Description

Kontes® DUALL® Tissue Grinder
50 mL (Size Code 25)
General Description
One unused, top-quality unit, manufactured by Kontes®. The mortar is all glass and has beaded rim with pour spout. The pestle is PTFE with a metal handle. This is a huge grinder - the largest in the series, with a 50 mL working capacity.
The combination of cylindrical and conical surfaces creates a more efficient and effective grinder.
Since the mortar is glass, it was briefly removed from the box to verify the quality of the contents
. The pestle is still sealed onto cardboard tray (there is hole in the wrap behind the top of the handle created by the sharp metal edge, however it is not large enough for the pestle head to pass through).
"Combines both conical and cylindrical surfaces to effectively reduce tissue and produce a uniform homogenate.

Combined Shipping:
When quantities greater than one are entered into a listing's shipping calculator, it will likely display a shipping charge that is higher than what will actually be charged. This overage may also appear during checkout with purchases of more than one item of the same item number, as well as multiple item number orders, if payment is made before an invoice is emailed. This happens because the system adds all the weights and packaging fees together. It cannot account for all the variables involved in multiple item orders.
When two or more of any item is purchased, even if they are all the same item, please request or wait for an invoice for your purchases.
Note that with all orders, there is no 'handling charge' - the shipping charge is only composed of our cost in freight, insurance (if applicable) and packaging materials. Please feel free to request a quotation for any combined shipping costs, be sure to include your zip code. An invoice will be delivered more quickly if the 'request total from seller' link is used. When two or more of any item is purchased, even if they are all the same item, please request or wait for an invoice for your purchases.
