Review: Dont be hesitant, these are top-notch and as described - The price was fantastic and they came really fast. Buying the lowest price scientific items can sometimes result in a sacrifice of quality but Karter Scientific makes good glassware plus these looked beautiful and the ground stopper fit perfect. My wife was a little worried about them being glass and arriving in a bag, however she was confused because they were in a little box inside an desertcart bag. They were completely undamaged and perfect condition. Plus I told her that's how you know they're legit boro glass, not the thin stuff some other sellers try to claim is 3.3 Borosilicate Glass! Review: Actually 10 ml - Used balance, a glass pipette plus an adjustable pipette at 10ml. QS mark matched both pipettes very close. Karter products have performed as advertised so far. ## Features - Capacity: 100ml - Class A - Height (with Stopper): 191mm / 7.5" (approx.) - Outside Diameter: 60mm / 2.4" (approx.) - Color: Amber ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B091V5H4YT | | Best Sellers Rank | #226,651 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #33 in Lab Volumetric Flasks | | Bottom Shape | Round | | Brand | Karter Scientific | | Brand Name | Karter Scientific | | Capacity | 100 ml | | Customer Reviews | 3.9 out of 5 stars 9 Reviews | | Graduation Interval | 100 ml | | Manufacturer | Karter Scientific | | Material | Glass | | Material Type | Glass | | Model Number | 253F3 | | Number of Items | 2 | | Part Number | 253F3 | | Specification Met | Astm, Iso | ## Images ![100ml Volumetric Flask, 3.3 Boro Glass, Class A, Ground Stopper, Amber, Karter Scientific (Pack of 2) - Image 1](https://m.media-amazon.com/images/I/41t8zUpfXnL.jpg) ![100ml Volumetric Flask, 3.3 Boro Glass, Class A, Ground Stopper, Amber, Karter Scientific (Pack of 2) - Image 2](https://m.media-amazon.com/images/I/41pk4DcIvqL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dont be hesitant, these are top-notch and as described *by N***B on July 13, 2026* The price was fantastic and they came really fast.
