Product Description
1. Overview
The Side Arm Distilling Flask belongs to our flask range and is mainly used for heating, reaction, distillation and multi-neck assembly. Standard sizes cover 50ml~3000ml. Suited to synthesis, extraction and distillation where several attachments share one vessel.
The body is made of borosilicate 3.3 glass; coefficient of expansion about 3.3×10⁻⁶/K, clearly better thermal shock resistance than soda-lime glass. It works between -30℃ to 150℃ (thermal shock within 120℃); chemically it resists water, acids, salt solutions and most organic solvents; not for hydrofluoric acid, hot concentrated phosphoric acid or strong alkali; smooth transparent wall, low adhesion. Level, interface and residue are easy to read, keeping transfer errors small.
When selecting, confirm medium, temperature and connection first, then fix the size: the medium decides the material, the temperature decides whether heating or autoclaving is possible, and the connection decides whether it mates with existing apparatus. For duties outside the normal range — hot concentrated alkali, fluoride media, vacuum or repeated thermal cycling — our engineers can confirm a suitable option.

3. Manufacturing and inspection
Parts are lamp-worked and blown from borosilicate tube or rod, annealed as a whole to relieve forming stress; joints and sealing faces ground in pairs, keeping items of the same size interchangeable. Work is carried out at controlled stations to prevent scratches and cross-contamination.
Each item is checked for appearance, dimensions and fit before dispatch; sampling covers capacity or graduation deviation, joint fit and wall uniformity. Items from the same batch stay consistent in size and feel, which simplifies central storage and reordering. Inspection records and batch information are available with the goods.
Product Comparison Notes
This entry uses Side Arm Distilling Flask as the baseline. Two further on-site entries are available for separate comparison: Candidate 1 — Asphalt Distilling Flask; Candidate 2 — Petroleum Distilling Flask. The two are listed separately and independently; neither substitutes for the other, and neither is stated to match the product on this page.
The site classifies this product within the flask range, records the structure as side arm, and lists 50ml ~ 3000ml in the specification column. This entry compares the category and the documented side-arm structure only; the site records no comparable interface-form field, so no interface form is stated here. Listing figures from external material belong to external products and are listed in the background block below, not as RichTech specifications.
