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 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. Knedpfoxhduxjx Ag Noc 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 the Hitech Instruments GIR250 Gas Analyser The unit is in full working condition and is ready for immediate use The GIR250 is a bench‑top / transportable analyser designed to measure oxygen (O₂) and carbon dioxide (CO₂) simultaneously in gas samples. Knsdpoxhdqtefx Ag Njc It is made by Hitech Instruments (now part of the MTL / Eaton group). Its design emphasizes ease of use, reliability, and low maintenance cost. Other supporting features: The instrument can be programmed with pass/fail criteria for each gas (alarms). It provides analog outputs, typically 4–20 mA, for external logging or control systems. Calibration is designed to be simple (via the front panel keypad) to reduce training burden. The O₂ galvanic cell is user-replaceable (i.e. maintenance can be performed in the field). Mechanical, Electrical & Operational Details The GIR250 is housed in a rugged, transportable case (lab-style) so it can be used as a benchtop or mobile analyser. Sample inlet and outlet connections use 0.25″ (~6 mm) tubing. The sample system should avoid condensation and contaminants; non‑condensing sample environment is required. Operating ambient temperature: –5 to +40 °C (for non‑condensing conditions) Power / interface: standard for bench‑top analysers (the catalogue doesn’t always detail it, but likely mains or DC supply, suitable for lab use) Typical Applications & Suitability Because it can measure both O₂ and CO₂ in a single unit, the GIR250 is used in applications such as: Respiration / breathing gas analysis / Douglas bag analysis (i.e. in physiological or experimental gas mixture measurement) Fermentation / bioprocess monitoring (where O₂ and CO₂ both matter) Gas mixture / inertisation / process gas quality (checking gas purity, calibrating mixtures) It is not primarily intended for measuring very low trace levels (ppm-level) of O₂ or CO₂ unless its ranges are suitably adapted or specified. The design is more for percent-range analysis

Condition: used, This listing is for the Watson Marlow 620 Du/R Peristaltic pump The unit is in full working condition and is ready for immediate use The 620DU is a process peristaltic pump (i.e. hose pump) designed for metering, dosing, and transfer of fluids. Because it is a peristaltic design, the fluid is contained entirely within the tubing, avoiding contact with internal moving parts (other than the tubing). It is suitable for remote control, automation, and integration into control systems (SCADA, factory logic, etc.). Wide control range & precision: The large turndown (2,650:1) gives flexibility to handle both very low and high flow rates with fine control. Knjdpfx Agoxhdt Is Nsc Remote / automation capabilities: Because it supports analog and digital interfaces, it’s well-suited for integrated systems. Pump protection & security: PIN locking helps avoid unintentional changes in process-critical applications. Low maintenance on non‑wetted parts: Since only the tubing contacts fluid, mechanical wear is mostly on the tubing, making part replacement simpler. Safe to run dry: Peristaltic pumps typically tolerate running dry without damage (unlike many positive displacement pumps). Reversible / ability to back‑flush: This is helpful when attempting to clear lines or avoid clogging. Limitations / Considerations Tubing wear / life: The hose or tubing is the consumable component. Chemical compatibility, pressure, and mechanical stress affect how often tubing needs replacement. Upper pressure / flow limit: While it handles decent pressure (~2 bar standard, possibly up to 4 bar variant), it’s not suited for very high-pressure pumping tasks. Enclosure limitations (non-“N” model): The standard 620DU is not fully sealed, so it may not be ideal for wet or harsh environments unless you use the “N” variant. Cost / complexity: More features, interfaces, and protection can make the system more complex (and costlier) to configure, install, and maintain.
