 Thermolyne Cellgro 45600 S45625 Multi 5-point Magnetic Stirrer. The company is also known as Barnstead/Thermolyne. Good working condition.  The front speed control knob functions.  The change in sound of the motor inside when rotating the knob in either direction indicates that the speed control does vary the speed.  We do not have the equipment to verify the actual RPM range but we did test this unit (and others we are selling) using the very scientific method of filling a styrofoam cup with water, dropping a paper clip in it, and then watching the paper clip revolve at different speeds depending on which direction, and how far, the speed control knob was rotated. See photo of bottom.  Lab equipment in our experience is sometimes rusty or stained on the bottom, showing it was not well taken care of and/or people were careless about cleaning it in the event of a spill.  The bottom of this item and the two other higher-end (but same size and number of stirring stations; same brand) stirrers we have recently listed show no signs of this. DISCLAIMER:  We perform a general cleaning of items like this to remove dust, dirt and the like.  We do not claim to sterilize equipment we sell, nor to eliminate or even reduce any bacteriological, virulogical, or other possible contaminant or pathogen levels.  We have no information from the sources of lab equipment that we sell to suggest that there is any specific reason to be concerned (e.g., that it came from an environment in which live serious disease organisms were being cultured), but you should use common sense in handling used equipment of this type. As with any used lab equipment, please take whatever steps you determine, after appropriate research, hiring consultants, etc. that is appropriate within your industry to safeguard you and those whom you permit to handle this equipment. Runs on 120V, 50/60Hz All 5 positions rotate at the same speed. Components are rated for temperatures from -20 to +60°C (-4 to +140°F); excellent for incubator work. Five stirring positions Dimensions: 15 x 15 in. Stirring range up 100 RPM Most of these sold recently for between $100 and $200 each. Note that items like this when new may come with a "stirrer" that often looks like a medicine capsule, which is designed in a way to not stick to the bottom of the container you place on the stirrer to be stirred.  Without an item like this, no stirring will actually happen with whatever you might place on this device.  We do not have any of these so they are not included, but items like that are not proprietary (one of us has seen them sold in "blister packs") and are we are sure readily available from a variety of sources. The serial number on this unit is 456991086145.  We have two same size more advanced units (with digital speed display, and interval setting dial) current listed, with the same 5-top-position design as the unit featured here. SHIPPING:  FREE to the 48 continental United States via our choice of shipping at ebay's "Economy" class (meaning can take up to 9 business days, once shipped, to arrive).  If you need this faster, contact us for a quote.  We generally ship only via FedEx Ground or FedEx Express services. RETURNS:  14 day return, allowed if this unit arrives either non functioning, or fails to remain functional during that time period, so long as there are no obvious signs of user abuse (e.g., fluid found inside the case; top cracked; sides dented; etc.).
Condition Used :
An item that has been used previously. The item may have some signs of cosmetic wear, but is fully operational and functions as intended. This item may be a floor model or store return that has been used. See the seller’s listing for full details and description of any imperfections.
Seller Notes This item has the typical set of minor scuffs and scratches typical of an item that was used in a research laboratory as this one was. Think of a kitchen appliance you used every day for a year or more and you'll have a decent idea. Nothing that would make a venture capitalist withdraw an offer of funding due to a loss of confidence in staff on seeing the lab you'll be installing this in.
