Now, we'll go over detailed advice on how to write a cover letter that lands you the laboratory assistant role you want.

STEP 1

Format your cover letter’s header correctly

First, your laboratory assistant cover letter must include a header with key details like the letter's date, recipient, and a formal greeting. This header follows the standard business letter format and conveys professionalism.

PRO TIP

If you can't find the hiring manager's name, never use the generic “To Whom It May Concern.“ There are better ways to address a cover letter without a name, such as “Dear Hiring Manager.“

STEP 2

Introduce yourself in the opening paragraph

Your laboratory assistant cover letter must quickly capture the hiring manager's attention. Introduce yourself with your professional title and key qualifications, such as in-demand skills or specialized expertise. For example, see how these two opening paragraph examples compare:

Strong opening paragraph example:

As a laboratory technician with over three years of experience in clinical settings, I am excited to apply for the laboratory assistant position at BioMed Research. My expertise in sample analysis and data collection has equipped me for this role, especially through my work on a pathogen detection project that reduced test result errors by 15% within six months, enhancing overall accuracy.

Weak opening paragraph example:

Hey there, I'm reaching out about the lab assistant position at GreenTech Labs. I've done some work in this area, and I'm really keen on joining the team to help out.

PRO TIP

If a current employee has referred you for this position, mention this in the opening paragraph. Our referral cover letter openings article shows you how to do this.

STEP 3

Share relevant achievements in the body paragraph

Use your laboratory assistant cover letter's body paragraph to differentiate yourself from other job seekers by expanding on a specific achievement, providing insight into your career goals, or sharing a little bit about your work ethic and values.

Check icon

Strong body paragraph example:

As a laboratory assistant at XYZ Labs, I demonstrated expertise in conducting precise experiments and managing data efficiently. Handling complex equipment, I improved testing accuracy by 20%, reflecting my proficiency with technical tools and attention to detail. Collaborating with scientists, I facilitated seamless teamwork that increased project deadlines met by 15%, showcasing my communication and problem-solving skills. These achievements highlight my ability to thrive in a dynamic research environment.

Cross icon

Weak body paragraph example:

I am interested in being a laboratory assistant because I need a job and think I could do well in it. I have a little bit of lab experience but not much, and I learn kind of quickly. I have not used lab equipment a lot, but I can probably learn. With a chance, I might be able to do well.

STEP 4

Finish by encouraging next steps

The closing paragraph will be the final section of your laboratory assistant cover letter. Use this section to share any final skills or qualifications you possess and state your interest in a future interview. Go for confident tone and proper sign-off before signing your name.

Strong closing paragraph:

My extensive experience with laboratory equipment and meticulous attention to detail make me a valuable candidate for the laboratory assistant position at BioWorks Laboratories. I am eager to bring my skills to your esteemed team and contribute to your innovative research. Thank you for considering my application; I am looking forward to the possibility of discussing this opportunity further in an interview.
Best regards,
Emily Connor

Weak closing paragraph:

I think I might be okay as a laboratory assistant at your place because I'm interested in science and don't mind learning new procedures. Let me know if you think I suit the position, and thanks for taking the time to look at my application.
Best regards,
Michael
