Full title and description

St ISO 4796-1977 rus — International Standard ISO 4796:1977, "Laboratory glassware — Bottles" (Russian-language edition/adoption). The standard specifies an internationally acceptable series of laboratory bottles intended for the storage of liquid and solid chemicals and reagents, giving basic dimensional and design requirements to improve safe handling and pouring performance.

Abstract

ISO 4796:1977 defines a series of laboratory bottles (nominal capacities, outside diameters, neck designs and general shape) intended for general laboratory storage and handling of chemicals and reagents. The document emphasizes design features that reduce splashing and external run‑down during pouring (conical neck/shoulder and specifically shaped lip) and gives a preferred series of nominal capacities. The 1977 edition has since been withdrawn and its subject matter split into later parts (screw‑neck and conical‑neck bottles).

General information

• Status: Withdrawn / Annulled.
• Publication date: December 1977 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 71.040.20 — Laboratory ware and related apparatus; Technical committee ISO/TC 48.
• Edition / version: Edition 1 (1977).
• Number of pages: 2 pages (short technical specification).

Scope

Specifies a series of laboratory bottles suitable for the storage of liquid chemicals and reagents in general laboratory use. The standard covers nominal capacities and preferred outside diameters and neck dimensions for a range of sizes (from tens of millilitres to multi‑litre bottles) and gives general design guidance to avoid trapped air in the shoulder and to ensure the last drop transfers to the receiving vessel rather than running down the outside of the bottle. ISO 4796:1977 was later superseded by partized standards addressing screw‑neck and conical‑neck bottles.

Key topics and requirements

• Series of nominal capacities (e.g., 50, 100, 250, 500 mL; 1, 2, 5, 10 L) and associated outside diameters and minimum wall thicknesses.
• Conical (ground) neck / shoulder geometry to avoid trapped air and reduce splash/gulping during pouring.
• Outside rim/lip shape engineered to transfer the last drop to the receiving vessel and prevent run‑down the bottle exterior.
• General dimensional limits and tolerances for typical laboratory bottle sizes (reference values rather than exhaustive manufacturing drawings).
• Safety and handling considerations specific to storage and pouring of laboratory reagents.

Typical use and users

Used by laboratory equipment manufacturers, glassware designers, quality managers in chemical and biological laboratories, procurement teams specifying standard glassware, and national bodies publishing translations or national adoptions. Laboratories and suppliers referencing historic or legacy equipment documentation may consult this edition or its successors when dealing with older stocks or to trace design lineage. A Russian-language edition or national adoption copy is available from standards distributors for users requiring the Russian text.

Related standards

ISO 4796:1977 has been revised and split into parts: ISO 4796-1:2000 (Laboratory glassware — Bottles — Part 1: Screw‑neck bottles) and ISO 4796-2:2000 (Part 2: Conical‑neck bottles). Subsequent revisions include ISO 4796-1:2016 for the screw‑neck series. Users should consult the later parts for current technical requirements.

FAQ

Q: What is this standard?

A: ISO 4796:1977 is an International Standard titled "Laboratory glassware — Bottles" that specified a series of laboratory bottles and basic design requirements for safe storage and pouring of chemicals. It was published in December 1977 and later withdrawn.

Q: What does it cover?

A: It covers preferred nominal capacities, outside diameters, neck shapes and general design guidance (conical shoulder, lip shape) to reduce splashing and external run‑down during pouring. The document provided concise dimensional guidance rather than complete manufacturing drawings.

Q: Who typically uses it?

A: Glassware manufacturers, laboratory purchasers, standards editors, and laboratories dealing with legacy glassware or comparing historical and modern bottle specifications. National standards bodies and standards resellers also distribute translated or adopted copies (for example, Russian-language editions).

Q: Is it current or superseded?

A: ISO 4796:1977 has been withdrawn and superseded by later partized standards — notably ISO 4796-1:2000 (screw‑neck) and ISO 4796-2:2000 (conical‑neck); further revision activity updated part 1 in 2016. Users requiring current technical requirements should refer to those later parts.

Q: Is it part of a series?

A: Yes — the subject matter continued in a multipart series (ISO 4796-1 and ISO 4796-2) addressing different neck types; the multipart approach replaced the single 1977 document.

Q: What are the key keywords?

A: laboratory bottles, glassware, screw-neck bottles, conical-neck bottles, nominal capacity, pouring safety, ISO 4796.
