What is the exact well diameter of WHEATON 868806?
DWK specifies a 28.1 mm inside diameter at each well opening.
How many vials can one rack hold?
Each rack contains 50 positions in a 5 x 10 arrangement, intended for appropriately sized vials.
How many racks are included in a case?
The manufacturer supplies five individual racks per case, providing 250 total positions when all five racks are considered together.
What are the overall rack dimensions?
One rack measures 330 mm long x 170 mm wide x 30 mm high, or 33 x 17 x 3 cm.
Are these dimensions for the shipping carton?
No. They describe the individual rack. The shipping carton dimensions are not established in the reviewed manufacturer specifications.
Are the racks made from polypropylene?
Yes. DWK specifies white polypropylene (PP) construction.
Are the individual positions numbered?
The manufacturer describes alphanumeric indexing on the rack to support sample position identification.
Can the racks be stacked?
Yes. DWK identifies them as stackable, including when compatible vials are in place. The manufacturer does not establish a universal maximum loaded stack height in the reviewed SKU specifications.
Do the wells have drainage holes?
Yes. DWK describes an opening at the bottom of each well to facilitate drainage.
Can a vial with a 28 mm outside diameter fit?
A nominal 28 mm body diameter is within the stated 28.1 mm well ID. WHEATON's selection guide identifies certain 28 mm-diameter vials for rack 868806. Verify current vial tolerances and the complete container configuration before use.
Can I use a 30 mm outside-diameter vial?
Not in a nominal 28.1 mm opening. For larger vials, evaluate the separately designated WHEATON 868808 rack, which has 30.0 mm well openings. Verify practical clearance and vial fit.
Does the rack hold a specific vial volume?
Not universally. WHEATON's guide identifies certain 25 mL and 40 mL vials for this rack because they share suitable body dimensions. Capacity alone is not the correct selection criterion.
Are the racks autoclavable?
Yes. DWK lists autoclavability at 121°C for WHEATON 868806.
What autoclave cycle should be used?
DWK's general plasticware guidance describes a 121°C, approximately 15 psi, 20-minute cycle. The individual rack product record specifies 121°C but does not independently establish a validated rack-specific cycle. Follow the facility's approved procedure.
Are the racks sterile when purchased?
A supplied-sterile designation is not established in the reviewed manufacturer specifications. Autoclavability and supplied sterility are different characteristics.
Can the racks be cleaned with laboratory detergents?
DWK identifies the rack as easy to clean and provides general guidance on cleaning laboratory plasticware. Choose a detergent compatible with polypropylene and the actual residues.
Can this rack be used in an ISO-classified cleanroom?
Use in a classified environment depends on the facility's material introduction, cleaning, and contamination-control procedures. The rack is not assigned a product-specific ISO cleanliness class in the reviewed documentation.
What is the difference between 868806 and 868808?
Both have 50 positions and a 5 x 10 layout. Rack 868806 has 28.1 mm wells and is 330 mm long. Rack 868808 has 30.0 mm wells and is 337 mm long.
Are sample vials included?
No. The manufacturer case contains five vial racks. Vials and closures are separate products.
