VWR Small Latex Bulbs HS20622BV Review

Unboxing & First Thoughts on the VWR Small Latex Bulbs HS20622BV

The world of outdoor and tactical gear might seem a far cry from the laboratory, but precision and reliability are universal virtues. When it comes to handling sensitive liquids in the field – whether for water purification, medical treatments, or even makeshift repairs – having the right equipment is paramount. This brings us to the VWR Small Latex Bulbs HS20622BV, a seemingly simple yet potentially critical tool for anyone who needs controlled liquid dispensing in challenging environments. VWR, a well-known name in scientific supplies, offers these small bulbs as a solution for various liquid handling tasks.

My interest in these bulbs stemmed from a persistent issue: consistently and accurately dispensing small quantities of liquids during wilderness first aid and improvised gear repairs. Syringes can be bulky and difficult to clean in the field, and pouring directly from a container often leads to spills and wasted product. The promise of latex-free construction was also appealing, given increasing sensitivities and the potential for allergic reactions amongst team members in a group survival situation.

Upon receiving the package, I was immediately struck by the simplicity of the Hetlrow brand (Hawk Brand) product. The bulbs are indeed small, fitting comfortably in the palm of my hand. The light pink color, designed for easy recognition, is a practical touch that I appreciate. Compared to traditional latex bulbs, these feel slightly less elastic, which is expected given the latex-free material. I had previously considered using small plastic pipettes, but their rigidity and single-use nature made them less appealing for my needs. I also compared these to silicone bulbs from other brands, but those tended to be significantly more expensive.

My initial reaction was cautiously optimistic. The VWR Small Latex Bulbs HS20622BV seemed like a potentially elegant solution, but the proof would be in the pudding – or rather, in the precise dispensing of liquids under real-world conditions.


Real-World Testing: Putting VWR Small Latex Bulbs HS20622BV to the Test

First Use Experience

My first opportunity to test the VWR Small Latex Bulbs HS20622BV came during a mock wilderness survival exercise. We were practicing water purification using iodine tablets, and accurately measuring the iodine solution was crucial. The Small Latex Bulbs provided a far more controlled and spill-free method than pouring from the iodine bottle. Dispensing water into small containers was also made significantly easier.

The bulbs performed reasonably well in the cool morning air, maintaining their elasticity without becoming too stiff. However, I did notice that the suction power was slightly less than I had anticipated, requiring a firmer squeeze to draw up the desired amount of liquid. Even still, it was far easier than using improvised methods for liquid transfer.

Extended Use & Reliability

After several weeks of use, the VWR Small Latex Bulbs HS20622BV have held up remarkably well. I’ve used them to dispense everything from water and iodine to lubricant for firearms and even a quick fix of super glue. The latex-free material has shown no signs of degradation or cracking, even after exposure to various chemicals. A quick rinse with water is usually sufficient to clean them.

Compared to my previous experiences with latex bulbs (which tended to become sticky and brittle over time), these seem significantly more durable. While they may not have the same elasticity as latex, the added longevity and allergy-free properties make them a worthwhile trade-off. The ease of cleaning is a major plus, as it saves time and effort in the field.
