Question/Answer
Can I autoclave the glass filter base with the rubber stopper attached without destroying the stopper?
The stopper is made out of silicone rubber and is autoclave safe.
Are these funnels/bases magnetic? or is a clamp needed?
These funnels have a screw on attachment.
when using this funnel/base, is part of the outer perimeter of the filter covered by the funnel? or Is the entire surface area of the filter usable?
Part of the filter is sandwiched between the funnel and base. This ensures that the edges of the filter are sealed and none of the liquid to be filtered escapes around the filter.
do you have these in 100ml volumes?
No, they are only available in 300 mL sizes.
May I use agar to pour over the membrane and is there a lid to the peri dish? Is the cost $141 for 48?
An instruction sheet link has been added to this web page showing exactly how the media addition is handled using this product. After filtration of the sample an aliquot of media is added to the filter and pulled through to the supporting pad underneath. This provides the growth media for the bacteria. Yes--a lid to the petri dish is provided (it is the same lid used on the funnel). Current pricing is on the website.
