24、aboratory glassware Bottles Part 1: Screw-neck bottles1 ScopeThis part of ISO 4796 specifies a series of screw-neck bottles suitable for the storage of fluid liquid and solid chemicals and reagents in general laboratory use. These bottles with nominal volumes ranging from 25 ml to 20 000 ml are also
25、 suitable for the preparation and storage of microbiological growth media.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated refer
26、ences, the latest edition of the referenced document (including any amendments) applies.ISO 3585, Borosilicate glass 3.3 Properties3 Capacities3.1 The nominal capacities of screw-neck bottles shall be chosen from the following series: 25 ml 50 ml 100 ml 150 ml 250 ml 500 ml and 750 ml; 1 l 2 l 3,5 l
27、 5 l 10 l 15 l and 20 l.3.2 The nominal capacity of a bottle indicates the quantity of liquid which a bottle of average wall thickness shall contain when the bottle is filled to the turn of the shoulder.3.3 The design of the bottle shall be such that the total capacity to the base of the neck shall
28、be approximately 15 % greater than that to the shoulder.4 DimensionsThe dimensions and tolerances of screw-neck bottles are given in Figure 1, Figure 2, and Table 1.Table 1 DimensionsNominal capacityTotal height h1Height to shoulder h2Outside diameter d1Wall thickness sInternal neck diameter d2ml mm

32、ear, colourless or amber borosilicate glass 3.3 in accordance with ISO 3585.5.1.2 Internal stress and visible defects in the glass (such as bubbles near the surface) shall be reduced to a level sufficient to minimize the possibility of fracture due to thermal or mechanical shock.5.2 Design5.2.1 The
33、base of the bottle shall be constructed so as to enable the bottle to stand firmly on a flat surface without rocking or spinning.5.2.2 The base of the bottle shall have a suitable radius so as to provide a smooth transition between the base and the side. The main portion of the side shall be cylindr
34、ical for bottles with nominal capacities of 25 ml to 2 000 ml, and slightly tapered for bottles with nominal capacities 3,5 l to 20 l with the smaller diameter at the base of the bottle.The diameters d1shall be as given in Table 1.5.2.3 The shoulder of the bottle shall have a suitable radius in orde
35、r to provide a smooth transition between the side and the conical upper proportion of the bottle. ISO 2016 All rights reserved 3BS EN ISO 4796-1:2016ISO 4796-1:2016(E)5.2.4 The upper portion of the shoulder shall be of conical shape. The transition radius from the shoulder to the neck shall be as sm
36、all as possible to be compatible with manufacturing practice.5.2.5 The bottle shall be blown so as to evenly distribute the glass in the mould avoiding sudden changes in the wall thickness. The thinnest areas shall not have a thickness less than the minimum value specified in Table 1.5.2.6 The neck
37、of the bottle shall be stoutly constructed and finished with a strengthening lip designed to facilitate pouring without liquid running down the outside of the bottle. A clip-on anti-trip ring of plastics material fitting into a slightly recessed channel on the outside of the neck is a permitted alte
38、rnative form of construction.NOTE There are suitable national standards for the dimensions and design of the thread of the screw neck.5.2.7 The outer glass surface of the bottles may be coated with a suitable plastics material as a protection and to limit leakage of liquid if the bottle is damaged.
39、The coating shall be resistant to steam sterilization at 135 C.5.3 ClosuresBottles shall be provided with closures of a suitable inert plastics material, e.g. polypropylene. Closures shall form a liquid-tight seal with the threaded bottle neck.6 DesignationIf a designation of bottles is required, th
40、is shall be by reference to this part of ISO 4796, i.e. ISO 4796-1, together with the nominal capacity of the bottle.EXAMPLE For a bottle with a nominal capacity of 500 ml, the designation would be as follows:Laboratory bottle ISO 4796-1 5007 Marking7.1 Bottles complying with this part of ISO 4796 s
41、hall be marked with the following:a) nominal capacity;b) makers and/or vendors name and/or trade mark;c) number of this International Standard, i.e. ISO 4796-1, or appropriate reference to thecorrespondending national standard.In addition, each bottle can bear an area with a surface suitable for mar
42、king with a pencil.Marks a) to c) may be moulded into the recessed base of the bottle, if the method of manufacture permits; otherwise, they may be indelibly marked, in any convenient position, by etching, sandblasting or with vitreous enamel.7.2 The closures of the bottles shall be marked with the
43、maximum permitted temperature for use or for sterilization, e.g. “max. 100 C”.NOTE Closures not marked with a temperature can only be used at ambient temperature.During sterilization, the closure may not be screwed more than one turn to enable pressure release. Otherwise, pressure increase in the bo
44、ttle can result in fracture.4 ISO 2016 All rights reservedBS EN ISO 4796-1:2016This page deliberately left blankThis page deliberately left blankBSI is the national body responsible for preparing British Standards and other standards-related publications, information and services.BSI is incorporated
