Hoefer® Standard and Preparative Combs for Vertical Systems
Combs are precision machined from Teflon®, which is highly resistant to acids, bases, and all commonly used buffer systems. An important benefit of Teflon® combs, compared to other types, is that they are easily removed while maintaining gel integrity. They are lightweight and virtually unbreakable when used with reasonable care. Some combs have microtiter spacing for use with multi-channel pipettes.
- Standard Combs come attached to a standard back, which produces maximum well depths of 25 mm, except for the 28-well combs, which produce well depths of 15 mm. 15-well Standard Combs have microtiter spacing for use with multichannel pipettes.
- Preparative Combs have adjustable comb backs (10, 15, and 25 mm depth) and form 1 large preparative well plus 1 or 2 small reference wells.

Lab Armor® Bead Bath
Bead Baths from Lab Armor® are designed with the user in mind and are optimized to work with Lab Armor® Bath Beads. Bead Bath performs all the essentials, including warming, thawing, incubating, chilling and does so while maintaining a constant temperature just like a water bath. These baths deliver exceptional temperature uniformity up to 80°C. The baths are available in 6 L, 14 L, and 20 L sizes, with and without beads included.
- Uniform Temperatures
- With Bead Bath designed specifically for beads, temperatures are consistent and uniform everywhere in the bath. Thermal uniformity is an amazing ±5 °C at 37 °C and ± 1 °C at 65 °C. Since Bead Bath won't boil off like water, or pose danger of combustion like oil, it is ideal for most applications from 37°C to 400 °C.
- Fast Start
- Bead Bath gets up and running faster and you never need to turn it off. There is nothing to evaporate. Unlike a standard bead-filled water bath, Bead Bath allows you to achieve a new set temperature quickly, without long warm up delays, so you can make quick adjustments.
- Stays Organized
- Unlike water baths that require racks, floats and bottleneck weights, Bead Bath naturally holds things in place without accessories. The types and kinds of vessels that can be used with the Bead Bath aren't limited to water-tight containers. So you can safely incubate multiwall plates and petri dishes-or thaw samples without fear of water wicking under the lids. And vessels can be set into the beads at any angle for better thermal optimization.
- Low Maintenance
- Water baths must be routinely monitored, cleaned and maintained. While it is a good idea to keep an eye on Bead Bath, it rarely needs attention. A bi-weekly or monthly spritz of a biodegradable disinfectant is usually sufficient.

VistaLab™ 100 mL Reagent Reservoir Cooler
Reservoir cooler for VistaLab™ 100 mL reservoirs.
The VistaLab™ 100 mL Reagent Reservoir Cooler comes with three 100 mL VistaLab™ Reagent Reservoirs and three compatible lids. These coolers and reservoirs have multiple features to help to limit “dead volume” or leftover residual liquid. This superior low retention maximizes reagent recovery up to 67% better than comparable reservoirs.
The trough-within-a-trough design funnels remaining liquid into a secondary deep channel, so leftover drops can easily be aspirated, preventing reagent waste. The secondary trough also helps improve pipetting consistency, ensuring every channel of a multi-channel pipette can draw up equal volumes.
Additionally, reservoirs have a proprietary high-wettability, hydrophilic surface treatment that helps lower surface tension, causing liquid to spread rather than bead up. This also assists in the prevention of water droplets clinging to walls.
VistaLab™ reservoirs and reservoir coolers are ergonomic and easy to use with molded graduations, pour spouts at every corner, and a wide base for better stability.
Main Attributes
- Compatible with VistaLab™ polystyrene 100 mL reservoirs
- Cooler comes with three (3) sterile 100 mL reservoirs with lids
- Superior low retention maximizes reagent recovery
- Proprietary high wettability, hydrophilic surface treatment
- Trough-within-a-trough design channels “every last drop”
