal acoustic alarm: 80dB, common for all sensors</li><li>External optical signaling: connector on the central unit</li><li>External acoustic alarm: optional 105 dB external horn</li><li>Alarm signal for external devices: logic (open collector), relay switching contact</li><li>Computer connection: micro USB connector, simple text communication protocol</li><li>Firmware update: possible in field</li><li>Dimension: 130x80x30 mm</li><li>Weight: 250 g</li><li>Sensor dimensions: 50x30x15 mm</li><li>Sensor connection cable: 2 m length</li><li>Sensor mounting: plastic holder with flexible silicon tube (length 700 mm, other lengths on request)</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Watrex_LSS_205_Liquid_Sensing_System_6_7b35aadbb7/Watrex-LSS-205-Liquid-Sensing-System-6.jpg" alt="Watrex LSS-205 Liquid Sensing System - level sensor"><h3>Ordering information:</h3><h5>PN/Component:</h5><ul><li>40-0728 Starter Kit (incl. 1 sensor + light)</li><li>40-0738 LSS-205 Additional Sensor</li><li>40-0841 LSS-205 Additional 2 Sensors</li><li>40-0842 LSS-205 Additional 3 Sensors</li><li>40-0843 LSS-205 Additional 4 Sensors</li><li>40-0838 LSS-205 External Alarm Horn</li></ul>You can also visit this product on the <a target="_blank" rel="noopener noreferrer" href="https://watrex.com/obchod/chromatography/dedicated-instruments/lss-205-starter-kit/?utm_source=labrulez&amp;utm_medium=propagace&amp;utm_campaign=labrulez_produkty">Watrex website</a>.
