VEVOR’s labware assortment emphasizes precision and material integrity over generic lab supplies. Dewar liquid nitrogen tanks are available in four aluminum alloy sizes: 3L, 10L, 20L, and 30L. Each includes 6 canisters and a carry bag with straps for cryogenic storage in scientific, beauty, and semen preservation applications. Borosilicate glass, used for beakers, Erlenmeyer flasks, volumetric flasks, and test tubes, resists temperature stress and chemical reactions so that it can be reused in the laboratory. A 90-peg steel wire drying rack and a 100-piece set of 1mL glass Luer lock syringes complete the necessities every working lab needs on hand.
Storing cryogenic samples? 3 liters. Or running a full beaker-and-flask setup for a classroom of 30? VEVOR labware weighs in both. Dewar nitrogen tanks are available in sizes from small 3L to large 30L aluminum alloy containers, with 6 canisters and a carry case with straps. The collection includes borosilicate glassware and 1 mL Luer-lock syringes, designed for the thermal and chemical challenges of everyday laboratory work.
VEVOR labware suits several lab tasks, from long-term cryogenic storage to daily liquid handling. Here’s how they stack up regarding capacity and use.
VEVOR Dewar liquid nitrogen tanks are available in four fixed sizes of 3L, 10L, 20L, and 30L. All are made of aluminum alloy instead of steel, making them easier to move between a storage room and work area without compromising the vacuum-insulated wall that keeps liquid nitrogen at cryogenic temperatures for long stretches of time.
All sizes come with the same basic accessory kit: 6 canisters for organizing samples in the tank and a tote bag with straps for transfer between locations. The 3L tank is ideal for a single practitioner with a small batch of samples, typical in the beauty industry for cryotherapy treatments. For semen preservation or a scientific lab that needs to store several sample batches longer before the liquid nitrogen runs out, the 20L and 30L tanks offer sufficient volume.
All four sizes use the same canister-and-bag accessory arrangement, so stepping up in capacity means no new storage method to learn and only the larger size to account for. This set of four sizes covers most of what a growing lab needs, without VEVOR’s labware forcing a choice between too small and excessively big.
A laboratory beaker is one of the most commonly used items in any functioning lab, with a wide mouth and flat bottom that make it ideal for mixing chemicals and stirring solutions. You can also heat it directly over a burner or hot plate without tipping the container. They include clear volume markings on the side.
This lets a researcher read an approximate measurement without transferring the liquid to a separate measuring vessel first, speeding up routine sample processing. Beakers are constantly handled, heated from boiling to cold, and exposed to all sorts of reagents, so their glass must withstand more abuse than most other labware.
Beakers are used in virtually every lab application, from classroom demonstrations to professional research settings with active chemical reactions. That is why they’re usually the first purchase when building a lab’s glassware inventory from scratch. In VEVOR's labware lineup, beakers are the general-purpose workhorse; other, more specialized items like flasks and test tubes complement them rather than replace them.
Erlenmeyer flasks solve an issue beakers can’t: the narrow neck and sloped shoulder reduce the chance of splashing when swirling or vigorously mixing. This matters most when titrating a solution or performing a reaction that needs gentle hand agitation throughout the process. It also makes it easier to fit a stopper or lid, seal a sample for storage, or prevent evaporation during a prolonged reaction.
Volumetric flasks serve a more specific purpose than beakers or Erlenmeyer flasks: preparing a solution to one exact calibrated volume, not an estimated volume. A single fill line is etched around the neck of the flask, indicating the exact amount for which the flask is rated, so diluting a concentrated solution to a standardized concentration is simply a matter of filling to that one line rather than estimating against a set of graduated markings.
Both types depend on close tolerances for glass forming to remain accurate after repeated use, and that’s the sort of manufacturing uniformity that distinguishes reliable labware from those that wander out of calibration after a few uses.
At the other end of the volume scale from a Dewar tank or a big flask are glass test tubes: small vessels for individual samples stored, combined, and heated one at a time rather than in bulk. Their cylindrical design, with either a rounded or flat bottom, lets a tube sit upright in a rack when not in use.
A rack keeps several samples organized and separate throughout a multi-step diagnostic or research protocol rather than leaving them loose on a benchtop. Test tubes have the most diverse applications of all the glassware in a lab, from holding a small sample of reagent for a chemistry class to heating something over an open flame for a quick test.
Test tubes are used in much larger quantities than beakers or flasks, as a working lab needs only one sample per tube at a time and thus needs to be just as durable against repeated thermal cycling and handling as any other category in VEVOR's labware selection, if not more so due to the volume of use daily.
The type dictates a piece of labware's function, but glass composition and capacity determine whether it can withstand daily lab conditions and deliver accurate results.
Borosilicate glass is made by adding boron trioxide to the standard silica glass formula, which substantially lowers the coefficient of thermal expansion compared to soda-lime glass. Borosilicate glass can handle fast temperature changes. You can move a glass beaker from a cold counter straight to a hot plate without it cracking. Ordinary glass would break if you did this.
This glass also resists chemicals. The added boron keeps the surface from reacting with acids or solvents. Because it doesn't break down or leach into your samples, you can use it again and again.
This is why schools and science labs use borosilicate glass as their normal, everyday choice. Every beaker, flask, and test tube made by VEVOR uses this same glass. You can switch between different containers during an experiment without worrying about them cracking under heat.
VEVOR labware capacity varies from milliliters to liters, depending on what the item is meant to contain. Tiny 1 mL glass Luer lock syringes for accurate low-volume dispensing. Sold in a set of 100 reusable items with 14 Ga blunt-tip needles. For lab use, veterinary work, or anywhere you need accurate tiny-volume dispensing without the sharps risk of a hypodermic needle.
On the other end, Dewar tanks for liquid nitrogen range from 3L to 30L, providing bulk cryogenic space for sample banks or supply storage that must survive a prolonged holding period between refills. Between those two extremes are beakers, flasks, and test tubes in capacities a typical bench technique calls for, from a few milliliters for a test tube to several hundred milliliters or a liter for a regular beaker or flask.
A 90-peg steel wire drying rack completes the capacity picture from a completely new perspective. It holds a quantity of glassware rather than liquid, so an entire batch of washed beakers, flasks, and tubes can air-dry at once, rather than one at a time. The trick to managing a lab’s storage space and budget is to match capacity to the real work, not just buy the biggest option.

VEVOR's Dewar nitrogen tanks are available in 3L, 10L, 20L, and 30L sizes. All are made from aluminum alloy and include six canisters plus a carry bag.
Borosilicate glass resists sudden temperature changes and chemical reactions, making it more durable and reliable for repeated laboratory use than regular soda-lime glass.
Beakers are used for everyday mixing and heating. Erlenmeyer flasks have a narrow neck to help prevent splashing, especially when swirling liquids or performing titrations.
The Luer lock set contains 100 reusable 1mL glass syringes, each paired with a 14-gauge blunt-tip needle for safe, precise laboratory and veterinary liquid handling.
No, volumetric flasks are for preparing solutions to a single precise volume. For general mixing, beakers are better because they have wider mouths and graduated markings.
