ConductScience Cover Slips 24x50mm, No. 1.5 (Pack of 20)
$32.00 per unit | 20 units per pack Bulk pricing: Pack of 20 at $640.00 ($32.00 per unit)
Glass cover slips manufactured to No. 1.5 thickness specification (0.17mm ± 0.01mm) with 24x50mm rectangular dimensions. These precision-ground borosilicate glass coverslips provide consistent optical properties for microscopic examination of tissue sections and larger biological specimens. The rectangular format accommodates elongated samples while maintaining the standard thickness required for high-resolution imaging with oil immersion objectives.
The No. 1.5 thickness represents the optimal balance between mechanical stability and minimal optical interference, making these coverslips compatible with modern microscopy techniques including fluorescence, confocal, and super-resolution imaging systems. The larger 24x50mm format provides extended sample area compared to standard square coverslips, particularly useful for serial sections, whole-mount preparations, and specimens requiring multiple fields of view.
How It Works
Cover slips function as protective barriers that maintain specimen hydration while providing optical clarity for microscopic observation. The borosilicate glass composition exhibits low fluorescence background and minimal birefringence, ensuring accurate transmission of light through the specimen to the objective lens. The No. 1.5 thickness (170 micrometers) matches the working distance specifications of modern high-numerical-aperture objectives, particularly oil immersion lenses designed for optimal resolution.
The rectangular geometry accommodates specimens that exceed the dimensions of standard square coverslips, allowing visualization of extended tissue sections or multiple sample areas under a single cover. The precision-ground surfaces maintain consistent thickness across the entire coverslip area, preventing focal plane variations that could compromise image quality during systematic scanning or automated imaging protocols.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Coverslip Dimensions | 24x50mm rectangular format | Standard formats are typically 22x22mm square | Provides nearly double the coverage area for larger specimens and serial sections. |
| Thickness Specification | No. 1.5 (0.17mm) | Entry-level options may use No. 1 (0.13-0.16mm) or No. 2 (0.19-0.25mm) | Optimized thickness for modern high-NA objectives and oil immersion systems. |
| Glass Composition | Borosilicate glass construction | Some alternatives use soda-lime glass | Lower thermal expansion coefficient and superior chemical resistance for demanding applications. |
| Surface Quality | Precision-ground optical surfaces | Basic formats may have standard glass finishing | Minimizes optical artifacts and maintains consistent thickness across entire surface area. |
These coverslips combine the extended coverage area of rectangular format with precision No. 1.5 thickness specification and borosilicate glass construction. The 24x50mm dimensions accommodate larger specimens while maintaining optical quality required for high-resolution microscopy applications.
Practical Tips
Store coverslips vertically in original packaging to prevent surface contact and potential scratching between adjacent pieces.
Why: Maintains optical surface quality and prevents contamination that could affect image clarity.
Use appropriate forceps with fine, smooth tips when handling coverslips to avoid applying excessive pressure or creating stress points.
Why: Prevents cracking and maintains structural integrity during mounting procedures.
Clean coverslips with lens tissue and appropriate solvents rather than paper towels or cloth materials.
Why: Prevents scratching of optical surfaces and eliminates lint contamination.
If air bubbles form during mounting, gently tap the coverslip with a blunt instrument while the mounting medium is still fluid.
Why: Air bubbles create optical discontinuities that interfere with imaging and can be mistaken for specimen artifacts.
Match the refractive index of mounting medium to the imaging requirements rather than using the same medium for all applications.
Why: Proper refractive index matching optimizes light transmission and minimizes optical aberrations.
Handle broken coverslips with forceps and dispose in designated sharps containers rather than regular laboratory waste.
Why: Prevents cuts and injuries while ensuring proper disposal of glass laboratory materials.

Compliance
What is the tolerance specification for No. 1.5 thickness?
No. 1.5 coverslips have nominal thickness of 0.17mm (170 micrometers) with typical tolerance of ±0.01mm, ensuring compatibility with high-NA objectives designed for this working distance.
Are these coverslips suitable for oil immersion microscopy?
Yes, the No. 1.5 thickness specification matches the design parameters of oil immersion objectives, providing optimal resolution and minimal spherical aberration.
Can these coverslips withstand organic solvents used in histological clearing?
Borosilicate glass construction provides resistance to standard histological solvents including xylene, toluene, and alcohols used in tissue processing protocols.
What mounting media are compatible with these coverslips?
Compatible with aqueous mounting media, permanent mounting resins, and temporary mounting solutions. Avoid mounting media with high refractive index mismatch to the glass.
How should coverslips be stored to maintain optical quality?
Store in original packaging in dust-free environment at room temperature. Avoid temperature cycling that could induce thermal stress in the glass.
Are these coverslips suitable for live cell imaging applications?
Yes, the rectangular format accommodates perfusion chambers and culture vessels while the optical quality supports high-resolution time-lapse imaging protocols.
