Thanks for the tips Sheila and Stanley. I am not sure if we will go with gravity dispensing. I will look into those products mentioned. I appreciate the information given.

We have unfortunately had mixed experiences with the Goat Throat pumps about 1-2 years ago. While we worked with Nancy to ensure that the seals were tested for resilience against the intended solvents, we saw signs of degradation of the polymer dip-tubes and pump-head casing for most solvents tested within the initial 30-day pilot. A few of the labs began complaining about potential contamination of their solvents which prompted a quick abort of the pilot.

Switching to a stainless steel dip-tube would help with the worst of this problem, but the underside of the pump-head (which is exposed to the container headspace) similarly showed signs of degradation which made us weary about the long-term prospects of these pumps.

We are currently exploring the B=C3=BCrkle line of solvent pumps, which offer a more traditional stainless-steel body (for resilience and easy B/G) and closable ball-valves which help to keep the vapors in check when not in use (which was a significant selling point for us when first considering the Goat-Throat). These are now carried by VWR which mak

We don't particularly encourage gravity dispensing from the 5-gal containers, but when that is preferred, we encourage the use of the tilt stands (such as the Morse PailPro, Vestil Pail Tipper, Champ 2259 or Justrite 11273) to help remove some of the ergonomic issue and help make sure that these containers are not stored horizontally (when used with a safety faucet).

The only pump we have found for 5-gallon (20-L) cans that doesn't leak is the GoatThroat pump (GoatThroat.com).

Subject: [DCHAS-L] bulk solvent storage room information

Hello,

We are in the process of renovating a bulk solvent storage room in our Chemistry building. We will be dispensing from 5 gallon containers. We previously dispensed from 55 gallon drums. We are in the design phase for shelves, racks and dispensing systems and want to maximize storage space while finding the best dispensing tools to help minimize spills. Our stockroom has priced square and round 5 gallon containers and we are now looking into dispensing racks and tools..

If you currently dispense solvents from 5 gallon containers then I am looking for your insight on what set up you have in place and what works best for you (or what did not work well). Suggestions on products you use such as rotating dispensing racks for gravity dispensing would be great.

Thank you,
