This British Standard specifies requirements for a limited range of two types of glass centrifuge tubes for general laboratory use.
The two types specified are:
- graduated or ungraduated glass centrifuge tubes with a rounded bottom;
- graduated or ungraduated glass centrifuge tubes with a conical bottom.
NOTE 1 The two types are shown in Figure 1.
The nominal volumes covered are 6 mL, 9 mL, 13 mL, 25 mL and 40 mL (see clause 3).
NOTE 2 The nominal volumes indicated are those representative of the actual volume below the fill line. Traditionally these were referred to as 5 mL, 10 mL, 15 mL, 25 mL and 50 mL.
The glass centrifuge tubes specified in this British Standard are suitable for use with solutions of apparent density up to 1.2 g/mL at 20 °C and are designed to withstand the forces due to an acceleration of 35 000 m/s2.
NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
