Hoefer® Standard Format Glass Plates for Vertical Systems
Standard format glass plates are for SE660, SE600X Chroma, SE600, SE640, SE410, and SE400 Vertical Gel Electrophoresis Units.
Run as many as four 0.75, 1.0, or 1.5 mm thick gels on SE600 Series units and two gels on the SE400 Series at one time under identical conditions using the double gel capacity Divider Plates. Insert a divider plate between the glass plates that make up a single gel sandwich. Place spacers on each side of the divider plate to form two gel cavities for pouring gels. This two gel “club sandwich” fits into the same casting stand and seals perfectly.

Texan™ Reagent Reservoirs
- Improved design
- Vol graduations to 150 mL
- a reinforced base that won't wobble on the counter, preventing spills
- a new easy-to-open latch that can be manipulated with one hand
- greater clarity for improved visibility of contents
Texan reagent reservoirs are reusable -- an environmentally sound alternative to disposable reagent reservoirs. Their extra-large capacity means fewer refills and time saved. The V-shaped basin is compatible with both eight- and twelve-place multiple pipettors with minimal reagent waste. Lids are removable -- attached with ball and socket hinges -- and latch tightly for secure storage of left-over reagents. With lids closed, Texan reagent reservoirs are stackable. A perimeter ridge on the lid prevents sliding. Construction is clear, chemical-resistant, autoclavable polypropylene. Molded graduation marks provide Vol indication at 25, 50, 75, 100, 125, and 150 mL.
Available sterile and non-sterile. Sterile reagent reservoirs are supplied in bags of 5, nonsterile in bags of 10, both within outer packages of 100.

Well Orienters for Microplates
For easy sample identification and pipetting.
96-Well Orienters are designed to simplify sample identification, pipetting accuracy, and workflow efficiency when working with microplates. Available as multi-colored orienters, orienter stickers, or reusable orienter cards, these tools eliminate confusion by clearly identifying rows and columns at a glance. Bright colors, sharp alpha-numeric markings, and precise alignment make it easy to distinguish samples in both vertical and horizontal orientations.
The Multi-Colored 96- and 384-Well Orienters use vibrant color patterns to instantly differentiate columns, helping prevent pipetting errors. It fits most standard flat- and round-bottom 96- and 384-well plates and is available in both horizontal and vertical formats.
96-Well Orienter Stickers provide a permanent labeling solution for microplates, with each well clearly marked by row and column. A scored paper backing allows for quick and accurate alignment on the underside of the plate.
The 96-Well Orienter Card is a thin, reusable plastic insert that slides beneath the plate, displaying crisp alpha-numeric characters for 96-, 48-, or 24-well microplates, eliminating the need for constant cross-referencing.
Together, these orienter solutions improve accuracy, save time, and reduce sample handling errors in research, diagnostic, and routine laboratory workflows.
