Product Name: Boro 3.3 Glass Beaker
Product Type: 5–2000ml
Product Material: High borosilicate glass
Product Introduction:
High borosilicate glass has a very low coefficient of thermal expansion, about one-third that of ordinary glass. It can withstand high temperatures of 200 ℃ temperature difference, low expansion rate, high strength, high chemical stability. The laboratory sterilization temperature standard is 121°C/134°C, and the bottle cap can withstand up to 140°C high temperature.
It can serve as a material reactor, determine combustion products, be used to dissolve and crystallize a substance, hold solutions for evaporation, concentration, or heating, and also be used to hold corrosive solid chemicals for weighing.

Precautions For Use
- Do not inject more than half of its capacity; too much can easily cause splashing.
- When heating a beaker, place a wire gauze underneath to distribute the heat evenly.
- Do not use products that are corroded, cracked, chipped, or scratched.
- When heating, the outside of the beaker must be wiped dry.
Frequently Asked Questions (FAQ)
Q:
What are the main characteristics of high borosilicate glass used in these beakers?
High borosilicate glass features a very low coefficient of thermal expansion (about one-third of ordinary glass). It offers high strength, high chemical stability, and can withstand a temperature difference of up to 200°C.
Q:
What sterilization temperatures can the Boro 3.3 glass beakers and caps withstand?
The standard laboratory sterilization temperature for the glass body is 121°C/134°C, while the matching cap can safely withstand high temperatures up to 140°C.
Q:
What are the typical laboratory applications for these glass beakers?
They are commonly used as material reactors, for determining combustion products, dissolving and crystallizing substances, holding solutions for evaporation, concentration, or heating, and weighing corrosive solid chemicals.
Q:
Why is a wire gauze necessary when heating a glass beaker?
A wire gauze should always be placed underneath the beaker during heating to distribute heat evenly across the flat bottom, preventing localized thermal stress and potential shattering.
Q:
How much liquid should be filled in the beaker during operation?
It is recommended not to inject more than half of the beaker's capacity to prevent boiling over or splashing during heating and mixing operations.
Q:
Can I still use a glass beaker if it has minor scratches or chips?
No. For safety reasons, you must never use laboratory glassware that is corroded, cracked, chipped, or scratched, as these defects compromise structural integrity under thermal stress.
