PolarStat Plus™

Medium viscosity formulation.

PolarStat Plus™ is an exceptional cryo embedding media that works well with an anti-roll plate or may be led off the blade with a brush. It is especially well-suited for Mohs cryostat sectioning.

• Now available in 4 optimal colors to accompany the traditional white formulation.
• This formulation freezes at -10°C.
• Optimal cutting temperature ranges from below-10°C to -40°C.
• Does not produce a powder residue while sectioning at -25°C or colder.
• Works with Auto Cryo Approach in Microm cryostats.
• No residue is left on slides during the staining procedure, thereby eliminating undesirable background staining.

Tissue Marking Dye

Our new tissue marking dyes are formulated to provide very bright and clear identification of microscopic areas of interest and to easily identify the orientation of excised tissue samples. These dyes are readily visible on cut frozen tissue sections. These dyes will not run, bleed, fade or lose intensity from tissue processing and/or during staining procedures in the histology laboratory.

• Permanent tissue marking dyes.
• Colors formulated to define margins without bleeding or fading.
• Durable, bright dyes hold permanently through processing and staining procedures.
• Unique lid design allows for complete removal or they may be conveniently flipped open with little risk of drying.
• Available in 2oz. flip-top bottles in the following colors:

Applications/intended use:

• Mohs surgery procedures to mark tissue specimens to map and identify the orientation and borders of tissue specimens.
• Pathology grossing of tissue to identify areas of interest and orientation of surgically excised tissue specimens.
• Marking surgical margins.
• Identifying serial segments of large tissues to ensure proper orientation and embedding.
• Identification of multiple pieces of tissues processed in one cassette
• May be used on fresh or fixed tissue.

Note: Pretreatment of tissue to be dyed with #27208, ColorBond™ Mordant may greatly enhance the performance of tissue marking dyes, especially with fatty tissues.

PELCO^® Histo/Cyto-Freeze™ Cryo Spray

Excellent for cooling liquid, semi-solid and solid specimens. Ideal for ultra-rapid freezing of fresh tissue, cooling of liquids to induce precipitation prior to filtering and cooling of field samples.

PELCO^® Histo/Cyto-Freeze™ delivers instant flash freezing for cryostat sectioning. It cools down to -60°F (-50°C) in just three seconds.

To cut frozen sections, mount sample directly on the microtome holder, simply spray to flash freeze and section. Time saving procedure and prevents water crystals built up caused by slower methods.
The provided nozzle delivers the freezing action exactly where it is needed. Contains 10 oz. pure, 100% virgin tetrafluoroethane for enhanced freezing and cooling performance.

Non-flammable, non-corrosive odorless gas. Ozone safe. Contains no CFC's.

NEW SEAL'N FREEZE^® CRYOTRAY^®
Cryo Embedding Molds & Freeze Box

developed to address common challenges in frozen tissue sample processing and storage

NEW SEAL'N FREEZE^® CRYOTRAY^® Molds

The SEAL’N FREEZE^® CRYOTRAY^® is a compact system of plastic cryo embedding molds with attached sealable lids. This tray system allows for batch processing of tissue samples in perfect uniform blocks that are ideal for cryo sectioning and storage.

Each disposable plastic SEAL’N FREEZE^® CRYOTRAY^® includes four individual molds which can be easily separated from the center connector by folding and tearing along the perforated borders.

SEAL’N FREEZE^® CRYOTRAY^® molds are available in two sizes:

• Intermediate: 15 L x 15 W x 5mm D (0.6 L x 0.6 W x 0.2" D), pkg/50 trays (200 molds)
• Large: 25 L x 30 W x 20mm D (1 L x 1.2 W x 0.8" D), pkg/50 trays (200 molds)

NEW SEAL’N FREEZE^® BOX

The SEAL’N FREEZE^® BOX is intended for the cryogenic freezing (also known as “snap” or “flash” freezing) of animal tissue samples for use in cryostat sectioning. Maximize your efficiency by using the SEAL’N FREEZE^®CRYOTRAY^® with the compact SEAL’N FREEZE^® BOX, which allows for convenient hands-free freezing. 

The SEAL’N FREEZE^® BOX allows users to freeze up to four samples simultaneously when used with SEAL’N FREEZE^® CRYOTRAY^® inserts. The box’s stainless steel case and foam lining ensures optimal temperature control throughout the freezing process. Its small, compact size ensures easy storage.

For the freezing media, liquid nitrogen or a slurry of dry ice and alcohol may be used in the SEAL’N FREEZE^® BOX.

Warnings:

• Only properly trained users should handle cryogenic freezing media such as liquid nitrogen and dry ice.
• Use the SEAL’N FREEZE^® BOX on a level surface only to prevent tipping.
• Never allow the freezing media to come in contact with skin. Ensure that the proper Cryo Safety Gear is used when handling the freezing media: cryo gloves, apron and safety glasses or face shield.
