Description:

Wide neck 300ml tough conical flask made from heat and smash resistant borosilicate glass (similar to Pyrex). These flasks are often used by bars to serve mixers for adding to cocktails etc. They have a flared neck for easy pouring.
Conical flasks are laboratory glassware that is designed so that the liquid contents can be swirled or stirred without spilling. The narrow neck also reduces the loss of evaporating contents.
These flasks can be heated - but please avoid flames touching the glass by using a fine wire gauze between the heat source and the glass.

    Microwave safe:

  • Remove all fittings such as plastic caps - which may not be microwave proof.

    About Borosilicate Glassware:
    Borosilicate glass has a low thermal expansion coefficient and high chemical resistance, making it ideal for use in laboratories and the medical and pharmaceutical industries. All the boroscilate glass on our website is Type 3.3 borosilicate glass. Type 3.3 is named because of the coefficient of expansion for borosilicate glass is 3.3x10-6K-1 (20 - 300C).

    Caring for Borosilicate glassware.
    Please follow these rules to ensure safety and long life of your borosilicate laboratory glassware:
  • Schedule regular examinations of glassware
  • Do not use any glassware which is scratched, chipped or cracked. Defects like these can seriously weaken the glass and make it prone to breakage in use.
  • Never soak glassware for long periods in very strong alkaline solutions as it will damage the glass.
  • Ultrasonic cleaning is a good method of cleaning glassware thoroughly. Using an ultrasonic cleaner with a mild detergent will clean most residues from the glassware.
  • Borosilicate glass is completely microwave safe. However, as with any microwave vessel, be sure it contains a microwave absorbing material such as water before placing in the oven. Also remember to remove fittings such as plastic caps which may not necessarily be microwave proof
  • Always provide adequate support to glassware at the base.
  • Do not lift, carry or suspend glassware by the neck, rim or side arms.
  • Hydrofluoric acid, hot concentrated phosphoric acid and very strong alkalis attack and weaken borosilicate glassware.
  • The maximum recommended working temperature for borosilicate glassware is 500C (for short periods only). However, once the temperature exceeds 150C extra special care should be taken to ensure that heating and cooling is achieved in a slow and uniform manner.
  • Heat vessels gently and gradually to avoid breakage by thermal shock. Similarly, allow hot glassware to cool gradually and in a location away from cold draughts.
  • If using a Bunsen burner with borosilicate glassware employ a soft flame and use wire gauze with ceramic centre to diffuse the flame.
  • Do not directly heat glassware on a hotplate as this can create hot spots on the glassware which may cause the glassware to shatter.
  • Flat bottomed vessels should never be used under vacuum. The only exceptions are those products designed specifically for that purpose
