This borosilicate glass is pear shaped boiling flask and has a short neck and interchangeable joint. The socket size is 19/26.

Lubricate the ground surfaces of glass joints to prevent leakage in use and facilitate separation. Use a silicone-free laboratory grease and apply a light coat completely around the upper part of the joint. This will protect the joints and keep your glassware good for longer. The glassware is highly resistant to water, neutral and acid solutions, concentrated acids, chlorine, bromine iodine, and organic matters.

 It can withstand repeated dry and wet sterilisation without surface deterioration and subsequent contamination. All glassware is annealed under strictly controlled conditions to ensure minimal residual stress in the products. The temperature gradient are consequently low, the coefficient of thermal expansion is low, and the glass can withstand higher temperature gradients and also sudden temperature changes/thermal shocks.

 General precautions when using any type of glassware:
Take time to examine the glassware to ensure that is in good condition.
Never use scratched, chipped or cracked glassware.
Wash glassware promptly after use to avoid hard dried residues.
Do not use cleaning brushes which are badly worn and where the metal spine may scratch the glass.
 
Each product is carefully designed by a team of laboratory professionals and experienced engineers with quality and durability in mind. They are manufactured with only the highest grade, raw materials and according to international quality standards to ensure that they can withstand use in even the toughest laboratory environments.
