Let’s Dive into Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500
The Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500 might not seem like the kind of product that ignites passion. But for anyone who’s wrestled with subpar sample storage in the field, or struggled to maintain the integrity of critical specimens, these caps represent a genuine upgrade. Labcon promises a secure seal, ultra-clear resin compatibility, and freedom from RNase, DNase, and endotoxins, all at a competitive price of $113.99.
My introduction to these caps stemmed from a frustrating experience during a field research project studying waterborne pathogens in remote alpine lakes. Standard push-cap microcentrifuge tubes repeatedly failed, leaking precious samples during transport back to the lab, compromising months of work. I needed a reliable sealing solution for sample storage that wouldn’t break the bank.
Upon receiving the Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500, my first impression was positive. The caps are packaged in resealable bags, keeping them clean and organized. The blue color offers easy visual identification, a huge plus when sorting through multiple samples.
Compared to generic screw caps I had previously used, these Labcon caps feel noticeably more robust. The ethylene propylene O-ring gives a sense of confidence in their ability to create a tight seal. While I also considered caps from Corning and Eppendorf, the price point and specific claims of ultra-clear resin compatibility with existing tubes made the Labcon option more attractive.
Initially, I was cautiously optimistic. I had been burned before by promises of leak-proof seals, but the design and specifications of these caps suggested a different outcome. I was eager to put them to the test in the rugged field conditions where sample integrity is paramount.
Real-World Testing: Putting Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500 to the Test
First Use Experience
My first field test with the Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500 took place during a week-long water quality assessment in the Boundary Waters Canoe Area Wilderness. We collected samples from various lakes and streams, immediately transferring them to microcentrifuge tubes capped with these Labcon closures. The temperature ranged from near freezing at night to a humid 70°F during the day.
The caps performed flawlessly. The screw-top design allowed for easy closure, even with wet or gloved hands, and there were zero leaks detected during the canoe portages or overnight storage. Their reliability was immediately apparent and welcomed.
Extended Use & Reliability
After six months of consistent use in diverse field conditions – from desert soil sampling in Arizona to stream sediment analysis in Alaska – the Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500 have proven remarkably durable. There are no signs of wear and tear on the caps.
Maintenance is virtually non-existent. Simply rinsing them with distilled water is enough to remove any residue. Compared to my previous experience with push-cap tubes and their recurring failures, these Labcon caps are a game-changer, consistently outperforming expectations in terms of reliability and sample preservation.
Breaking Down the Features of Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500
Specifications
- Volume: While these are caps only, they are designed for use with standard microcentrifuge tubes (typically 0.5mL to 2.0mL). This compatibility is crucial for seamless integration with existing lab workflows.
- Tube Style: These caps are designed for screw-top microtubes. This allows for a much more secure closure compared to standard push-cap tubes.
- Unit: Pack of 500. A large quantity ensures you’re stocked for extensive projects, minimizing the need for frequent reordering.
- Maximum RCF: Although the tubes determine the RCF, these caps are designed to withstand high speeds (up to 20,000 g) without compromising the seal. This is important for applications involving centrifugation.
- Material: The caps are constructed from an ultra-clear resin. This provides excellent visibility of the sample within the tube.
- Seal: They feature an ethylene propylene O-ring for a secure, leak-proof seal. This is critical for maintaining sample integrity during storage and transport.
- Certifications: RNase-, DNase-, and Endotoxin-Free; FDA CFR 21 compliant. These certifications are essential for sensitive applications requiring purity and compliance with regulatory standards.
Performance & Functionality
The Labcon SuperClear Screw Cap Microtubes 3600-877-000 Nonsterile Caps Only, Pack of 500 excel at their primary job: providing a secure, leak-proof seal for microcentrifuge tubes. They consistently maintain sample integrity even under demanding field conditions, such as temperature fluctuations and rough handling during transportation. The universal screw threads ensure compatibility with most popular brands of screw-cap microtubes.
The only potential area for improvement lies in the cap design. While the blue color is helpful for visual identification, offering a broader range of colors in the pack could further enhance organization and sample differentiation. Otherwise, these caps meet and exceed expectations for reliable sample storage.
Design & Ergonomics
The design of these caps prioritizes functionality and ease of use. The materials used feel robust. The screw-top mechanism allows for easy closure, even with gloved hands.
There is virtually no learning curve. Simply screw the cap onto the tube for a secure seal.
