Condition: used, This listing is for 1 of 7 Watson Marlow 620S/R Peristaltic Pumps The units are in full working condition and ready for immediate use Design & Functionality The 620S/R model is part of the 600 Series of cased peristaltic pumps featuring a brushless DC motor equipped with digital keypad control (620S) and a sturdy NEMA 2 / IP31 vented, wipe‑down enclosure suited for dry industrial environments ,It operates at dual voltage (100–120 V or 200–240 V, 50/60 Hz) and includes features like MemoDose for one-shot dosing and wireless guard-switching for safety The casing is chemically resistant, with powder-coated die-cast aluminium construction and an easy-to-clean membrane keypad Pump Performance Flow range: 0.00026 to ~4.23 gpm (equivalent to ~0.001 to 16 L/min) with the 620R pump head With newer 620RE LoadSure heads, the flow increases up to ~4.76 gpm (0.004–18 L/min) Pressure capability: Up to approximately 60 psi (4 bar) with the appropriate head and tubing Djdjxhdx Dopfx Adascp Control accuracy: Exceptional 2,650:1 turndown ratio, fine speed control from 0.1 to 265 rpm in selectable increments (0.1, 0.5, 1, 2, 5, or 10 rpm), with 0.1% speed accuracy Pump Heads & Tubing The model supports the following interchangeable pump heads: 620R Mk II (continuous tubing, two rollers) 620RE and 620RE4 (LoadSure elements, two or four rollers) These heads are compatible with various tubing materials (e.g., Marprene™, Bioprene™, Sta‑Pure™, silicone) and sizes (typically 6.4 mm to 17 mm inner diameter) The 620RE and RE4 heads feature retractable rollers for easier cleaning (CIP/SIP) and rapid loading AFAB Lab Resources - Used Lab Equipment Physical Attributes & Construction Ingress Protection: IP31 (NEMA 2) for the standard 620S/R; there are IP66/NEMA 4X variants (e.g., 620SN/R) for environments requiring better dust and water resistance Weight: Around 19.6 kg (with 620R/RE head) to 20.1 kg (with 620RE4) Sound level: Less than 70 dB(A) at 1 m—relatively quiet for continuous industrial operation Advanced Features MemoDose: Delivers precise single-shot volumes—ideal for dosing applications Ramp function & non‑drip: Ramp improves handling of delicate fluids, preventing splashes/frothing, while non-drip minimizes residual drips at dose end (noted in related Di versions but often included in feature suites) Data export: Some models (e.g. 620S/RE) support RS‑232 export of batch records—important for GMP compliance

Condition: used, This listing is for the Watson Marlow 323 Peristaltic Peristaltic Pump The unit is in full working condition and is ready for immediate use The 323 series from Watson‑Marlow is a benchtop “cased” pump line (sometimes called peristaltic or rotary tubing based pumps) designed largely for laboratory and light industrial applications. Key features include: A drive unit (“drive”) plus interchangeable pumphead/tubing to suit different flow rates, tubing types, chemical compatibilities. Versions available with different levels of control: manual speed control; auto/remote control; analogue inputs/outputs; RS‑232 etc. A membrane keypad and digital LCD on most models to set/display speed etc. Build is robust: chemically resistant ABS top, IP31 protection rating Dodpexhdu Eofx Adascp

Condition: used, This listing is for the Autoclude Model V Peristaltic Pump The unit is in full working condition and is ready for immediate use The Autoclude peristaltic pump is a type of tube (hose) pump made by Verderflex / Autoclude. Its defining feature is that only the flexible tube (or hose) inside the pump is in contact with the fluid being pumped. The rest of the pump (rollers, casing etc.) stay clean / isolated. This makes them good for contamination-critical, corrosive, slurry, or shear-sensitive fluids Dcjdexhduxopfx Adaop Design / Key Features Some of the design / functional features: Seal-less and valveless: Since fluid is contained within tube, no seals exposed to fluid or valves that could leak. Self-priming: Can start pumping without needing fluid completely filling the inlet, and often able to handle gas or ‘air’ in the line. Capable of running dry without damage (when tube material allows) for short durations. Electrolab Group Reversible flow: The rotor or drive can reverse, so flow can be reversed to purge lines, etc. Gentle pumping: Because fluid only contacts tube, and the shearing is limited, better for shear-sensitive liquids / slurries. Rapid tube replacement Stackable / multi‑head options: Some “easy tube loading” models allow several pump heads to be driven by a single drive unit, for multi‑channel or sampling/analysis setups

Condition: used, This listing is for 1 of 3 Watson Marlow 630S Peristaltic Pumps These units are in full working condition and ready for immediate use Dsdpfx Adsxhdtbjascp A peristaltic pump moves fluid through a flexible tube by sequentially compressing the tube (like a wave) which pushes the fluid forward. Because only the inner surface of the tube contacts the fluid, the pump mechanism is isolated from the fluid — this is useful for: Handling corrosive, abrasive or sterile fluids Avoiding contamination (the pump body doesn’t contact the fluid) Easy maintenance (replace the tubing rather than the pump’s internal components) Watson‑Marlow is a well-known maker of such pumps in lab, process, pharmaceutical, chemical, water treatment, and industrial settings. Typical applications / use cases Because of the flexibility, purity, and control of peristaltic pumps, the 630S is used in: Chemical dosing / metering (acid, base, reagents) Pharmaceutical / biotech processes Water / wastewater treatment Food & beverage (for sterile or food-contact fluids) Laboratory and pilot-scale processing
