VWR Vwr Pipet Repeater 2ml TG-50360-002 Review

Let’s Dive into VWR Vwr Pipet Repeater 2ml TG-50360-002

The VWR Vwr Pipet Repeater 2ml TG-50360-002 is presented as an affordable and reliable device designed to streamline repetitive pipetting tasks. Manufactured by VWR, this lab glassware promises to multiply the pipetting power of a user by enabling the simultaneous addition of multiple volumes of liquid using a single instrument. This eliminates the tediousness of using multiple pipettes or stoppers, a feature that immediately caught my attention given my experience in high-throughput lab settings.

My initial interest in the VWR Vwr Pipet Repeater 2ml TG-50360-002 stemmed from a persistent need to improve efficiency and reduce errors in our lab’s titration experiments. We frequently perform serial dilutions and need to quickly dispense accurate volumes repeatedly, making repetitive strain injuries a concern. I hoped this repeater would offer a faster, more consistent, and ergonomically sound solution.

Upon unboxing, the VWR Vwr Pipet Repeater 2ml TG-50360-002 felt solid and well-constructed, though the packaging was rather basic for a device at this price point. The positive displacement piston mechanism was visible through the clear housing, giving me confidence in its purported accuracy. The blowout tip also seemed robust, promising complete liquid dispensing.

Compared to other repetitive pipettors I’ve used, such as the Eppendorf Repeater M4 and the Brand HandyStep S, the VWR model initially appeared simpler in design, lacking some of the advanced programming features. I chose the VWR Vwr Pipet Repeater 2ml TG-50360-002 because its emphasis on chemical resistance and the “affordable” claim (despite the $649.99 price tag) suggested it might be a cost-effective solution for our diverse range of reagents. It was worth investigating if the simplicity translated to reliable performance.

My first impression was cautiously optimistic. The device felt comfortable in hand, but the real test would be its performance under pressure in the lab. The hefty price tag also raised expectations significantly; it needed to perform exceptionally well to justify the investment.

Real-World Testing: Putting VWR Vwr Pipet Repeater 2ml TG-50360-002 to the Test

First Use Experience

My first test involved using the VWR Vwr Pipet Repeater 2ml TG-50360-002 in our standard ELISA assay, which requires dispensing 50 µL of multiple reagents into a 96-well plate. I tested it alongside our standard multi-channel pipette for a direct comparison. The VWR repeater was noticeably faster for repetitive dispensing tasks, completing the plate in about two-thirds of the time.

The device performed well in standard lab conditions, and I tested it with both aqueous solutions and slightly viscous buffers. Dispensing accuracy appeared consistent, but I noted some minor dripping with the more viscous solutions when the repeater was held at an angle. This was easily mitigated by holding the tip vertically.

The initial learning curve was minimal; the repeater’s operation is straightforward and intuitive. I experienced no major issues during the first use, though the dispensing button required a slightly firmer press than I initially expected.

Extended Use & Reliability

After a month of regular use, the VWR Vwr Pipet Repeater 2ml TG-50360-002 has proven to be a reliable workhorse in our lab. We’ve integrated it into several standard protocols, significantly reducing the time required for repetitive dispensing tasks. The positive displacement system delivers consistently accurate volumes, as verified by gravimetric analysis.

Durability has been impressive. Despite daily use and exposure to various chemicals, the device shows no signs of wear and tear. The plastic housing remains unblemished, and the piston mechanism continues to operate smoothly.

Maintenance is simple. Wiping down the exterior with a damp cloth is usually sufficient. The tip is easily replaceable and autoclavable, ensuring sterility for critical applications.

Compared to our previous experiences with other repetitive pipettes, the VWR Vwr Pipet Repeater 2ml TG-50360-002 stands out for its robust construction and consistent performance. While it lacks some of the advanced features of more expensive models, its reliability and ease of use make it a valuable asset in our lab. However, I still find the $649.99 price high for the features provided.

Breaking Down the Features of VWR Vwr Pipet Repeater 2ml TG-50360-002

Specifications

The VWR Vwr Pipet Repeater 2ml TG-50360-002 boasts the following specifications:

• Description: VWR PIPET REPEATER 2ML
• Catalog Number: 71001-648
• Volume: 2 ml (This refers to the maximum volume the syringe tip can hold; dispensed volumes are smaller and adjustable).
• Mechanism: Positive displacement piston.
• Tip: Blowout tip design.
• Chemical Resistance: Excellent, suitable for a wide range of lab reagents.

These specifications are crucial for several reasons. The positive displacement piston ensures accurate dispensing, even with viscous or volatile liquids, unlike air-displacement pipettes which can be affected by these properties. The blowout tip ensures complete dispensing of the liquid, minimizing reagent waste and improving accuracy. The chemical resistance is essential for versatility in a lab environment where a wide range of reagents are used.

Performance & Functionality

The VWR Vwr Pipet Repeater 2ml TG-50360-002 performs its job admirably, providing accurate and repeatable dispensing of liquids. The positive displacement mechanism ensures that the delivered volume is consistent, regardless of the liquid’s viscosity or density.

The primary strength of this device is its simplicity and reliability. It consistently delivers accurate volumes and requires minimal maintenance. The weakness lies in the limited volume range; it’s only suitable for dispensing volumes within the range supported by the 2 ml syringe tip.

The VWR Vwr Pipet Repeater 2ml TG-50360-002 largely meets expectations for a simple and reliable repetitive pipette. It doesn’t offer the advanced features of more expensive models, but it provides accurate and consistent performance for routine dispensing tasks.

Design & Ergonomics

The VWR Vwr Pipet Repeater 2ml TG-50360-002 features a lightweight and ergonomic design, making it comfortable to hold and operate for extended periods. The materials used are durable and chemically resistant, ensuring longevity in a lab environment. The weight is well balanced which contributes to user comfort.
