Volumetric (Measuring) Flasks

under the product series “AGN”, compliant with Class ‘B’ of I.S. 915:2012, which is the Indian Standard for volumetric laboratory glassware. Here’s a clear tabular summary of the product information for easier reference:

1181/1	*1	0.02	10/15	2	Test tube shape
1181/2	*2	0.03	10/15	2	Test tube shape
1181/3	5	0.05	10/15	2
1181/4	10	0.05	10/15	2
1181/5	20	0.05	10/15	2
1181/5a	25	0.08	10/15	2
1181/6	50	0.12	10/15	2
1181/7	100	0.20	14/15	2
1181/8	200	0.30	14/15	2
1181/9	250	0.30	14/15	2
1181/10	500	0.50	19/20	2
1181/11	1000	0.60	19/20	2
1181/12	2000	1.20	24/25	2

Notes: Class B flasks have lower accuracy than Class A but are suitable for general-purpose volumetric measurements. Interchangeable stoppers suggest these flasks come with ground-glass joints.
