Product Description

1. Overview

The PP Wide Mouth Bottle belongs to our laboratory plasticware and is mainly used for storage, transfer, filtration and handling support. Standard sizes cover 125ml~1000ml. Replacing glass where light weight, drop resistance and moderate chemical resistance matter.

The body is made of polypropylene (PP); low density and good fatigue resistance, suited to parts opened or squeezed repeatedly. It works between -10℃ to 120℃, briefly up to 130℃; chemically it resists most acids, alkalis and salt solutions; not for strong oxidizing acids, halogenated or some aromatic hydrocarbons; translucent, tough, tolerant of repeated flexing and dropping. Surface condition and residue are easy to verify, so cleaning completeness is obvious.

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 injection moulded in one piece, air-cooled after mould release; interchangeability held by mould precision, 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.

Applications

Typical applications

Purpose by model

This category covers many items with differing duties; refer to the specific model and quotation.

Daily laboratory work

Suited to daily sampling, handling and pairing.

Confirm duty first

Define the medium, handling method and interface before choosing a model.

Set-up building and modification

Connects, diverts and reduces so that parts with different joints form a complete train.

Gas and liquid path control

Handles on-off, splitting and regulation as a common node in gas and dropping circuits.

Teaching and training

Clear structure makes it easy to explain connection order and handling.

Selection Guide

Choose by duty

Duty first, size second

Define the handling method, contact medium and temperature range before choosing material and interface.

Interface must match

Confirm the interface form before pairing with other apparatus; mismatches leak or will not assemble.

Material by medium

Choose material according to the contact medium and operating temperature; refer to the specification block.

Special requirements on request

Non-standard sizes, special interfaces or volume customisation are quoted separately.

Size versus throughput

Match size to the volume per run and the number of runs a day; oversize vessels add cleaning load, undersize ones force repeated batches.

Reading accuracy needed

Choose graduated or single-mark items when accurate metering matters; skip the accuracy premium for rough transfer work.

Service condition guide

Condition	Suitability	Notes
Ambient storage and transfer	Suitable	most acids, alkalis and salt solutions
Heating (water bath)	Conditional	stay below 120℃ for long periods
Flame or dry heat	Not suitable	softens and deforms
Vacuum service	Conditional	only heavy-wall items; thin walls collapse
Hydrofluoric acid	Suitable	PP resists HF
Strong oxidizing acids	Not suitable	concentrated nitric or sulfuric acid attacks it
Halogenated and aromatic solvents	Not suitable	may swell or stress-crack
Autoclaving	Suitable	standard 121℃ cycle

Usage Guide

Standard procedure

Step 01

Inspect for cleanliness, cracks and chipped edges before use; a crack spreads quickly under heat or load, so retire the item at once and never patch it.

Step 02

Assemble as required for various laboratory operations and confirm the connection is secure.

Step 03

Pour or transfer slowly along the wall to avoid impact on the base and splashing; with volatile or foaming media a slow stream cuts losses and cross-contamination.

Step 04

Do not heat this item: no flame drying and no high-temperature oven drying.

Step 05

Clean promptly after use and choose the drying method according to the material; soak stubborn residues first and never scrape the wall with hard tools.

Step 06

Before first use, clean according to the material; soak in dilute acid where appropriate, rinse thoroughly and dry. New items may carry processing aids, so clean before contact with samples.

Step 07

Store without stacking or impact, in a ventilated and dry place; long stacking deforms the base, and volumetric ware should stand on its own.

Step 08

Keep one batch together and label different sizes separately to avoid picking the wrong item; once mixed, the batch is hard to identify when a problem appears.

Step 09

Keep a usage log with the commissioning date, media contacted and cleaning method, so replacement timing and traceability stay clear.

Maintenance & Notes

⚠️ Safety & handling notes

Keep away from heat

Never flame-dry or oven-dry at high temperature; keep away from hot plates and heat sources.

Prevent mechanical damage

Avoid impact, dropping and scratching; never carry by a thin or weak section.

Clean promptly

Clean immediately after use; dried residues are harder to remove. Avoid abrasive cleaning tools.

Drying by material

Air-dry or dry at low temperature; volumetric ware must never be oven-dried.

Periodic inspection

Check for cracks, deformation and seal failure after long use and replace when needed.

Identification and traceability

Items should carry a clear label and usage record; mixed use makes cleaning history and media contact untraceable.

Retirement criteria

Stop using an item for critical work once it is cracked, chipped, worn at the graduations or leaking; never patch and return it to service.
