# Utile 20 mL Glass Test Tubes, 50-Pack

Utile glass test tubes are listed as a 50-pack of 20 mL borosilicate tubes, with cork stoppers and a cleaning brush. Their stated 16 × 150 mm size and claimed wall thickness suit small-volume storage and general lab or craft use, but the listing gives conflicting dimensions and capacity details to verify.

## At a glance

- Listing describes round-bottom tubes with flat mouths for small-volume use.
- The claimed borosilicate material is described as having good chemical durability.
- A tube brush is described as helping with cleaning, and corks as reusable after cleaning.

## Pros

- A stated 50-tube quantity and included corks and brush cover common storage and cleaning needs.
- The stated 1.0mm-1.2mm wall thickness provides a useful sizing detail for buyers comparing glass tubes.

## Cons

- Glass is fragile, so these tubes require careful handling.

## Before you buy

- The listing is inconsistent about tube size and capacity: the title and capacity detail say 20ml, while the style detail says 16x150mm. It also lists the parcel weight as both 204 g and 204.12 g. Confirm the selected listing’s tube dimensions and capacity before ordering. The seller states that glassware may arrive cracked in transit.

## In the box

- Glass test tubes (Included)
- Cork stoppers (Check selected pack): Claimed in the title and product description, but not in the explicit included-components list.
- Tube brush (Check selected pack): Claimed in the title and product description, but not in the explicit included-components list.

## A good fit for

- Buyers needing a multipack of small glass tubes for classroom activities, crafts or general sample storage.
- Users who want cork closures and a brush included for cleaning.

## Less suited to

- Buyers who need confirmed tube dimensions or capacity without checking the conflicting listing details.
- Uses where fragile glassware is unsuitable.

## Customer feedback

Aggregate ratings lean strongly positive, with most ratings in the five-star category and the remainder in the four-star category. This is a small rating sample and provides no detail about tube dimensions, breakage in transit or how the corks and brush perform, so it cannot resolve the listing’s conflicting size information.

## Frequently asked questions

### How many test tubes are listed?
The listing states 50 tubes, but confirm the selected listing details because its size and capacity information is inconsistent.
### What are the listed tube capacity and dimensions?
The title and capacity detail state 20 mL, while the style detail gives 16x150mm. Check the selected listing to confirm the actual tube size.
### Are corks and a cleaning brush included?
The title and product description claim cork stoppers and a brush. The explicit included-components field names only glass test tubes, so confirm the bundle contents on the selected listing.
