Borosilicate Beaker (133mm ID) for 16 Place Quartz Parting Basket (QBL16)

Description

Borosilicate beaker BBW-36 for the cupellation parting process with nitric acid according to ISO11426

Dimensions of the beaker are: 133mm ID x 100mm IH

(beaker is specially designed to fit the quartz parting and annelling basket QBL16)

Main characteristics of the beaker are:

Withstands concentrated / boiling nitric acid attack.
Low thermal expansion coefficient (αL = 3.3·10-6·K-1). Three times less linear expansion than ordinary glass.
Low density and low thermal mass (Specific heat capacity 0.83 J / g·K)
Resists temperatures up to 500ºC
Softening point 820º C
Thermal shock: Resists temperature differentials of up to 165ºC
(Ordinary glass resists temperature differential of only 37ºC)
