Funnels are available for purchase at eChemShop

Are made strongerFunnel with temperature retained jacket / 10ml / 21mm DIA TS15/25

Roth cup portion integral molding. Has uniformity at the top.

Easy to clean

If you have a number of holes like a Buchner funnel, and build up this "purse" would be able to part. This is very difficult to wash the internal, invisible while. Kiriyama funnel hole in the center is the one place. Easy cleaning done with a simple structure and internal visibility.

You can connect directly with transparent sliding fit into the suction bell and suction flaskNeck size: TS15/25

Kiriyama funnel transparent sliding all together (for each type of VB SB SU SC) by suction bell, etc. Please use a combination of suction flask. All types are available for the S type rubber stopper. 

The heat-resistant glass
HARIO H Kiriyama funnel is proven in the heat-resistant glass-made of 32.
And excellent heat resistance, coefficient of linear expansion (0 ~ 300 ?) and the expansion 32,0 ? 10-7 / ?, the shrinkage is small, is resistant to heat. Also suitable for filtration GFF glass fiber filter paper using heat. The main component silicon dioxide (80 percent) is less stable chemical properties of extremely alkaline elution.


Tough and DurableNeck: Rubber stopper type

A cup part of Kiriyama-rohto is molded in one shot by glass press.
So it has durable, strong, uniform quality.

Easy to wash

Buechner funnel has many holes leads to a drain part whose inside is hard to be seen and washed.
Kiriyama-rohto has only one hole at the center. Because its structure is simple and the inside of it is visible, it can be washed easily.

Direct connection to Bell Jar and Vacuum Flask

Kiriyama-rohto can be connected directly to a bell jar / vacuum flask by grounded glass surface (VB / SB / SU / SC types).
Rubber stopper connection type (S type) is also available.

Made from heat-resistant glass

Kiriyama-rohto is made from well reputed heat-resistant glass, HARIO H-32.
This material has excellent heat-resistant feature because of its small coefficient of the expansion and contraction that is (0-300 ?) 32,0 x 10-7 / ?
It is suitable for high temperature filtration with a glass fiber filter (GFP serious).
Also it is chemically stable and has low alkaline elution because its 80% of the component is silicon dioxide.
