When requesting a quote for microscope cover glass, providing complete product information helps suppliers prepare a faster and more accurate quotation.
A message such as “Please quote cover glass” is usually not enough.
For distributors, importers, laboratories, and OEM buyers, a professional RFQ should clearly define the glass material, size, thickness, quantity, packaging, private label requirements, destination, and expected purchasing volume.
This guide explains what information buyers should include when requesting a microscope cover glass quotation.
Quick Answer: What Information Should Be Included in a Cover Glass RFQ?
A complete microscope cover glass RFQ should include:
Product type
Glass material
Size
Thickness
Thickness tolerance if required
Quantity
Packaging
Private label requirements
Delivery destination
Preferred trade term
Expected order frequency
Sample requirements
The more complete the specification, the easier it is for manufacturers to provide an accurate price.
1. Specify the Cover Glass Type
Start by telling the supplier what product you need.
Common options include:
Square Cover Glass
Rectangular Cover Glass
Circular Cover Glass
Soda Lime Cover Glass
Borosilicate Cover Glass
Super White Cover Glass
Hemocytometer Cover Glass
Do not simply write “microscope cover glass” if you already know the application or product type.
2. Confirm the Glass Material
Glass material can significantly affect both price and application.
Common options include:
Soda Lime Glass
A cost-effective choice for many routine microscopy applications.
Borosilicate Glass
Often selected when improved thermal or chemical characteristics are required.
Super White Glass
Selected when reduced visible tint and higher visual clarity are preferred.
If you are unsure which material is suitable, describe your application and ask the manufacturer for available options.
3. Provide the Exact Size
Always include the required dimensions.
Common cover glass sizes include:
18 × 18 mm
20 × 20 mm
22 × 22 mm
24 × 24 mm
24 × 32 mm
24 × 40 mm
24 × 50 mm
24 × 60 mm
For circular cover glass, provide the required diameter.
Avoid using only terms such as “standard size,” because different markets may use different specifications.
4. Specify the Thickness
Thickness is an important part of the RFQ.
Common cover glass grades may include:
No. 0
No. 1
No. 1.5
No. 2
Where possible, also provide the required thickness range.
For example:
No. 1.5 / approximately 0.16–0.19 mm
For demanding microscopy applications, thickness tolerance should also be specified.
5. Provide the Required Quantity
Quantity has a direct impact on price.
Tell the supplier whether you require:
Samples
Trial order
100 boxes
1,000 boxes
Pallet quantity
Container quantity
For distributors, it is also useful to provide estimated annual demand.
For example:
Initial order: 1,000 boxes
Estimated annual demand: 10,000–15,000 boxes
This helps the manufacturer provide more appropriate bulk pricing.
6. Confirm Packaging Requirements
Packaging should be clearly defined before quotation.
Provide information such as:
Pieces per box
Boxes per carton
Standard or customized box
Export carton requirements
Pallet requirement
Special protection requirements
Because cover glass is fragile, packaging can affect both product cost and shipping breakage.
7. State Whether You Need Private Label Packaging
If you are a distributor selling under your own brand, tell the supplier at the RFQ stage.
Private label requirements may include:
Customer logo
Custom box
Brand colors
Barcode
SKU
Lot number
Product label
Carton markings
Customized packaging may affect MOQ, unit price, and lead time.
8. Provide the Shipping Destination
Always provide the destination country or port when asking for freight-inclusive pricing.
For example:
Destination: Hamburg, Germany
or
Delivery Country: United States
This allows the supplier to estimate logistics costs more accurately.
9. Specify the Trade Term
If possible, tell the supplier which trade term you prefer.
Common terms may include:
EXW
FOB
CIF
CFR
For example:
Please quote FOB Shanghai.
or
Please quote CIF Hamburg.
Using the same trade term makes it easier to compare quotations from different suppliers.
10. Ask for MOQ
If the required quantity is uncertain, ask:
What is your MOQ for this specification?
MOQ may depend on:
Size
Thickness
Material
Packaging
Custom printing
Standard products usually have different MOQ requirements from private label products.
11. Ask for Sample Availability
Before placing a bulk order, request representative samples.
A useful RFQ can include:
Please advise whether samples are available before bulk order confirmation.
Samples allow buyers to inspect:
Size
Thickness
Optical clarity
Surface cleanliness
Edge quality
Packaging
For advanced microscopy, samples should also be tested in the actual laboratory workflow.
12. Ask for Lead Time
Ask the supplier to confirm:
Sample lead time
Production lead time
Private label lead time
Repeat-order lead time
This is especially important for distributors managing inventory.
13. Ask for Packaging Details
A professional quotation should ideally include:
Pieces per box
Boxes per carton
Carton dimensions
Net weight
Gross weight
These details help buyers estimate:
Freight
Warehouse space
Container utilization
Landed cost
14. Ask for Product Specifications
For technical comparison, request a product datasheet or specification sheet.
Important information may include:
Glass material
Dimensions
Thickness
Thickness tolerance
Surface quality
Packaging
Storage information
This makes it easier to compare multiple suppliers using the same criteria.

Common RFQ Mistakes
Asking Only for the Lowest Price
A price without a clear specification may not be useful.
Not Providing Thickness
Two cover glass products with the same dimensions may have different thickness specifications and prices.
Forgetting Packaging
Packaging affects both cost and breakage.
Not Mentioning Private Label Requirements
Custom boxes and labels may affect MOQ and lead time.
Comparing Different Trade Terms
FOB and CIF quotations should not be compared directly without adjusting for freight and related costs.
How to Compare Quotations After Receiving Them
Once quotations arrive, compare:
Specification + Unit Price + Packaging + MOQ + Lead Time + Freight + Quality + Supplier Capability
Do not compare price alone.
Make sure each supplier is quoting the same:
Material
Size
Thickness
Quantity
Packaging
Trade term
Otherwise, the quotations may not be directly comparable.

Frequently Asked Questions
What information do I need to request a cover glass quote?
Provide material, size, thickness, quantity, packaging, destination, and private label requirements if applicable.
Why does the supplier need the destination country?
The destination helps calculate freight, shipping method, packaging requirements, and landed-cost estimates.
Should I include annual demand in an RFQ?
Yes, especially for distributors. Estimated annual volume may help suppliers provide more suitable pricing and production planning.
Should I ask for samples before ordering?
Yes. Samples help confirm product specifications and quality before bulk purchasing.
Should I ask for FOB or CIF pricing?
It depends on your purchasing strategy. Using the same trade term across suppliers makes quotations easier to compare.
Does private label packaging affect the quotation?
Yes. Custom boxes, labels, logos, barcodes, and printing can affect MOQ, unit price, and lead time.
Why are quotations from different suppliers sometimes very different?
Differences may come from material, thickness, tolerance, quality level, packaging, quantity, or trade terms.
Conclusion
A professional microscope cover glass RFQ should provide enough information for the manufacturer to understand exactly what the buyer needs.
The most important details are:
Material + Size + Thickness + Quantity + Packaging + Branding + Destination + Trade Term
A clear RFQ helps buyers receive more accurate quotations, compare suppliers fairly, reduce unnecessary communication, and avoid specification mistakes before production.
For distributors and importers, spending a few extra minutes preparing a complete RFQ can save significant time and reduce purchasing risks later.
