The system targets applications requiring pyrogen-free, nuclease-free water.\u003c\/p\u003e\n\u003ch3\u003eWhat voltage and power does the WB311UFB require?\u003c\/h3\u003e\u003cp\u003eThe WB311UFB operates on 220V \/ 50 Hz. Confirm your facility provides a matching circuit before installation.\u003c\/p\u003e\n\u003ch3\u003eWhat are the unit dimensions and weight?\u003c\/h3\u003e\u003cp\u003eUnit dimensions are 21.6\" × 14.7\" × 14.4\" (54.8 × 37 × 36.5 cm). Shipping weight is 35.1 lbs, and the system mounts on a benchtop or wall.\u003c\/p\u003e\n\u003ch3\u003eHow does the system achieve pyrogen-free, nuclease-free water?\u003c\/h3\u003e\u003cp\u003eAn ultrafiltration module works with conditioning and polishing cartridges and a 0.2 micron final filter. This combination removes pyrogens and delivers nuclease-free output.\u003c\/p\u003e\n\u003ch3\u003eWhat is the typical flow rate and feed water requirement?\u003c\/h3\u003e\u003cp\u003eTypical flow rate is 2.5 LPM (0.67 GPM). Feed water should measure below 20 µS\/cm to maintain rated performance.\u003c\/p\u003e\n\u003ch3\u003eDoes the WB311UFB include a TOC monitor?\u003c\/h3\u003e\u003cp\u003eNo, a TOC monitor is not included. The system does provide real-time water-quality monitoring with integrated leak detection.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@graph\": [\n    {\n      \"@type\": \"Product\",\n      \"@id\": \"https:\/\/labsupplies.com\/products\/benchtop-with-ultrafiltration-module-50hz-wb-311ufb#product\",\n      \"name\": \"Yamato WB311UFB Benchtop - With Ultrafiltration Module, \/50Hz\",\n      \"sku\": \"WB-311UFB\",\n      \"mpn\": \"WB-311UFB\",\n      \"brand\": {\n        \"@type\": \"Brand\",\n        \"name\": \"Yamato Scientific\"\n      },\n      \"manufacturer\": {\n        \"@type\": \"Organization\",\n        \"name\": \"Yamato Scientific\"\n      },\n      \"url\": \"https:\/\/labsupplies.com\/products\/benchtop-with-ultrafiltration-module-50hz-wb-311ufb\",\n      \"dateModified\": \"2026-06-29\",\n      \"offers\": {\n        \"@type\": \"Offer\",\n        \"priceCurrency\": \"USD\",\n        \"price\": \"12820.00\",\n        \"availability\": \"https:\/\/schema.org\/InStock\",\n        \"url\": \"https:\/\/labsupplies.com\/products\/benchtop-with-ultrafiltration-module-50hz-wb-311ufb\",\n        \"seller\": {\n          \"@type\": \"Organization\",\n          \"name\": \"LabSupplies.com\"\n        }\n      },\n      \"gtin12\": \"797059929399\",\n      \"image\": \"https:\/\/dl.dropboxusercontent.com\/scl\/fo\/02jn6wbbh1yhzaqkcyplw\/h\/WB301.png?rlkey=wtjo5lqeg5sku9a3506qrpssx\",\n      \"description\": \"Yamato WB311UFB Type I ultrapure water system: 18.2 MΩ·cm, ultrafiltration, 2.5 LPM, 220V.
